Windows Server 2008 for Legacy Servers
Windows Server 2008 for Legacy Servers (shortly Windows 2008 FLS) is an OS based on a Windows Server 2003 SP2.
It was created after release of Windows Server 2008. The main goal was to create an OS for legacy servers that can't upgrade to Windows Server 2008 for some reason.
Windows 2008 FLS includes only main components for server from original release of Windows Server 2008.
== Contents ==
* 1New kernel number
* 2Unreleased R2
* 3Editions
* 4"Longhorn FLP for Servers"
* 5"Uranium Server"
== New kernel number ==
Windows 2008 FLS includes a new kernel number: 5.3, although it was based on Windows Server 2003, which has 5.2 kernel number. Perhaps this is due to the fact that Microsoft has integrated components that are not compatible with Windows Server 2003, and for convenience a new codebase was created.
== Unreleased R2 ==
Microsoft wanted to release R2 for Windows 2008 FLS, but this idea was cancelled. It was mentioned in the Microsoft docs that R2 was supposed to bring new editions like Enterprise and Datacenter, which were originally planned to be released in the original Windows 2008 FLS release.
The reason to cancel R2 is still unknown, and Microsoft has not given official responses.
== Editions ==
Windows 2008 FLS has 2 editions:
* Standard
* Web Edition
Two more editions were planned: Enterprise and Datacenter, but they were canceled during the development.
== "Longhorn FLP for Servers" ==
The earliest codename of Windows 2008 FLS. There are guesses that Windows Vista (aka Longhorn) should have had a stripped-down version like Windows Fundamentals for Legal PCs. The same guesses with Windows Server 2008, but in this case, that OS must have a 6.0 kernel number. However, this information is not official, docs confirming this have not yet been leaked to the Internet, and there haven't been official responses from Microsoft, and there will not be (maybe).
== "Uranium Server" ==
Third codename of Windows 2008 FLS. There are guesses that Microsoft was developed "Uranium Client" (aka client counterpart of Uranium), but this is contradicted by the official response from Microsoft: "We never developed the Uranium Client, and Uranium Server is nothing more than a codename along with 'Windows 2002' and 'Windows 2002 Server' which was the codename for Windows Server 2003".
