Editing Windows Server 2003 (section)

==Overview==
Windows Server 2003 is the follow-up to Windows 2000 Server, incorporating compatibility and other features from [[Windows XP]]. Unlike Windows 2000, Windows Server 2003's default installation has none of the server components enabled, to reduce the [[attack surface]] of new machines. Windows Server 2003 includes compatibility modes to allow older applications to run with greater stability. It was made more compatible with [[Windows NT 4.0]] domain-based networking. Windows Server 2003 brought in enhanced Active Directory compatibility and better deployment support to ease the transition from Windows NT 4.0 to Windows Server 2003 and [[Windows XP]] Professional.<ref>{{Cite web |last=Petri |first=Daniel |date=2009-01-08 |title=Overview of Windows Server 2003 – Standard Edition {{!}} Petri IT Knowledgebase |url=https://petri.com/overview_of_windows_server_2003_standard_edition/ |access-date=2023-01-14 |website=petri.com |language=en-US}}</ref>

Windows Server 2003 is the first server edition of Windows to support the [[IA64]] and [[x64]] architectures.<ref>{{Cite web |last=Team |first=Microsoft Windows Server |date=2005-04-05 |title=Windows Server 2003 SP1 and X64 Editions – A Historical Perspective |url=https://cloudblogs.microsoft.com/windowsserver/2005/04/05/windows-server-2003-sp1-and-x64-editions-a-historical-perspective/ |access-date=2023-01-14 |website=Microsoft Windows Server Blog |language=en-US}}</ref>

The product went through several name changes during the course of development. When first announced in 2000, it was known by its [[Microsoft codenames|codename]] "Whistler Server"; it was named "Windows 2002 Server" for a brief time in mid-2001, followed by "Windows .NET Server" and "Windows .NET Server 2003". After Microsoft chose to focus the ".NET" branding on the [[.NET Framework]], the OS was finally released as "Windows Server 2003".<ref>{{cite web|url=https://www.cnet.com/news/windows-servers-identity-crisis/|title=Windows Server's identity crisis|date=9 January 2003|work=[[CNET]]|publisher=[[CBS Interactive]]|access-date=16 August 2019}}</ref>

Windows Server 2003's codebase was reused for the [[development of Windows Vista]] under its codename, "Longhorn".<ref name="vista" /> Pre-reset builds of "Longhorn" were based on the Windows .NET Server Release Candidate 1 (3663) codebase, whereas post-reset builds of "Longhorn/Vista" after the development reset in 2004 are based on the works-in-progress Windows Server 2003 Service Pack 1 (3790.1232) codebase.<ref>{{Cite web |title=Information about preliminary build of post-reset Windows Vista |url=https://betawiki.net/wiki/Windows_Vista_build_3790.1232 |website=BetaWiki}}</ref>
