Windows 2000

It has been suggested that Windows 2000 Server be merged into this article or section. (Discuss)

Windows 2000 (also referred to as Win2K, W2K or Windows NT 5.0) is a preemptible and interruptible, graphical, business-oriented operating system that was designed to work with either uniprocessor or symmetric multi-processor (SMP) 32-bit Intel x86 computers. It is part of the Microsoft Windows NT line of operating systems and was released on February 17, 2000. Windows 2000 comes in four versions: Professional, Server, Advanced Server, and Datacenter Server. Additionally, Microsoft offers Windows 2000 Advanced Server- Limited Edition, which released in 2001 and runs on 64-bit Intel Itanium microprocessors. Windows 2000 is classified as a hybrid-kernel operating system, and its architecture is divided into two modes: user mode and kernel mode. The kernel mode provides unrestricted access to system resources and facilitates the user mode, which is heavily restricted and designed for most applications.

All versions of Windows 2000 have common functionality, including many system utilities such as the Microsoft Management Console (MMC) and standard system management applications such as a disk defragmentation utility. Support for people with disabilities has also been improved by Microsoft across their Windows 2000 line, and they have included increased support for different languages and locale information. All versions of the operating system support the Windows NT filesystem, NTFS 5, the Encrypted File System (EFS), as well as basic and dynamic disk storage. Dynamic disk storage allows different types of volumes to be used. The Windows 2000 Server family has enhanced functionality, including the ability to provide Active Directory services (a hierarchical framework of resources), Distributed file system (a file system that supports sharing of files) and fault-redundant storage volumes.

Windows 2000 can be installed and deployed to an enterprise through either an attended or unattended installation. Unattended installations rely on the use of answer files to fill in installation information, and can be performed through a bootable CD using Microsoft Systems Management Server (SMS), by the System Preparation Tool (Sysprep).

History

Windows 2000 originally descended from the Microsoft Windows NT operating system product line. Originally called Windows NT 5, Microsoft changed the name to Windows 2000 on October 27th, 1998. [1] It was also the first Windows version that was released without a code name, though Windows 2000 Service Pack 1 was codenamed "Asteroid" and Windows 2000 64-bit was codenamed "Janus" (not to be confused with Windows 3.1, which had the same codename). The first beta for Windows 2000 was released on September 27, 1997 and several further betas were released until Beta 3 which was released on April 29, 1999. From here Microsoft issued three release candidates from between July to November 1999 and finally released the operating system to partners on December 12, 1999. [2] The public received the full version of Windows 2000 on February 17, 2000 and the press immediately hailed it as the most stable operating system Microsoft had ever released. Novell, however, was not so impressed with Microsoft's new directory service architecture as they found it to be less scalable or reliable than their own Novell Directory Services (NDS) technology. [3] On September 29, 2000, Microsoft released Windows 2000 Datacenter. Microsoft released Service Pack 1 (SP1) on August 15, 2000, Service Pack 2 (SP2) on May 16, 2001, Service Pack 3 (SP3) on August 29, 2002 and its last Service Pack (SP4) on June 26, 2003. Microsoft has stated that they will not release a Service Pack 5, but instead, have offered an "Update Rollup" for Service Pack 4. Microsoft phased out all development of their Java Virtual Machine (JVM) from Windows 2000 in Service Pack 3.

Windows 2000 has since been superseded by newer Microsoft operating systems. Microsoft has replaced Windows 2000 Server products with Windows Server 2003, and Windows 2000 Professional with Windows XP Professional. Windows Neptune started development in 1999, and was supposed to be the home-user edition of Windows 2000. However, the project lagged in production time – and only one alpha release was built. Windows Me was released as a substitute, and the Neptune project was forwarded to the production of Whistler (Windows XP). The only elements of the Windows project which were included in Windows 2000 were the ability to upgrade from Windows 95 or Windows 98, and support for the FAT32 file system.

Several notable security flaws have been found in Windows 2000. Code Red and Code Red II were famous (and highly visible to the worldwide press) computer worms that exploited vulnerabilities of the indexing service of Windows 2000's Internet Information Services (IIS). In August 2003, two major worms named the Sobig worm and the Blaster worm began to attack millions of Microsoft Windows computers, resulting in the largest down-time and clean-up cost ever. The worms have also had political consequences as many companies in several countries started to call for government action to prevent further damages from Windows worms.

Architecture

The Windows 2000 operating system architecture consists of two layers (user mode and kernel mode), with many different modules within both of these layers.

Windows 2000 is a highly modular system that consists of two main layers: a user mode and a kernel mode. The user mode refers to the mode in which user programs are run. Such programs are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external devices. All user mode applications access system resources through the executive which runs in kernel mode.

User mode

User mode in Windows 2000 is made of subsystems capable of passing I/O requests to the appropriate kernel mode drivers by using the I/O manager. Two subsystems make up the user mode layer of Windows 2000: the environment subsystem and the integral subsystem.

The environment subsystem was designed to run applications written for many different types of operating systems. These applications, however, run at a lower priority than kernel mode processes. There are three main environment subsystems:

  1. Win32 subsystem runs 32-bit Windows applications and also supports Virtual DOS Machines (VDMs), which allows MS-DOS and 16-bit Windows 3.x (Win16) applications to run on Windows.
  2. OS/2 environment subsystem supports 16-bit character-based OS/2 applications and emulates OS/2 1.3 and 1.x, but not 2.x or later OS/2 applications.
  3. POSIX environment subsystem supports applications that are strictly written to either the POSIX.1 standard or the related ISO/IEC standards.

The integral subsystem looks after operating system specific functions on behalf of the environment subsystem. It consists of a security subsystem (grants/denies access and handles logons), workstation service (helps the computer gain network access) and a server service (lets the computer provide network services).

Kernel mode

Kernel mode in Windows 2000 has full access to the hardware and system resources of the computer. The kernel mode stops user mode services and applications from accessing critical areas of the operating system that they should not have access to.

Each object in Windows 2000 exists in its own namespace. This is a screenshot from SysInternal's WinObj

The executive interfaces with all the user mode subsystems. It deals with I/O, object management, security and process management. It contains various components, including:

  • Object manager: a special executive subsystem that all other executive subsystems must pass through to gain access to Windows 2000 resources. This essentially is a resource management infrastructure service that allows Windows 2000 to be an object oriented operating system.
  • I/O Manager: allows devices to communicate with user-mode subsystems by translating user-mode read and write commands and passing them to device drivers.
  • Security Reference Monitor (SRM): the primary authority for enforcing the security rules of the security integral subsystem. [4]
  • IPC Manager: short for Interprocess Communication Manager, manages the communication between clients (the environment subsystem) and servers (components of the executive).
  • Virtual Memory Manager: manages virtual memory, allowing Windows 2000 to use the hard disk as a primary storage device (although strictly speaking it is secondary storage).
  • Process Manager: handles process and thread creation and termination
  • PnP Manager: handles Plug and Play and supports device detection and installation at boot time.
  • Power Manager: the power manager coordinates power events and generates power IRPs.
  • The display system is handled by a device driver contained in Win32k.sys. The Window Manager component of this driver is responsible for drawing windows and menus while the GDI (graphical device interface) component is responsible for tasks such as drawing lines and curves, rendering fonts and handling palettes.

The Windows 2000 Hardware Abstraction Layer, or HAL, is a layer between the physical hardware of the computer and the rest of the operating system. It was designed to hide differences in hardware and therefore provide a consistent platform to run applications on. The HAL includes hardware specific code that controls I/O interfaces, interrupt controllers and multiple processors.

The microkernel sits between the HAL and the executive and provides multiprocessor synchronization, thread and interrupt scheduling and dispatching, trap handling and exception dispatching. The microkernel often interfaces with the process manager. [5] The microkernel is also responsible for initialising device drivers at bootup that are necessary to get the operating system up and running.

Kernel mode drivers exist in three levels: highest level drivers, intermediate drivers and low level drivers. The Windows Driver Model (WDM) exists in the intermediate layer and was mainly designed to be binary and source compatible between Windows 98 and Windows 2000. The lowest level drivers are either legacy Windows NT device drivers that control a device directly or can be a PnP hardware bus.

Common functionality

Certain features are common across all versions of Windows 2000 (both Professional and the Server versions), among them being NTFS 5, the Microsoft Management Console (MMC), the Encrypting File System (EFS), dynamic and basic disk storage, usability enhancements and multi-language and locale support. Windows 2000 also has several standard system utilities included as standard. As well as these features, Microsoft introduced a new feature to protect critical system files, called Windows File Protection (WFP). This prevents programs (with the exception of Microsoft's update programs) from replacing critical Windows system files and thus making the system inoperable. [6] Microsoft recognised that the infamous Blue Screen of Death (or stop error) could cause serious problems for servers that needed to be constantly running and so provided a system setting that would allow the server to automatically reboot when a stop error occurred. Users have the option of dumping the first 64KB of memory to disk (the smallest amount of memory that is useful for debugging purposes, also known as a minidump), a dump of only the kernel's memory or a dump of the entire contents of memory to disk, as well as write that this event happened to the Windows 2000 event log. In order to improve performance on computers running Windows 2000 as a server operating system, Microsoft gave administrators the choice of optimising the operating system for background services or for applications.

NTFS 5

Windows 2000 supports disk quotas, which can be set via the "Quotas" tab found in the hard disk properties dialog box.

Microsoft released the third version of the NT File System (NTFS) — also known as version 5.0 — in Windows 2000; this introduced quotas, file-system-level encryption (called EFS), sparse files and reparse points. Sparse files allow for the efficient storage of data sets that are very large yet contain many areas that only have zeroes. Reparse points allow the object manager to reset a file namespace lookup and let file system drivers implement changed functionality in a transparent manner. Reparse points are used to implement Volume Mount Points, Directory Junctions, Hierarchical Storage Management, Native Structured Storage and Single Instance Storage. Volume mount points and directory junctions allow for a file to be transparently referred from one file or directory location to another.

