I have been testing Windows Server 2008 for a long time now and have given quite a bit of feedback on that till date. After 10-12 months of testing, Microsoft's latest server operating system, Windows Server 2008 was released today for general public evaluation.
Windows Server 2008 was earlier known as Longhorn and is built on the same core as the desktop version, Windows Vista. Windows Server 2008 is a major upgrade to the server-line of operating system from Microsoft and comes nearly 4 years after the previous installment called Windows Server 2003.
You can go read, the press release here. Or if you don't like the PR blabber, then go evaluate the download from here.
Some of the interesting stuff from Windows Server 2008 are:
2.) IIS 7.0
4.) Network Access Protection
5.) Newer Clustering Features
Microsoft calls this release as Release Candidate 0 (RC0) and will have 2 other release candidates available for public testing before the final release on 27th Feb, 2008
