Windows Server 2008 RC1 available on MSDN
Just go to MSDN Subscriber Downloads and fetch RC1, if you don't have a MSDN account you will have to wait another week for this release. If you're an EPiServer employee you find it at P:\Microsoft Windows 2008\RC1.
Also, RC1 of Windows Vista SP1 will be available bringing up IIS 7 to the same codebase as Windows Server 2008.
As a sidenote Windows XP SP3 also made it's way to RC1 and SP1 for Office 2007 is around the corner.