Encrypting File System

The Encrypting File System (EFS) introduced strong encryption into the Windows file world. It allowed any folder or drive on an NTFS volume to be encrypted transparently to the end user. EFS works in conjunction with the EFS service, Microsoft's CryptoAPI and the EFS File System Run-Time Library (FSRTL). As of February 2004, its encryption has not been compromised.

EFS works by encrypting a file with a bulk symmetric key (also known as the File Encryption Key, or FEK), which is used because it takes a relatively smaller amount of time to encrypt and decrypt large amounts of data than if an asymmetric key cipher is used. The symmetric key that is used to encrypt the file is then encrypted with a public key that is associated with the user who encrypted the file, and this encrypted data is stored in the header of the encrypted file. To decrypt the file, the file system uses the private key of the user to decrypt the symmetric key that is stored in the file header. It then uses the symmetric key to decrypt the file. Because this is done at the file system level, it is transparent to the user. [7] Also, in case of a user losing access to their key, support for recovery agents that can decrypt files has been built in to the EFS system.

Basic and dynamic disk storage

Windows 2000 introduced the Logical Disk Manager for dynamic storage. All versions of Windows 2000 support three types of dynamic disk volumes (along with basic storage): simple volumes, spanned volumes and striped volumes:

  • Simple volume: this is a volume with disk space from one disk.
  • Spanned volumes: multiple disks spanning up to 32 disks. If one disk fails, all data in the volume is lost.
  • Striped volumes: also known as RAID-0, a striped volume stores all its data across several disks in stripes. This allows better performance because disk read and writes are balanced across multiple disks.

Windows 2000 also added support for iSCSI protocol.

Accessibility support

The Windows 2000 onscreen keyboard map allows users who have problems with using the keyboard to use a mouse to input text.

Microsoft made an effort to increase the usability of Windows 2000 for people with visual and auditory impairments and other disabilities. They included several utilities designed to make the system more accessible:

  • FilterKeys: These are a group of keyboard related support for people with typing issues, and include:
    • SlowKeys: Windows is told to disregard keystrokes that are not held down for a certain time period
    • BounceKeys: multiple keystrokes to one key to be ignored within a certain timeframe
    • RepeatKeys: allows users to slow down the rate at which keys are repeated via the keyboard's keyrepeat feature
  • ToggleKeys: when turned on, Windows will play a sound when either the CAPS LOCK, NUM LOCK or SCROLL LOCK keys are pressed
  • MouseKeys: allows the cursor to be moved around the screen via the numeric keypad instead of the mouse
  • On screen keyboard: assists those who are not familiar with a given keyboard by allowing them to use a mouse to enter characters to the screen
  • SerialKeys: gives Windows 2000 the ability to support speech augmentation devices
  • StickyKeys: makes modifier keys (ALT, CTRL and SHIFT) become "sticky" — in other words a user can press the modifier key, release that key and then press the combination key. Normally the modifier key must remain pressed down to activate the sequence.
  • On screen magnifier: assists users with visual impairments by magnifying the part of the screen they place their mouse over.
  • Narrator: Microsoft Narrator assists users with visual impairments with system messages, as when these appear the narrator will read this out via the sound system
  • High contrast theme: to assist users with visual impairments
  • SoundSentry: designed to help users with auditory impairments, Windows 2000 will show a visual effect when a sound is played through the sound system

Language & locale support

Windows 2000 has support for many languages other than English. It supports Arabic, Armenian, Baltic, Central European, Cyrillic, Georgian, Greek, Hebrew, Indic, Japanese, Korean, Simplified Chinese, Thai, Traditional Chinese, Turkic, Vietnamese and Western European languages. [8] It also has support for many different locales, a list of which can be found on Microsoft's website.

System utilities

The Microsoft Management Console (MMC) is used for administering Windows 2000 computers.

Windows 2000 introduced the Microsoft Management Console (MMC), which is used to create, save, and open administrative tools. Each of the tools is called a console, and most consoles allow an administrator to administer other Windows 2000 computers from one centralised computer. Each console can contain one or many specific administrative tools, called snap-ins. Snap-ins can be either standalone (performs one function), or extensions (adds functionality to an existing snap-in). In order to provide the ability to control what snap-ins can be seen in a console, the MMC allows consoles to be created in author mode or created in user mode. Author mode allows snap-ins to be added, new windows to be created, all portions of the console tree can be displayed and for consoles to be saved. User mode allows consoles to be distributed with restrictions applied. User mode consoles can have full access granted user so they can make whatever changes they desire, can have limited access so that users cannot add to the console but they can view multiple windows in a console, or they can have limited access so that users cannot add to the console and also cannot view multiple windows in a console. [9]

The Windows 2000 Computer Management console is capable of performing many system tasks. It is pictured here starting a disk defragmentation.

The main tools that come with Windows 2000 can be found in the Computer Management console (found in Administrative Tools in the Control Panel). This contains the event viewer — a means of seeing events and the Windows equivalent of a log file, a system information viewer, the ability to view open shared folders and shared folder sessions, a device manager and a tool to view all the local users and groups on the Windows 2000 computer. It also contains a disk management snap-in, which contains a disk defragmenter as well as other disk management utilities. Lastly, it also contains a services viewer, which allows users to view all installed services and to stop and start them on demand, as well as configure what those services should do when the computer starts.

The REGEDIT.EXE utility on Windows 2000. The REGEDT32.EXE utility showing the same part of the registry.

Windows 2000 comes bundled with two utilities to edit the Windows registry. One acts like the Windows 9x REGEDIT.EXE program and the other could edit registry permissions in the same manner that Windows NT's REGEDT32.EXE program could. REGEDIT.EXE has a left-side tree view that begins at "My Computer" and lists all loaded hives. REGEDT32.EXE has a left-side tree view, but each hive has its own window, so the tree displays only keys. REGEDIT.EXE represents the three components of a value (its name, type, and data) as separate columns of a table. REGEDT32.EXE represents them as a list of strings. REGEDIT.EXE was written for the Win32 API and supports right-clicking of entries in a tree view to adjust properties and other settings. REGEDT32.EXE was also written for the Win32 API and requires all actions to be performed from the top menu bar. Because REGEDIT.EXE was directly ported from Windows 98, it does not support permission editing (permissions do not exist in Windows 9x). Therefore, the only way to access the full functionality of an NT registry was with REGEDT32.EXE, which uses the older multiple document interface (MDI), which newer versions of regedit do not use. Windows XP was the first system to integrate these two programs into one, adopting the REGEDIT.EXE behavior with the additional NT functionality.

The System File Checker (SFC) also comes bundled with Windows 2000. It is a command line utility that scans system files and verifies whether they were signed by Microsoft and works in conjunction with the Windows File Protection mechanism. It can also repopulate and repair all the files in the Dllcache folder. [10]

Recovery Console

The Recovery Console is usually used to recover unbootable systems.

The Recovery Console is an application that is run from outside the installed copy of Windows and that enables a user to perform maintenance tasks that cannot be run from inside of the installed copy, or cannot be feasibly run from another computer or copy of Windows 2000. It is usually used, however, to recover the system from errors causing booting to fail, which would render other tools useless.

It presents itself as a simple command line interface. The commands are limited to ones for checking and repairing the hard drive(s), repairing boot information (including NTLDR), replacing corrupted system files with fresh copies from the CD, or enabling/disabling services and drivers for the next boot.

The console can be accessed in one of two ways:

  1. Starting from the Windows 2000 CD, and choosing to enter the Recovery Console instead of continuing with setup, or
  2. Installing the Recovery Console via Winnt32.exe, with the /cmdcons switch. However, the console can then only be used if the system boots to the point where NTLDR can start it.

Server family functionality

The Windows 2000 server family consists of Windows 2000 Server, Windows 2000 Advanced Server and Windows 2000 Datacenter Server. They all have advanced functionality not found in Windows 2000 Professional, among these features are support for DFS, Active Directory and advanced fault-tolerant volumes.

Distributed File System

The Distributed File System, or DFS, allows shares in multiple different locations to be logically grouped under one folder, or DFS root. When users try to access a share that exists off the DFS root, the user is really looking at a DFS link and the DFS server transparently redirects them to the correct file server and share. A DFS root can only exist on a Windows 2000 version that is part of the server family, and only one DFS root can exist on that server.

There can be two ways of implementing DFS on Windows 2000: through standalone DFS, or through domain-based DFS. Standalone DFS allows for only DFS roots that exist on the local computer, and thus does not use Active Directory. Domain-based DFS roots exist within Active Directory and can have their information distributed to other domain controllers within the domain — this provides fault tolerance to DFS. DFS roots that exist on a domain must be hosted on a domain controller or on a domain member server. The file and root information is replicated via the Microsoft File Replication Service (FRS). [11]

Active Directory

Active Directory allows administrators to assign enterprise wide policies, deploy programs to many computers, and apply critical updates to an entire organization, and is one of the main reasons why many corporations have moved to Windows 2000. Active Directory stores information about its users and can act in a similar manner to a phone book. This allows all of the information and computer settings about an organization to be stored in a central, organized database. Active Directory Networks can vary from a small installation with a few hundred objects, to a large installation with millions of objects. Active Directory can organise groups of resources into a single domain and can link domains into a contiguous domain name space together to form trees. Groups of trees that do not exist within the same namespace can be linked together to form forests.

Active Directory can only be installed on a Windows 2000 Server, Advanced Server or Datacenter Server computer, and cannot be installed on a Windows 2000 Professional computer. It requires that a DNS service that supports SRV resource records be installed, or that an existing DNS infrastructure be upgraded to support this functionality. It also requires that one or more domain controllers exist to hold the Active Directory database and provide Active Directory directory services.

