Windows Server components[edit]

ComponentAcronymDescriptionSupported by
Windows Server domainA logical group of computers that share a central directory and user databaseAll Windows NT-based versions
Active DirectoryADA set of technologies introduced with Windows 2000 that allows administrators to assign enterprise-wide policies, deploy programs to many computers, and apply critical updates to an entire organization. Active Directory stores information and settings relating to an organization in a central, organized, accessible database. Networks can vary from a small installation with a few objects, to global-scale directories with millions of objects.
   Related topics: Active Directory Service Interfaces, Flexible single master operation, IntelliMirror, Active Directory Application Mode
Windows 2000, Windows Server 2003
Domain controllerDC, PDC, BDCA server that responds to security authentication requests (logging in, checking permissions, etc.) within a Windows Server domain. Prior to Windows 2000, a domain controller was either a Primary Domain Controller (PDC), of which there could only be one with this role; or a Backup Domain Controller (BDC). In Windows 2000 and later the concept of primary and secondary domain controllers were eliminated, partially to emphasize the multi-master replication technology available in Windows.All Windows NT-based versions
Group PolicyGP, GPOProvides centralized management of user and computer settings in an Active Directory environment. Group policy can control a target object's registry, NTFS security, audit and security policy, software installation, logon/logoff scripts, folder redirection, and Internet Explorer settings. Policy settings are stored in Group Policy Objects (GPOs), and may be linked to one or more sites, domains or organizational units.

File systems[edit]

ComponentDescriptionSupported by
File Allocation Table (FAT, FAT12, FAT16)The original file systems used with MS-DOS. The standard file systems used with Windows 1.0 through Windows 95.All versions
FAT32Extensions to FAT supporting larger disk sizes. The standard file system for Windows 98 and ME.Windows 95 OSR2, Windows 98, Windows 2000, Windows XP, Windows Server 2003, Windows Vista
NTFSStandard file system of Windows NT; supports security via access control lists, as well as file system journaling and file-system metadata. Windows 2000 added support for reparse points (making NTFS junction points and Single instance storage possible), Hard links, file compression, and Sparse files. Encryption of data is provided by Encrypting File System. Symbolic links and transactioning of file operations via Transactional NTFS are features new to Windows Vista.

Although Windows 9x operating systems cannot read or write NTFS formatted disks, they can access the data over a network if it is shared by a computer running Windows NT.

Windows NT (all versions)
ISO 9660 (CDFS)The predominant file system for CD-ROM and DVD-ROM media. Windows includes support for Joliet extensions and the ISO 9660:1999 standard. ISO 9660:1999 is supported since Windows XP.MS-DOS and Windows 9x via extensions, such as MSCDEX.EXE (Microsoft CDROM Extension), natively in Windows NT
Universal Disk Format (UDF)A file system for storing files on optical media. It is an implementation of the ISO/IEC 13346 standard (also known as ECMA-167). It is considered to be a replacement of ISO 9660. Successive versions of Windows have supported newer versions of UDF.Windows 98, Windows 2000, Windows XP, Windows Server 2003, Windows Vista
HPFSHigh-Performance File system, used on OS/2 computers. Read and write capability in Windows 95 (where it also listed network computer NTFS-formatted drives as "HPFS", even though it had no direct NTFS capabilities). HPFS write support was dropped in Windows NT 4.0 and Windows 98, and dropped altogether shortly before the release of Windows 2000.Windows 95 (Read/write), Windows 98, Windows NT (read), 3.1/3.51 (read/write/boot)

Core components[edit]

System idle processSIPA counter which measures how much idle capacity the CPU has at any given time. The process runs in the background and monitors processing bandwidth, occupied memory and the Windows virtual paging file.
Session Manager SubsystemSMSSPerforms several critical boot-time operations, such as the creation of environment variables, starting CSRSS, and performing file-copy operations that were queued up from before the system was booted (pending file rename operations). During system operation, it handles Windows File Protection and the creation of logon sessions via Winlogon.
Client/Server Runtime SubsystemCSRSSUser-mode side of the Win32 subsystem. Provides the capability for applications to use the Windows API.
Local Security Authority Subsystem ServiceLSASSResponsible for enforcing the security policy on the system. Verifies users logging on to the computer and creates security tokens.
WinlogonResponsible for handling the secure attention key, loading the user profile on logon, and optionally locking the computer when a screensaver is running. On Windows NT systems prior to Windows Vista, Winlogon is also responsible for loading GINA libraries which are responsible collecting logon credentials from the user.
Svchost.exeA generic host process name for services that run from dynamic-link libraries (DLLs). Several Svchost processes are typically present on a Windows machine, each running in a different security context, depending on what privileges the contained services require.
Windows on Windows and WOW64WoWAn abstraction layer that allows legacy code to operate on more modern versions of Windows; typically this means running 16-bit Windows applications on 32-bit Windows, and 32-bit applications on 64-bit Windows.
Virtual DOS machineNTVDMAllows MS-DOS programs to run on Intel 80386 or higher computers when there is already another operating system running and controlling the hardware. Introduced in Windows 2.1; not available in any 64-bit edition of Windows.
System startup (Windows NT)
NTLDR, IA64ldr, WinloadThe boot loader; performs basic system initialization options such as loading the hardware abstraction layer and boot-time device drivers, prior to passing control to the Windows kernel. In versions prior to Vista, NTLDR and IA64ldr also display menus to the user if multiple operating systems are defined in boot.ini, or if F8 is pressed.
Recovery ConsoleProvides the means for administrators to perform a limited range of tasks using a command line interface, primarily to aid in recovering from situations where Windows does not boot successfully.
ntdetect.comUsed during the boot process to detect basic hardware components that may be required during the boot process
Windows Boot ManagerIn Windows Vista and later operating systems, displays boot menus to the user if multiple operating systems are configured in the system's Boot Configuration Data.
Graphical subsystem
Desktop Window ManagerDWMThe compositing manager introduced in Windows Vista that handles compositing and manages special effects on screen objects in a graphical user interface
