windows-server-2008-r2

We recently had to upgrade our servers from Win 2008 R2 Standard to Enterprise. The upgrade method was DISM. After the upgrade, a lot of weird things started to happen.

Though Windows says it's been properly activated, we lost 1) RDP settings (disappeared from the Remote Setting tab of Properties of My Computer) 2) The option to join a domain is grayed out 3) The server had to 2 physical processors 12 cores each. Now, task manager or windows sees only 1 processor (or only 12 cores) 4) the amount of physical ram on this sever is 32 GB (Windows reports only 4 GB are usable)

Has anyone encountered this before ? Thanks Ravi