Volume fault tolerance

Along with support for simple, spanned and striped volumes, the server family of Windows 2000 also supports fault tolerant volume types. The types supported are mirrored volumes and RAID-5 volumes:

  • Mirrored volumes: the volume contains several disks, and when data is written to one it is mirrored to the other disks. This means that if one disk fails, the data can be totally recovered from the other disk. Mirrored volumes are also known as RAID-1.
  • RAID-5 volumes: a RAID-5 volume consists of multiple disks, and it uses block-level striping with parity data distributed across all member disks. Should a disk fail in the array, the parity blocks from the surviving disks are combined mathematically with the data blocks from the surviving disks to reconstruct the data on the failed drive "on-the-fly" (this works with various levels of success).

Versions

Microsoft released various versions of Windows 2000 to cater to different markets and business needs. It released Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server and Windows Datacenter Server:

  • Windows 2000 Professional was designed as the desktop operating system for businesses and power users. It is the basic unit of Windows 2000, and the most common. It offers greater security and stability than many of the previous Windows desktop operating systems. It supports up to two processors, and can address up to 4 GBs of RAM.
  • Windows 2000 Server products share the same user interface with Windows 2000 Professional, but contain additional components for running infrastructure and application software. A significant component of the server products is Active Directory, which is an enterprise-wide directory service based on LDAP. Additionally, Microsoft integrated Kerberos network authentication, replacing the often-criticised NTLM authentication system used in previous versions. This also provided a purely transitive-trust relationship between Windows 2000 domains in a forest (a collection of one or more Windows 2000 domains that share a common schema, configuration, and global catalogue, being linked with two-way transitive trusts). Furthermore, Windows 2000 introduced a DNS server which allows dynamic registration of IP addresses.
  • Windows 2000 Advanced Server is a variant of Windows 2000 Server operating system designed for medium-to-large businesses. It offers clustering infrastructure for high availability and scalability of applications and services, including main memory support of up to 8 gigabytes (GB) on Page Address Extension (PAE) systems and the ability to do 8-way SMP. It has support for TCP/IP load balancing and enhanced two-node server clusters based on the Microsoft Cluster Server (MSCS) in the Windows NT Server 4.0 Enterprise Edition.

[12] A limited edition 64 bit version of Windows 2000 Advanced Server was made available via the OEM Channel. It also supports failover and load balancing.

  • Windows 2000 Datacenter Server is a variant of the Windows 2000 Server that is designed for large businesses that move large quantities of confidential or sensitive data frequently via a central server. As with Advanced Server, it supports clustering, failover and load balancing. Its system requirements are normal, but are compatible with vast amounts of power:
    • A Pentium-class CPU at 400 MHz or higher - up to 32 are supported in one machine
    • 256 MB of RAM - up to 64 GB is supported in one machine
    • Approximately 1 GB of available disk space

Deployment

Windows 2000 can be deployed to a site via various methods. It can be installed onto servers via traditional media (such as via CD) or via distribution folders that reside on a shared folder. Installations can be attended or unattended. An attended installation requires the manual intervention of an operator to choose options when installing the operating system. Unattended installations are scripted via an answer file, or predefined script in the form of an INI file that has all the options filled in already. The Winnt.exe or Winnt32.exe program then uses that answer file to automate the installation. Unattended installations can be performed via a bootable CD, using Microsoft Systems Management Server (SMS), via the System Preparation Tool (Sysprep), via running the Winnt32.exe program using the /syspart switch or via running the Remote Installation Service (RIS).

The Syspart method is started on a standardised reference computer — though the hardware need not be similar — and it copies the required installation files from the reference computer's hard drive to the target computer's hard drive. The hard drive does not need to be in the target computer and may be swapped out to it at any time, with hardware configuration still needing to be done later. The Winnt.exe program must also be passed a /unattend switch that points to a valid answer file and a /s file to point to the location of one or more valid installation sources.

Sysprep allows the duplication of a disk image on an existing Windows 2000 Server installation to multiple servers. This means that all applications and system configuration settings will be copied across to the new Windows 2000 installations, but it also means that the reference and target computers must have the same HALs, ACPI support, and mass storage devices — though Windows 2000 automatically detects plug and play devices. The primary reason for using Sysprep is for deploying Windows 2000 to a site that has standard hardware and that needs a fast method of installing Windows 2000 to those computers. If a system has different HALs, mass storage devices or ACPI support, then multiple images would need to be maintained.

Systems Management Server can be used to upgrade system to Windows 2000 to multiple systems. Those operating systems that can be upgraded in this process must be running a version of Windows that can be upgraded (Windows NT 3.51, Windows NT 4, Windows 98 and Windows 95 OSR2.x) and those versions must be running the SMS client agent that can receive software installation operations. Using SMS allows installations to happen over a wide geographical area and provides centralised control over upgrades to systems.

Remote Installation Services (RIS) are a means to automatically install Windows 2000 Professional (and not Windows 2000 Server) to a local computer over a network from a central server. Images do not have to support specific hardware configurations and the security settings can be configured after the computer reboots as the service generates a new unique security ID (SID) for the machine. This is required so that local accounts are given the right identifier and do not clash with other Windows 2000 Professional computers on a network. [13] RIS requires that client computers are able to boot over the network via either a network interface card that has a Pre-Boot Execution Environment (PXE) boot ROM installed or that it has a network card installed that is supported by the remote boot disk generator. The remote computer must also meet the Net PC specification. The server that RIS runs on must be Windows 2000 Server and the server must be able to access a network DNS Service, a DHCP service and the Active Directory services. [14]

Total cost of ownership

In October 2002, Microsoft commissioned IDC to determine the total cost of ownership (TCO) for enterprise applications on Windows 2000 versus the TCO of Linux on the same enterprise applications. IDC looked at security and other infrastructure tasks, and Web Serving. According to the report, Windows 2000 had a lower TCO for four infrastructure items and Linux had a lower TCO for web serving. IDC's report was based on telephone interviews of IT executives and managers of 104 North American companies in which they determined what they were using for a specific workload for file, print, security and networking services.

IDC determined that the four areas where Windows 2000 had a better TCO than Linux — over a period of five years for an average organization of 100 employees — were in the use of file, print, network infrastructure and security infrastructure. They determined, however, that Linux had a better TCO than Windows 2000 when it came to web serving. The report also found that the greatest cost was not in the procurement of software and hardware, but in staffing costs and downtime. The report did not take into consideration the impact of downtime to the profitability of the business (although they did apply a 40% productivity factor, in order to recognize that employees are not entirely unproductive during periods of IT infrastructure downtime) though it did find that Linux servers had less unplanned downtime than Windows 2000 Servers. They found that most Linux servers ran less workload per server than Windows 2000 servers and also found that none of the businesses they interviewed used 4-way SMP Linux computers. IDC also did not take into account specific application servers — servers that need low maintenance and are provided by a specific vendor — when they performed their study. The report did emphasise that TCO was only one factor in considering whether to use a particular IT platform, and also noted that as management and server software improved and became better packaged the overall picture that was being shown in their report could change. [15]

[15]. In Islam, the former office of Caliph held similar meaning, as the leader of all Muslims, subordinate only to the prophet Muhammad. The report did emphasise that TCO was only one factor in considering whether to use a particular IT platform, and also noted that as management and server software improved and became better packaged the overall picture that was being shown in their report could change. In the Discordian religion, a pope is "every single man, woman, and child on this Earth." (page 00036 of the Principia Discordia). IDC also did not take into account specific application servers — servers that need low maintenance and are provided by a specific vendor — when they performed their study. In the Russian Orthodox Church it is not unusual for a village priest to be called a "pope". They found that most Linux servers ran less workload per server than Windows 2000 servers and also found that none of the businesses they interviewed used 4-way SMP Linux computers. The heads of the Coptic Church and the Eastern Orthodox Church of Alexandria are also called "popes", the former being called "Coptic Pope" or "Pope of Alexandria" and the latter called "Pope and Patriarch of Alexandria and All Africa"; the parallel construction "Pope of Rome" is frequently used in the Eastern churches.

The report did not take into consideration the impact of downtime to the profitability of the business (although they did apply a 40% productivity factor, in order to recognize that employees are not entirely unproductive during periods of IT infrastructure downtime) though it did find that Linux servers had less unplanned downtime than Windows 2000 Servers. "The Black Pope" is a derogatory name given to the Superior General of the Society of Jesus due to the Jesuits' practice of wearing black cassocks (compared to the pope's always wearing white robes), and to the order's specific allegiance to the Roman pontiff. The report also found that the greatest cost was not in the procurement of software and hardware, but in staffing costs and downtime. Though antipope movements were significant at one time, they are now overwhelmingly minor, fringe causes. They determined, however, that Linux had a better TCO than Windows 2000 when it came to web serving. The existence of an antipope is usually due either to doctrinal controversy within the Church, or to confusion as to who is the legitimate pope at the time (see Papal Schism). IDC determined that the four areas where Windows 2000 had a better TCO than Linux — over a period of five years for an average organization of 100 employees — were in the use of file, print, network infrastructure and security infrastructure. An antipope is a person who claims the Pontificate without being canonically and properly elected to it.

IDC's report was based on telephone interviews of IT executives and managers of 104 North American companies in which they determined what they were using for a specific workload for file, print, security and networking services. Some objectors to the papacy occasionally refer to the Catholic Church and its members by the pejorative term papist to point up what they believe to be an inappropriate focus of attention on the office and an improper attribution of certain divine favors ex officio. According to the report, Windows 2000 had a lower TCO for four infrastructure items and Linux had a lower TCO for web serving. They also argue that not even the worst of the corrupt popes used the office to try to rip the doctrine of the Church from its apostolic roots, and that this is evidence that the office is divinely protected. IDC looked at security and other infrastructure tasks, and Web Serving. Peter after he denied Jesus). In October 2002, Microsoft commissioned IDC to determine the total cost of ownership (TCO) for enterprise applications on Windows 2000 versus the TCO of Linux on the same enterprise applications. Defenders of the papacy argue that the Bible shows God as willingly giving privileges even to corrupt men (citing examples like some of the kings of Israel, the apostle Judas Iscariot, and even St.

