Windows Server 2008 R2 was generally available in Oct. 2009. Windows 2008 was generally available in May 2008. This first release was named SP1 to signify a synchronization of the Windows Server code with the code changes in Windows Vista SP1. This means the first service pack with fixes to the released Windows Server 2008 SP1 code was SP2.

Windows Server 2003 was released in May 2003. The current version is Windows Server 2003 R2 with SP2.

On July 13, 2010, Windows Server 2000 left Extended support and Mainstream support ended for Windows Server 2003 and Windows Server 2003 R2.

Now that Windows 2000 and Windows XP SP2 have reached the end of Extended support as of July 13, 2010, support has also ended for Hyper-V integration services for these OSs. Organizations using Hyper-V to run older applications that are not compatible with newer systems will still be able to do so, but with the end of support, integration services for the retired OS will not be updated and support will not be available for any issues arising from using the retired OS versions in virtual machines.