[14]. An omniscient and omnibenevolent God, some argue, would not have given those people the powers claimed for them by the Catholic Church. The server that RIS runs on must be Windows 2000 Server and the server must be able to access a network DNS Service, a DHCP service and the Active Directory services. Peter, like Alexander VI and Callixtus III from the Borgia family, were so corrupt as to be unfit to wield power to bind and loose on Earth or in Heaven. The remote computer must also meet the Net PC specification. For instance, some argue that claimed successors to St. [13] RIS requires that client computers are able to boot over the network via either a network interface card that has a Pre-Boot Execution Environment (PXE) boot ROM installed or that it has a network card installed that is supported by the remote boot disk generator. Some objectors to the Papacy use empirical arguments, pointing to the corrupt characters of some of the holders of that office.

This is required so that local accounts are given the right identifier and do not clash with other Windows 2000 Professional computers on a network. These denominations tend to be more heterogeneous amongst themselves than the aforementioned hierarchical churches, and their views regarding the Papacy and its institutional legitimacy (or lack thereof) vary considerably. Images do not have to support specific hardware configurations and the security settings can be configured after the computer reboots as the service generates a new unique security ID (SID) for the machine. These denominations vary from simply not accepting the pope's authority as legitimate and valid, to believing that the pope is the Antichrist or the False Prophet spoken in the Book of Revelation. Remote Installation Services (RIS) are a means to automatically install Windows 2000 Professional (and not Windows 2000 Server) to a local computer over a network from a central server. In Western Christianity, these objections — and the vehement rhetoric they have at times been cast in — both contributed to, and are products of, the Protestant Reformation. Using SMS allows installations to happen over a wide geographical area and provides centralised control over upgrades to systems. The Papacy's complex relationship with the Roman and Byzantine Empires, and other secular states, and the Papacy's territorial claims in Italy, are another focal point of these objections; as is the monarchical character of the office of pope.

Those operating systems that can be upgraded in this process must be running a version of Windows that can be upgraded (Windows NT 3.51, Windows NT 4, Windows 98 and Windows 95 OSR2.x) and those versions must be running the SMS client agent that can receive software installation operations. Other non-Catholic Christian denominations do not accept the doctrine of Apostolic Succession, or do not understand it in hierarchical terms, and therefore do not accept the claim that the pope is heir either to Petrine primacy of honour or to Petrine primacy of jurisdiction or they reject both claims of honor or jurisdiction, as well as claims of Papal Infallibility, as unscriptural. Systems Management Server can be used to upgrade system to Windows 2000 to multiple systems. Several of these communities refer to such claims as "Ultramontanism.". If a system has different HALs, mass storage devices or ACPI support, then multiple images would need to be maintained. Because none of them recognise the First Vatican Council as truly ecumenical, they regard its definitions concerning jurisdiction and Infallibility (and anathematisation of those who do not accept them) as invalid. The primary reason for using Sysprep is for deploying Windows 2000 to a site that has standard hardware and that needs a fast method of installing Windows 2000 to those computers. In any event, these churches see no foundation at all to papal claims of universal immediate jurisdiction, nor to claims of Papal Infallibility.

This means that all applications and system configuration settings will be copied across to the new Windows 2000 installations, but it also means that the reference and target computers must have the same HALs, ACPI support, and mass storage devices — though Windows 2000 automatically detects plug and play devices. The primacy is therefore regarded primarily as a consequence of the pope's position as bishop of the original capital city of the Roman Empire, a definition explicitly spelled out in the 28th canon of the Council of Chalcedon. Sysprep allows the duplication of a disk image on an existing Windows 2000 Server installation to multiple servers. Peter was ever bishop of Rome at all. The Winnt.exe program must also be passed a /unattend switch that points to a valid answer file and a /s file to point to the location of one or more valid installation sources. Peter in any unique sense not true of any other bishop, or raise questions about whether St. The hard drive does not need to be in the target computer and may be swapped out to it at any time, with hardware configuration still needing to be done later. However, these churches generally reject that the Pope is the successor to St.

The Syspart method is started on a standardised reference computer — though the hardware need not be similar — and it copies the required installation files from the reference computer's hard drive to the target computer's hard drive. Some non-Roman-Catholic Christian communities, such as the Assyrian Church of the East, the Oriental Orthodox Church, the Eastern Orthodox Church, the Old Catholic Church, the Anglican Communion, the Independent Catholic Churches, and even some Lutherans, accept the doctrine of Apostolic Succession, and therefore accept (to varying extents) the papal claims to a primacy of honour. Unattended installations can be performed via a bootable CD, using Microsoft Systems Management Server (SMS), via the System Preparation Tool (Sysprep), via running the Winnt32.exe program using the /syspart switch or via running the Remote Installation Service (RIS). However, the pope's authority is not undisputed outside the Roman Catholic Church; these objections differ from denomination to denomination, but can roughly be outlined as (1.) objections to the extent of the primacy of the pope; and (2.) objections to the institution of the Papacy itself. The Winnt.exe or Winnt32.exe program then uses that answer file to automate the installation. The pope's position as Supreme Pontiff of the Universal Church is dogmatic and therefore not open to debate or dispute within the Roman Catholic Church; the First Vatican Council anathematised all who dispute the pope's primacy of honour and of jurisdiction (it is lawful to discuss the precise nature of that primacy, provided that such discussion does not violate the terms of the Council's Dogmatic Constitution). Unattended installations are scripted via an answer file, or predefined script in the form of an INI file that has all the options filled in already. From this term is derived the name Sedevacantist, which designates a category of dissident, schismatic Catholics who maintain that there is no canonically and legitimately elected pope, and that there is therefore a Sede Vacante; one of the most common reasons for holding this belief is the idea that the reforms of the Second Vatican Council and especially the replacement of the Tridentine Mass with the Novus Ordo Missae are heretical, and that, per the dogma of Papal infallibility (see above), it is impossible for a valid pope to have done these things.

An attended installation requires the manual intervention of an operator to choose options when installing the operating system. The Latin term sede vacante ("vacant seat") refers to a papal interregnum, the period between the death of the pope and the election of his successor. Installations can be attended or unattended. Traditionally, the new pope takes the Papal oath (the so-called "Oath against modernism") at his coronation, but Popes John Paul I, John Paul II, and Benedict XVI have all refused to do so. It can be installed onto servers via traditional media (such as via CD) or via distribution folders that reside on a shared folder. Another famed part of the coronation was the lighting of a torch which would flare brightly and promptly extinguish, with the admonition Sic transit gloria mundi ("Thus fades worldly glory"). Windows 2000 can be deployed to a site via various methods. There the pope was crowned with the triregnum and he gave his first blessing as pope, the famous Urbi et Orbi ("to the City [Rome] and to the World").

It also supports failover and load balancing. Peter's Basilica, with the newly-elected pope borne in the sedia gestatoria. [12] A limited edition 64 bit version of Windows 2000 Advanced Server was made available via the OEM Channel. Until 1978, the pope's election was followed in a few days by a procession in great pomp and circumstance from the Sistine Chapel to St. It released Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server and Windows Datacenter Server:. He then announces the new pope's Christian name along with the new name he has adopted as his regnal name. Microsoft released various versions of Windows 2000 to cater to different markets and business needs. Peter's Square the following proclamation: Annuntio vobis gaudium magnum! Habemus Papam! ("I announce to you a great joy! We have a pope!").

The types supported are mirrored volumes and RAID-5 volumes:. The senior Cardinal Deacon then announces from a balcony over St. Along with support for simple, spanned and striped volumes, the server family of Windows 2000 also supports fault tolerant volume types. The pope then assumes a place of honor as the rest of the Cardinals wait in turn to offer their first "obedience" ("adoratio"), and to receive his blessing. It also requires that one or more domain controllers exist to hold the Active Directory database and provide Active Directory directory services. Donning the appropriate vestments and re-emerging into the Sistine Chapel, the new pope is given the "Fisherman's Ring" by the Cardinal Camerlengo, whom he either reconfirms or reappoints. It requires that a DNS service that supports SRV resource records be installed, or that an existing DNS infrastructure be upgraded to support this functionality. The new pope is led through the "Door of Tears" to a dressing room in which three sets of white Papal vestments ("immantatio") await: small, medium, and large.

Active Directory can only be installed on a Windows 2000 Server, Advanced Server or Datacenter Server computer, and cannot be installed on a Windows 2000 Professional computer. The Dean then asks, "By what name shall you be called?" The new pope then announces the regnal name he has chosen for himself. Groups of trees that do not exist within the same namespace can be linked together to form forests. First he asks, "Do you freely accept your election?" If he replies with the word "Accepto," his reign as pope begins at that instant, not at the coronation ceremony several days afterward. Active Directory can organise groups of resources into a single domain and can link domains into a contiguous domain name space together to form trees. The Dean of the College of Cardinals then asks the successfully elected Cardinal two solemn questions. Active Directory Networks can vary from a small installation with a few hundred objects, to a large installation with millions of objects. At the end of the conclave that elected Pope Benedict XVI, church bells were also rung to signal that a new pope had been chosen.

This allows all of the information and computer settings about an organization to be stored in a central, organized database. (Traditionally wet straw was used to help create the black smoke, but a number of "false alarms" in past conclaves have brought about this concession to modern chemistry.) When a vote is successful, the ballots are burned alone, sending white smoke (fumata bianca) through the chimney and announcing to the world the election of a new pope. Active Directory stores information about its users and can act in a similar manner to a phone book. The ballots from an unsuccessful vote are burned along with a chemical compound in order to produce black smoke, or fumata nera. Active Directory allows administrators to assign enterprise wide policies, deploy programs to many computers, and apply critical updates to an entire organization, and is one of the main reasons why many corporations have moved to Windows 2000. Once the ballots are counted and bound together, they are burned in a special oven erected in the Sistine Chapel, with the smoke escaping through a small chimney visible from St Peter's Square. [11]. One of the most famous aspects of the papal election process is the means by which the results of a ballot are announced to the world.

The file and root information is replicated via the Microsoft File Replication Service (FRS). Balloting continues until a pope is elected by a two-thirds majority (since the promulgation of Universi Dominici Gregis the rules allow for a simple majority after a deadlock of twelve days). DFS roots that exist on a domain must be hosted on a domain controller or on a domain member server. Assuming the number of ballots matches the number of electors, each ballot is then read aloud by the presiding Cardinal, who pierces the ballot with a needle and thread, stringing all the ballots together and tying the ends of the thread to ensure accuracy and honesty. Domain-based DFS roots exist within Active Directory and can have their information distributed to other domain controllers within the domain — this provides fault tolerance to DFS. Before being read, the number of ballots are counted while still folded; if the total number of ballots does not match the number of electors, the ballots are burned unopened and a new vote is held. Standalone DFS allows for only DFS roots that exist on the local computer, and thus does not use Active Directory. The plate is then used to drop the ballot into the chalice, making it difficult for any elector to insert multiple ballots.

There can be two ways of implementing DFS on Windows 2000: through standalone DFS, or through domain-based DFS. The ballots are distributed and each cardinal elector writes the name of his choice on it and pledges aloud that he is voting for "one whom under God I think ought to be elected" before folding and depositing his vote on a plate atop a large chalice placed on the altar. A DFS root can only exist on a Windows 2000 version that is part of the server family, and only one DFS root can exist on that server. Three cardinals are chosen by lot to collect the votes of absent cardinal electors (by reason of illness), three are chosen by lot to count the votes, and three are chosen by lot to review the count of the votes. When users try to access a share that exists off the DFS root, the user is really looking at a DFS link and the DFS server transparently redirects them to the correct file server and share. The election of the pope almost always takes place in the Sistine Chapel, in a meeting called a "conclave" (so called because the cardinal electors are theoretically locked in, cum clavi, until they elect a new pope). The Distributed File System, or DFS, allows shares in multiple different locations to be logically grouped under one folder, or DFS root. Pope John Paul II abolished vote by acclamation and by selection by committee, and henceforth all popes will be elected by full vote of the Sacred College of Cardinals by ballot.

They all have advanced functionality not found in Windows 2000 Professional, among these features are support for DFS, Active Directory and advanced fault-tolerant volumes. Acclamation was the simplest procedure, consisting entirely of a voice vote, and was last used in 1621. The Windows 2000 server family consists of Windows 2000 Server, Windows 2000 Advanced Server and Windows 2000 Datacenter Server. Traditionally the vote was conducted by acclamation, by selection (by committee), or by plenary vote. The console can be accessed in one of two ways:. By the mid-Sixteenth century, the electoral process had more or less evolved into its present form, allowing for alteration in the time between the death of the pope and the meeting of the cardinal electors. The commands are limited to ones for checking and repairing the hard drive(s), repairing boot information (including NTLDR), replacing corrupted system files with fresh copies from the CD, or enabling/disabling services and drivers for the next boot. This Council decreed that the cardinal electors must meet within ten days of the pope's death, and that they must remain in seclusion until a pope has been elected; this was prompted by the three-year Sede Vacante following the death of Pope Clement IV in 1268.

It presents itself as a simple command line interface. The Second Council of Lyons was convened on May 7, 1274, to regulate the election of the pope. It is usually used, however, to recover the system from errors causing booting to fail, which would render other tools useless. Under present canon law, the pope is elected by the cardinal electors, comprising those cardinals who are under the age of 80. The Recovery Console is an application that is run from outside the installed copy of Windows and that enables a user to perform maintenance tasks that cannot be run from inside of the installed copy, or cannot be feasibly run from another computer or copy of Windows 2000. Canon law requires that if a layman or non-bishop is elected, he receives episcopal consecration from the Dean of the College of Cardinals before assuming the Pontificate. [10]. Pope Urban VI, elected 1378, was the last pope who was not already a cardinal at the time of his election.

It can also repopulate and repair all the files in the Dllcache folder. In 1059, the electorate was restricted to the Cardinals of the Holy Roman Church, and the individual votes of all Cardinal Electors were made equal in 1179. It is a command line utility that scans system files and verifies whether they were signed by Microsoft and works in conjunction with the Windows File Protection mechanism. The pope was originally chosen by those senior clergymen resident in and near Rome. The System File Checker (SFC) also comes bundled with Windows 2000. However the language of that passage of the will is not clear and others have interpreted it differently. Windows XP was the first system to integrate these two programs into one, adopting the REGEDIT.EXE behavior with the additional NT functionality. After his death it was reported that in his last will and testament he had considered abdicating in 2000 as he neared his 80th birthday.

Therefore, the only way to access the full functionality of an NT registry was with REGEDT32.EXE, which uses the older multiple document interface (MDI), which newer versions of regedit do not use. Articles on the death of John Paul II. Because REGEDIT.EXE was directly ported from Windows 98, it does not support permission editing (permissions do not exist in Windows 9x). He died on 2 April 2005 after a long period of ill-health and was buried on 8 April 2005. REGEDT32.EXE was also written for the Win32 API and requires all actions to be performed from the top menu bar. Pope John Paul II did not resign. REGEDIT.EXE was written for the Win32 API and supports right-clicking of entries in a tree view to adjust properties and other settings. Nevertheless, 332 §2 gave rise to speculation that either:.

REGEDT32.EXE represents them as a list of strings. It was widely reported in June and July 2002 that Pope John Paul II firmly refuted the speculation of his resignation using Canon 332, in a letter to the Milan daily newspaper Corriere della Sera. REGEDIT.EXE represents the three components of a value (its name, type, and data) as separate columns of a table. The Code of Canon Law 332 §2 states, If it happens that the Roman Pontiff resigns his office, it is required for validity that the resignation is made freely and properly manifested but not that it is accepted by anyone.. REGEDT32.EXE has a left-side tree view, but each hive has its own window, so the tree displays only keys. A nine-day period of mourning (novem dialis) follows after the interment of the late pope. REGEDIT.EXE has a left-side tree view that begins at "My Computer" and lists all loaded hives. Peter's Basilica.

One acts like the Windows 9x REGEDIT.EXE program and the other could edit registry permissions in the same manner that Windows NT's REGEDT32.EXE program could. The body then lies in state for a number of days before being interred in the crypt of a leading church or cathedral; the popes of the 20th century were all interred in St. Windows 2000 comes bundled with two utilities to edit the Windows registry. The deceased pope's seals are defaced, to keep them from ever being used again, and his personal apartment is sealed. Lastly, it also contains a services viewer, which allows users to view all installed services and to stop and start them on demand, as well as configure what those services should do when the computer starts. The Chamberlain cuts the ring in two in the presence of the Cardinals. It also contains a disk management snap-in, which contains a disk defragmenter as well as other disk management utilities. In other cases the ring might have been removed for medical reasons.

This contains the event viewer — a means of seeing events and the Windows equivalent of a log file, a system information viewer, the ability to view open shared folders and shared folder sessions, a device manager and a tool to view all the local users and groups on the Windows 2000 computer. But in the case of Paul VI, he had stopped wearing the ring during the last years of his reign. The main tools that come with Windows 2000 can be found in the Computer Management console (found in Administrative Tools in the Control Panel). Usually the ring is on the pope's right hand. [9]. The Cardinal Chamberlain then retrieves the Fisherman's Ring. User mode consoles can have full access granted user so they can make whatever changes they desire, can have limited access so that users cannot add to the console but they can view multiple windows in a console, or they can have limited access so that users cannot add to the console and also cannot view multiple windows in a console. A doctor may or may not have already determined that the pope had passed away prior to this point.

User mode allows consoles to be distributed with restrictions applied. It has long been claimed that a pope's death is officially determined by the Cardinal Chamberlain by gently tapping the late pope's head thrice with a silver hammer and calling his birth name three times, though this is disputed and has never been confirmed by the Vatican; there is general agreement that even if this procedure ever actually occurred, it was likely not employed upon the death of John Paul II. Author mode allows snap-ins to be added, new windows to be created, all portions of the console tree can be displayed and for consoles to be saved. Any decision that needs the assent of the pope has to wait until a new pope has been elected and takes office. In order to provide the ability to control what snap-ins can be seen in a console, the MMC allows consoles to be created in author mode or created in user mode. During the "Reading Festival", the Sacred College of Cardinals, composed of the pope's principal advisors and assistants, is collectively responsible for the government of the Church and of the Vatican itself, under the direction of the Cardinal Chamberlain; however, canon law specifically forbids the Cardinals from introducing any innovation in the government of the Church during the vacancy of the Holy See. Snap-ins can be either standalone (performs one function), or extensions (adds functionality to an existing snap-in). The current regulations regarding a papal interregnum — i.e., a sede vacante ("vacant seat") — were promulgated by John Paul II in his 1996 document Universi Dominici Gregis.

Each console can contain one or many specific administrative tools, called snap-ins. Some of the most striking examples of Papal political authority are the Bull Laudabiliter in 1155 (authorising Henry II of England to invade Ireland), the Bull Inter Caeteras in 1493 (leading to the Treaty of Tordesillas in 1494, which divided the world into areas of Spanish and Portuguese rule) the Bull Regnans in Excelsis in 1570 (excommunicating Elizabeth I of England and purporting to release all her subjects from their allegiance to her), the Bull Inter Gravissimas in 1582 (establishing the Gregorian Calendar). Each of the tools is called a console, and most consoles allow an administrator to administer other Windows 2000 computers from one centralised computer. In addition to the pope's position as a territorial ruler and foremost prince bishop of Christianity (especially prominent with the Renaissance popes like Pope Alexander VI, an ambitious if spectacularly corrupt politico, and Pope Julius II, a formidable general and statesman) and as the spiritual head of the Holy Roman Empire (especially prominent during periods of contention with the Emperors, such as during the Pontificates of Pope Gregory VII and Pope Alexander III), the pope also possessed a degree of political and temporal authority in his capacity as Supreme Pontiff. Windows 2000 introduced the Microsoft Management Console (MMC), which is used to create, save, and open administrative tools. As has been hitherto mentioned, the pope's sovereignty over the Papal States ended in 1870 with their annexation by Italy. [8] It also has support for many different locales, a list of which can be found on Microsoft's website. In 800, Pope Leo III crowned the Frankish ruler Charlemagne as Roman Emperor, a major step toward establishing what later became known as the Holy Roman Empire; from that date it became the pope's prerogative to crown the Emperor or any monarch with affiliations with the church until the crowning of Napoleon.

It supports Arabic, Armenian, Baltic, Central European, Cyrillic, Georgian, Greek, Hebrew, Indic, Japanese, Korean, Simplified Chinese, Thai, Traditional Chinese, Turkic, Vietnamese and Western European languages. Peter). Windows 2000 has support for many languages other than English. This status as a secular and civil leader was vividly displayed by Pope Leo I's confrontation with Attila in 452 and was substantially increased in 754, when the Frankish ruler Pippin the Younger donated to the pope a strip of territory which formed the core of the so-called Papal States (properly the Patrimony of St. They included several utilities designed to make the system more accessible:. Though the progressive Christianisation of the Roman Empire in the fourth century did not confer upon bishops civil authority within the state, the gradual withdrawal of imperial authority during the 5th century left the pope the senior Imperial civilian official in Rome, as bishops were increasingly directing civil affairs in other cities of the Western Empire. Microsoft made an effort to increase the usability of Windows 2000 for people with visual and auditory impairments and other disabilities. See Donation of Constantine for discussion of the broader authority the papacy has argued the Catholic Church possesses in affairs of state.

Windows 2000 also added support for iSCSI protocol. While approval is generally granted, it is at the pope's discretion. All versions of Windows 2000 support three types of dynamic disk volumes (along with basic storage): simple volumes, spanned volumes and striped volumes:. Most of these functions are performed by and through the various dicasteries of the Roman Curia, with the pope simply approving their actions prior to becoming official. Windows 2000 introduced the Logical Disk Manager for dynamic storage. He can appoint bishops to dioceses, erect and suppress dioceses, appoint prefects to the Roman dicasteries, approve or veto their acts, modify the Liturgy and issue liturgical laws, revise the Code of Canon Law, canonize and beatify individuals, approve and suppress religious orders, impose canonical sanctions, act as a judge and hear cases, issue encyclicals, and issue infallible statements on matters pertaining to faith and morals which, according to the Church, must be believed by all Catholics. [7] Also, in case of a user losing access to their key, support for recovery agents that can decrypt files has been built in to the EFS system. The pope has many powers which he exercises.

Because this is done at the file system level, it is transparent to the user. It enables each person to attain salvation through his or her free cooperation.". It then uses the symmetric key to decrypt the file. This grace comes from Christ; it is the result of his sacrifice and is communicated by the Holy Spirit. To decrypt the file, the file system uses the private key of the user to decrypt the symmetric key that is stored in the file header. For such people, salvation in Christ is accessible by virtue of a grace which, while having a mysterious relationship to the Church, does not make them formally a part of the Church but enlightens them in a way which is accommodated to their spiritual and material situation. The symmetric key that is used to encrypt the file is then encrypted with a public key that is associated with the user who encrypted the file, and this encrypted data is stored in the header of the encrypted file. Pope Pius IX stated in his encyclical Quanto conficiamur moeror (1868): "We all know that those who are afflicted with invincible ignorance with regard to our holy religion, if they carefully keep the precepts of the natural law that have been written by God in the hearts of all men, if they are prepared to obey God, and if they lead a virtuous and dutiful life, can attain eternal life by the power of divine light and grace." Pope John Paul II wrote in his encyclical Redemptoris Missio: "But it is clear that today, as in the past, many people do not have an opportunity to come to know or accept the Gospel revelation or to enter the Church...

EFS works by encrypting a file with a bulk symmetric key (also known as the File Encryption Key, or FEK), which is used because it takes a relatively smaller amount of time to encrypt and decrypt large amounts of data than if an asymmetric key cipher is used. Many popes stressed that those who are "invincibly ignorant of the Catholic religion" can still obtain salvation. As of February 2004, its encryption has not been compromised. However, this dogma has been misinterpreted by both Catholics and non-Catholics alike. EFS works in conjunction with the EFS service, Microsoft's CryptoAPI and the EFS File System Run-Time Library (FSRTL). and if separated from the Body of Christ he is not one of His members, nor is he fed by His Spirit.". It allowed any folder or drive on an NTFS volume to be encrypted transparently to the end user. The Catholic Church alone is the Body of Christ..

The Encrypting File System (EFS) introduced strong encryption into the Windows file world. Blessed John XXIII said: "Into this fold of Jesus Christ no man may enter unless he be led by the Sovereign Pontiff, and only if they be united to him can men be saved." Pope Paul VI also said: "Those outside the Church do not possess the Holy Spirit. Volume mount points and directory junctions allow for a file to be transparently referred from one file or directory location to another. This teaching is often summarized by the phrase "extra Ecclesiam nulla salus" (outside the Church exists no salvation), which has been reaffirmed by many popes throughout the centuries. Reparse points are used to implement Volume Mount Points, Directory Junctions, Hierarchical Storage Management, Native Structured Storage and Single Instance Storage. The Roman Catholic Church teaches that "it is absolutely necessary for the salvation of every creature to be united to the Roman Pontiff" (Pope Boniface VIII). Reparse points allow the object manager to reset a file namespace lookup and let file system drivers implement changed functionality in a transparent manner. It also dogmatically defined (ch.4, s.9) the doctrine of Papal infallibility, sc. such that.

Sparse files allow for the efficient storage of data sets that are very large yet contain many areas that only have zeroes. 331 defines the power of the pope as "supreme, full, immediate and universal ordinary power in the Church, and he can always freely exercise this power"). Microsoft released the third version of the NT File System (NTFS) — also known as version 5.0 — in Windows 2000; this introduced quotas, file-system-level encryption (called EFS), sparse files and reparse points. The powers of the pope are defined by the Dogmatic Constitution (ch.3, s.8) such that "he is the supreme judge of the faithful, and that in all cases which fall under ecclesiastical jurisdiction recourse may be had to his judgement" and that "the sentence of the apostolic see (than which there is no higher authority) is not subject to revision by anyone, nor may anyone lawfully pass judgement thereupon" (can. In order to improve performance on computers running Windows 2000 as a server operating system, Microsoft gave administrators the choice of optimising the operating system for background services or for applications. The Dogmatic Constitution's third chapter, "On the power and character of the primacy of the Roman pontiff," states that (s.1) "the definition of the ecumenical council of Florence, which must be believed by all faithful Christians, namely that the apostolic see and the Roman pontiff hold a world-wide primacy, and that the Roman pontiff is the successor of blessed Peter, the prince of the apostles, true vicar of Christ, head of the whole church and father and teacher of all Christian people," that (s.2) "by divine ordinance, the Roman church possesses a pre-eminence of ordinary power over every other church, and that the jurisdictional power of the Roman pontiff is both episcopal and immediate" and that "clergy and faithful, of whatever rite and dignity, both singly and collectively, are bound to submit to this power by the duty of hierarchical subordination and true obedience, and this not only in matters concerning faith and morals, but also in those which regard the discipline and government of the church throughout the world.". Users have the option of dumping the first 64KB of memory to disk (the smallest amount of memory that is useful for debugging purposes, also known as a minidump), a dump of only the kernel's memory or a dump of the entire contents of memory to disk, as well as write that this event happened to the Windows 2000 event log. The Dogmatic Constitution's second chapter, "On the permanence of the primacy of blessed Peter in the Roman pontiffs", states that (s.1) "that which our Lord Jesus Christ [...] established in the blessed apostle Peter [...] must of necessity remain forever, by Christ's authority, in the church which, founded as it is upon a rock, will stand firm until the end of time," that (s.3) "whoever succeeds to the chair of Peter obtains by the institution of Christ Himself, the primacy of Peter over the whole church", and that (s.5) "if anyone says that it is not by the institution of Christ the Lord Himself (that is to say, by divine law) that blessed Peter should have perpetual successors in the primacy over the whole church; or that the Roman pontiff is not the successor of blessed Peter in this primacy: let him be anathema.".

[6] Microsoft recognised that the infamous Blue Screen of Death (or stop error) could cause serious problems for servers that needed to be constantly running and so provided a system setting that would allow the server to automatically reboot when a stop error occurred. The first chapter of this document is entitled "On the institution of the apostolic primacy in blessed Peter", and states that (s.1) "according to the Gospel evidence, a primacy of jurisdiction over the whole church of God was immediately and directly promised to the blessed apostle Peter and conferred on him by Christ the Lord" and that (s.6) "if anyone says that blessed Peter the apostle was not appointed by Christ the Lord as prince of all the apostles and visible head of the whole church militant; or that it was a primacy of honour only and not one of true and proper jurisdiction that he directly and immediately received from our Lord Jesus Christ Himself: let him be anathema.". This prevents programs (with the exception of Microsoft's update programs) from replacing critical Windows system files and thus making the system inoperable. The status and authority of the pope in the Catholic Church was dogmatically defined by the First Vatican Council in its Dogmatic Constitution of the Church of Christ (July 18, 1870). As well as these features, Microsoft introduced a new feature to protect critical system files, called Windows File Protection (WFP). The ommission of the tiara in the pope´s personal coat of arms, however, did not mean the total disappearence of it from papal heraldry, since the coat of arms of the Holy See was kept unatered. Windows 2000 also has several standard system utilities included as standard. The distinctive feature of the crossed keyes behind the shield was maintained.

Certain features are common across all versions of Windows 2000 (both Professional and the Server versions), among them being NTFS 5, the Microsoft Management Console (MMC), the Encrypting File System (EFS), dynamic and basic disk storage, usability enhancements and multi-language and locale support. With the recent election of Benedict XVI in 2005, his personal coat of arms eliminated the papal tiara; a mitre with three horizontal lines is used in its place, with the pallium, a papal symbol of authority, more ancient than the tiara, the use of which is also granted to metropolitan archbishops as a sign of communion with the See of Rome, was added underneath of the shield. The lowest level drivers are either legacy Windows NT device drivers that control a device directly or can be a PnP hardware bus. This flag was first adopted in 1808, whereas the previous flag had been red and gold, the traditional colours of the Pontificate. The Windows Driver Model (WDM) exists in the intermediate layer and was mainly designed to be binary and source compatible between Windows 98 and Windows 2000. The flag most frequently associated with the pope is the yellow and white flag of Vatican City, with the arms of the Holy See ("Gules, two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or") on the right hand side in the white half of the flag. Kernel mode drivers exist in three levels: highest level drivers, intermediate drivers and low level drivers. Though unique for each pope, the arms are always surmounted by the aforementioned two keys in saltire (i.e., crossed over one another so as to form an X) behind the escutcheon (one key silver and one key gold, tied with a red cord), and above them a silver triregnum with three gold crowns and red infulae, or the red strips of fabric hanging from the back over the shoulders when worn ("two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or").

[5] The microkernel is also responsible for initialising device drivers at bootup that are necessary to get the operating system up and running. In heraldry, each pope has his own Papal Coat of Arms. The microkernel often interfaces with the process manager. Main article: Papal regalia and insignia.. The microkernel sits between the HAL and the executive and provides multiprocessor synchronization, thread and interrupt scheduling and dispatching, trap handling and exception dispatching. Other important passages include Luke 22: 31 – 32, John 1: 42, and John 21: 15 – 17. The HAL includes hardware specific code that controls I/O interfaces, interrupt controllers and multiple processors. Peter:.

It was designed to hide differences in hardware and therefore provide a consistent platform to run applications on. Chief among these passages is Matthew 16: 18 – 19, wherein Jesus Christ says to St. The Windows 2000 Hardware Abstraction Layer, or HAL, is a layer between the physical hardware of the computer and the rest of the operating system. The Roman Catholic Faith maintains that the institution of the Papacy has a biblical basis, and cites certain key passages in support of this contention. It contains various components, including:. As such, between 1309 and 1378 the popes lived in Avignon (the Avignon Papacy), a period often called the Babylonian Captivity in allusion to the Biblical exile of Israel. It deals with I/O, object management, security and process management. The pope derives his Pontificate from being Bishop of Rome but is not required to live there; according to the Latin formula ubi Papa, ibi Curia, wherever the pope resides is the central government of the Church, provided that the pope is Bishop of Rome.

The executive interfaces with all the user mode subsystems. Consequently Rome has traditionally occupied a central position in the Catholic Church, although this is not necessarily so. The kernel mode stops user mode services and applications from accessing critical areas of the operating system that they should not have access to. Peter (see Apostolic Succession). Kernel mode in Windows 2000 has full access to the hardware and system resources of the computer. The name "Holy See" (also "Apostolic See") is in ecclesiastical terminology the ordinary jurisdiction of the Bishop of Rome (including the Roman Curia); the pope's various honours, powers, and privileges within the Catholic Church and the international community derive from his Episcopate of Rome in lineal succession from the Apostle St. It consists of a security subsystem (grants/denies access and handles logons), workstation service (helps the computer gain network access) and a server service (lets the computer provide network services). It is the pope's ecclesiastical jurisdiction (the Holy See) and not his secular jurisdiction (Vatican City) which conducts international relations; for hundreds of years, the pope's court (the Roman Curia) has functioned as the government of the Catholic Church.

The integral subsystem looks after operating system specific functions on behalf of the environment subsystem. The former Papal summer palace, the Quirinal Palace, has subsequently been the official residence of the Kings of Italy and President of the Italian Republic. There are three main environment subsystems:. Historically the official residence of the pope was the Lateran Palace, donated by the Roman Emperor Constantinus I. These applications, however, run at a lower priority than kernel mode processes. He also possesses a summer palace at Castel Gandolfo (situated on the site of the ancient city-state Alba Longa). The environment subsystem was designed to run applications written for many different types of operating systems. The pope's official seat is the Basilica di San Giovanni in Laterano, and his official residence is the Palace of the Vatican.

Two subsystems make up the user mode layer of Windows 2000: the environment subsystem and the integral subsystem. John Paul II. User mode in Windows 2000 is made of subsystems capable of passing I/O requests to the appropriate kernel mode drivers by using the I/O manager. (His Holiness), as in H.H. All user mode applications access system resources through the executive which runs in kernel mode. Writing informally, pious Catholics will often use the abbreviation H.H. Such programs are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external devices. This title, however, was not abandoned altogether: the pope is still refered to as "Dominum Apostolicum" in the Latin version of the Litany of the Saints, a solemn Catholic prayer, and in some translations of it.

The user mode refers to the mode in which user programs are run. Other titles used in some official capacity include Summus Pontifex ("Highest Pontiff"), Sanctissimus Pater and Beatissimus Pater ("Most Holy Father" and "Most Blessed Father"), Sanctissimus Dominus Noster ("Our Most Holy Lord"), and, in the Medieval period, Dominus Apostolicus ("Apostolic Lord"). Windows 2000 is a highly modular system that consists of two main layers: a user mode and a kernel mode. Bishop and Servant of the Servants of God"), the latter title dating to the time of Pope Gregory I the Great. The worms have also had political consequences as many companies in several countries started to call for government action to prevent further damages from Windows worms. Episcopus Servus Servorum Dei ("NN. In August 2003, two major worms named the Sobig worm and the Blaster worm began to attack millions of Microsoft Windows computers, resulting in the largest down-time and clean-up cost ever. Bishop of the Catholic Church"), while the heading is NN.

Code Red and Code Red II were famous (and highly visible to the worldwide press) computer worms that exploited vulnerabilities of the indexing service of Windows 2000's Internet Information Services (IIS). Episcopus Ecclesia Catholicae ("NN. Several notable security flaws have been found in Windows 2000. The signature of Papal bulls is customarily NN. The only elements of the Windows project which were included in Windows 2000 were the ability to upgrade from Windows 95 or Windows 98, and support for the FAT32 file system. Max." or "P.M." (abbreviation of the ancient title Pontifex Maximus, literally "Greatest Bridge-maker", but usually translated "Supreme Pontiff"). Windows Me was released as a substitute, and the Neptune project was forwarded to the production of Whistler (Windows XP). VI"), the "PP." standing for Papa ("Pope") (or, according to unofficial sources, Pater Patrum, "Father of Fathers"), and his name is frequently accompanied in inscriptions by the abbreviation "Pont.

However, the project lagged in production time – and only one alpha release was built. x" (e.g., Pope Paul VI signed his name as "Paulus PP. Windows Neptune started development in 1999, and was supposed to be the home-user edition of Windows 2000. PP. Microsoft has replaced Windows 2000 Server products with Windows Server 2003, and Windows 2000 Professional with Windows XP Professional. The pope's signature is usually in the format "NN. Windows 2000 has since been superseded by newer Microsoft operating systems. This full title is rarely used.

Microsoft phased out all development of their Java Virtual Machine (JVM) from Windows 2000 in Service Pack 3. The title "Pope" is an informal one meaning "papa" (meaning "father"); the formal title of the pope is "Bishop of Rome, Vicar of Christ, Successor of Peter, Prince of the Apostles, Supreme Pontiff, Patriarch of the West, Primate of Italy, Archbishop and Metropolitan of the Roman Province, Sovereign of the State of the Vatican City, and Servant of the Servants of God". Microsoft has stated that they will not release a Service Pack 5, but instead, have offered an "Update Rollup" for Service Pack 4. He is styled "Your Holiness" (Sanctitas Vestra) and is frequently referred to as the Holy Father. Microsoft released Service Pack 1 (SP1) on August 15, 2000, Service Pack 2 (SP2) on May 16, 2001, Service Pack 3 (SP3) on August 29, 2002 and its last Service Pack (SP4) on June 26, 2003. In canon law, the Catholic Pope is referred to as the Roman Pontiff (Pontifex Romanus). [3] On September 29, 2000, Microsoft released Windows 2000 Datacenter. .

Novell, however, was not so impressed with Microsoft's new directory service architecture as they found it to be less scalable or reliable than their own Novell Directory Services (NDS) technology. Pope Benedict XVI is the second non-Italian (after John Paul II) to be elected to the pontificate since Adrian VI, who was pope briefly in 1522-23, and is the first German to take the seat since the eleventh century (Adrian VI may be considered both German and Dutch due to his German ancestry and birth in what would eventually become part of the Netherlands). [2] The public received the full version of Windows 2000 on February 17, 2000 and the press immediately hailed it as the most stable operating system Microsoft had ever released. He succeeds the late John Paul II, who was elected at the age of 58 in 1978. From here Microsoft issued three release candidates from between July to November 1999 and finally released the operating system to partners on December 12, 1999. The current pope is Benedict XVI (born Joseph Alois Ratzinger), who was elected at the age of 78 on 19 April 2005. The first beta for Windows 2000 was released on September 27, 1997 and several further betas were released until Beta 3 which was released on April 29, 1999. Although the document on which the territorial powers of the Pontificate was based — the so-called Donation of Constantine — was proved a forgery in the 15th century, the Papacy retained sovereign authority over the Papal States until the Italian Unification of 1870; a final political settlement with the Italian government was not reached until the Lateran Treaties of 1929.

[1] It was also the first Windows version that was released without a code name, though Windows 2000 Service Pack 1 was codenamed "Asteroid" and Windows 2000 64-bit was codenamed "Janus" (not to be confused with Windows 3.1, which had the same codename). Prior to 1870, the pope's temporal authority extended over a large area of central Italy, the territory of the Papal States that was formally known as the "Patrimony of St Peter". Originally called Windows NT 5, Microsoft changed the name to Windows 2000 on October 27th, 1998. In addition to his service in this spiritual role, the pope is also head of state of the independent sovereign State of the Vatican City, a city-state and nation entirely enclaved by the city of Rome. Windows 2000 originally descended from the Microsoft Windows NT operating system product line. The Patriarchs of some Oriental Orthodox Churches are also called "Pope" by courtesy. . Previous Patriarchs of Rome are called "Popes" by courtesy.

Unattended installations rely on the use of answer files to fill in installation information, and can be performed through a bootable CD using Microsoft Systems Management Server (SMS), by the System Preparation Tool (Sysprep). The first Patriarch of Rome to bear the title of "Pope" was Pope Boniface III in 607, the first Bishop of Rome to assume the title of "universal Bishop" by decree of Emperor Phocas. Windows 2000 can be installed and deployed to an enterprise through either an attended or unattended installation. Vicar of Christ is more appropriate to the Pope, as he takes the place of Jesus as the visible head of the Church; he succeeds Peter in this office. The Windows 2000 Server family has enhanced functionality, including the ability to provide Active Directory services (a hierarchical framework of resources), Distributed file system (a file system that supports sharing of files) and fault-redundant storage volumes. Early bishops occupying the See of Rome were designated vicar (representative) of Peter; for later popes the more authoritative vicar of Christ was substituted; this designation was first used by the Roman Synod of AD 495 to refer to Pope Gelasius I, an advocate of papal supremacy among the patriarchs. Dynamic disk storage allows different types of volumes to be used. Paul were martyred at Rome).

All versions of the operating system support the Windows NT filesystem, NTFS 5, the Encrypted File System (EFS), as well as basic and dynamic disk storage. Peter and St. Support for people with disabilities has also been improved by Microsoft across their Windows 2000 line, and they have included increased support for different languages and locale information. The office of the Pope is called the Papacy; his ecclesiastical jurisdiction is called the Holy See (Sancta Sedes in Latin) or Apostolic See (this latter, on the basis that both St. All versions of Windows 2000 have common functionality, including many system utilities such as the Microsoft Management Console (MMC) and standard system management applications such as a disk defragmentation utility. Peter as Bishop of Rome and head of the Roman Catholic Church. The kernel mode provides unrestricted access to system resources and facilitates the user mode, which is heavily restricted and designed for most applications. The Pope (from Greek: pappas, father; from Latin: papa, Papa, father) is the successor of St.

Windows 2000 is classified as a hybrid-kernel operating system, and its architecture is divided into two modes: user mode and kernel mode. a properly manifested legal instrument had already been drawn up that put into effect his resignation in the event of his incapacity to perform his duties. Additionally, Microsoft offers Windows 2000 Advanced Server- Limited Edition, which released in 2001 and runs on 64-bit Intel Itanium microprocessors. Pope John Paul II would have resigned as his health failed, or. Windows 2000 comes in four versions: Professional, Server, Advanced Server, and Datacenter Server. The use of the sedia gestatoria and of the flabella was discontinued by Pope John Paul II, with the former being replaced by the so-called Popemobile. It is part of the Microsoft Windows NT line of operating systems and was released on February 17, 2000. One of the most familiar (and now discontinued) trappings of the Papacy was the sedia gestatoria, a mobile throne carried by twelve footmen (palafrenieri) in red uniforms, accompanied by two attendants bearing flabella (fans made of white ostrich-feathers).

Windows 2000 (also referred to as Win2K, W2K or Windows NT 5.0) is a preemptible and interruptible, graphical, business-oriented operating system that was designed to work with either uniprocessor or symmetric multi-processor (SMP) 32-bit Intel x86 computers. The umbracullum (better known in the Italian form ombrellino) is a canopy or umbrella (consisting of alternating red and gold stripes). Approximately 1 GB of available disk space. Peter in a boat casting his net, with the name of the reigning pope around it. 256 MB of RAM - up to 64 GB is supported in one machine. The Fisherman's Ring, a gold ring decorated with a depiction of St. A Pentium-class CPU at 400 MHz or higher - up to 32 are supported in one machine. The silver key symbolises the power to bind and loose on Earth, and the gold key the power to bind and loose in Heaven.

Its system requirements are normal, but are compatible with vast amounts of power:

    . The "Keys to the Kingdom of Heaven", the image of two keys, one gold and one silver. As with Advanced Server, it supports clustering, failover and load balancing. The pallium (a circular band of fabric about two inches wide, worn over the chasuble about the neck, breast and shoulders and having two twelve-inch-long pendants hanging down in front and behind, ornamented with six small, black crosses distributed about the breast, back, shoulders, and pendants). Windows 2000 Datacenter Server is a variant of the Windows 2000 Server that is designed for large businesses that move large quantities of confidential or sensitive data frequently via a central server. Staff topped by a crucifix, a custom established before the 13th century. It has support for TCP/IP load balancing and enhanced two-node server clusters based on the Microsoft Cluster Server (MSCS) in the Windows NT Server 4.0 Enterprise Edition. In liturgical ceremonies popes wear an episcopal mitre (an erect cloth hat).

    It offers clustering infrastructure for high availability and scalability of applications and services, including main memory support of up to 8 gigabytes (GB) on Page Address Extension (PAE) systems and the ability to do 8-way SMP. The "triregnum" also called the "tiara" or "triple crown"; recent popes have not, however, worn the triregnum though it remains the symbol of the Papacy and has not been abolished. Windows 2000 Advanced Server is a variant of Windows 2000 Server operating system designed for medium-to-large businesses. Furthermore, Windows 2000 introduced a DNS server which allows dynamic registration of IP addresses. This also provided a purely transitive-trust relationship between Windows 2000 domains in a forest (a collection of one or more Windows 2000 domains that share a common schema, configuration, and global catalogue, being linked with two-way transitive trusts).

    Additionally, Microsoft integrated Kerberos network authentication, replacing the often-criticised NTLM authentication system used in previous versions. A significant component of the server products is Active Directory, which is an enterprise-wide directory service based on LDAP. Windows 2000 Server products share the same user interface with Windows 2000 Professional, but contain additional components for running infrastructure and application software. It supports up to two processors, and can address up to 4 GBs of RAM.

    It offers greater security and stability than many of the previous Windows desktop operating systems. It is the basic unit of Windows 2000, and the most common. Windows 2000 Professional was designed as the desktop operating system for businesses and power users. Should a disk fail in the array, the parity blocks from the surviving disks are combined mathematically with the data blocks from the surviving disks to reconstruct the data on the failed drive "on-the-fly" (this works with various levels of success).

    RAID-5 volumes: a RAID-5 volume consists of multiple disks, and it uses block-level striping with parity data distributed across all member disks. Mirrored volumes are also known as RAID-1. This means that if one disk fails, the data can be totally recovered from the other disk. Mirrored volumes: the volume contains several disks, and when data is written to one it is mirrored to the other disks.

    However, the console can then only be used if the system boots to the point where NTLDR can start it. Installing the Recovery Console via Winnt32.exe, with the /cmdcons switch. Starting from the Windows 2000 CD, and choosing to enter the Recovery Console instead of continuing with setup, or. SoundSentry: designed to help users with auditory impairments, Windows 2000 will show a visual effect when a sound is played through the sound system.

    High contrast theme: to assist users with visual impairments. Narrator: Microsoft Narrator assists users with visual impairments with system messages, as when these appear the narrator will read this out via the sound system. On screen magnifier: assists users with visual impairments by magnifying the part of the screen they place their mouse over. Normally the modifier key must remain pressed down to activate the sequence.

    StickyKeys: makes modifier keys (ALT, CTRL and SHIFT) become "sticky" — in other words a user can press the modifier key, release that key and then press the combination key. SerialKeys: gives Windows 2000 the ability to support speech augmentation devices. On screen keyboard: assists those who are not familiar with a given keyboard by allowing them to use a mouse to enter characters to the screen. MouseKeys: allows the cursor to be moved around the screen via the numeric keypad instead of the mouse.

    ToggleKeys: when turned on, Windows will play a sound when either the CAPS LOCK, NUM LOCK or SCROLL LOCK keys are pressed. RepeatKeys: allows users to slow down the rate at which keys are repeated via the keyboard's keyrepeat feature. BounceKeys: multiple keystrokes to one key to be ignored within a certain timeframe. SlowKeys: Windows is told to disregard keystrokes that are not held down for a certain time period.

    FilterKeys: These are a group of keyboard related support for people with typing issues, and include:

      . This allows better performance because disk read and writes are balanced across multiple disks. Striped volumes: also known as RAID-0, a striped volume stores all its data across several disks in stripes. If one disk fails, all data in the volume is lost.

      Spanned volumes: multiple disks spanning up to 32 disks. Simple volume: this is a volume with disk space from one disk. The Window Manager component of this driver is responsible for drawing windows and menus while the GDI (graphical device interface) component is responsible for tasks such as drawing lines and curves, rendering fonts and handling palettes. The display system is handled by a device driver contained in Win32k.sys.

      Power Manager: the power manager coordinates power events and generates power IRPs. PnP Manager: handles Plug and Play and supports device detection and installation at boot time. Process Manager: handles process and thread creation and termination. Virtual Memory Manager: manages virtual memory, allowing Windows 2000 to use the hard disk as a primary storage device (although strictly speaking it is secondary storage).

      IPC Manager: short for Interprocess Communication Manager, manages the communication between clients (the environment subsystem) and servers (components of the executive). [4]. Security Reference Monitor (SRM): the primary authority for enforcing the security rules of the security integral subsystem. I/O Manager: allows devices to communicate with user-mode subsystems by translating user-mode read and write commands and passing them to device drivers.

      This essentially is a resource management infrastructure service that allows Windows 2000 to be an object oriented operating system. Object manager: a special executive subsystem that all other executive subsystems must pass through to gain access to Windows 2000 resources. POSIX environment subsystem supports applications that are strictly written to either the POSIX.1 standard or the related ISO/IEC standards. OS/2 environment subsystem supports 16-bit character-based OS/2 applications and emulates OS/2 1.3 and 1.x, but not 2.x or later OS/2 applications.

      Win32 subsystem runs 32-bit Windows applications and also supports Virtual DOS Machines (VDMs), which allows MS-DOS and 16-bit Windows 3.x (Win16) applications to run on Windows.
