Have a 2003 Domain. Setup a 2008R2 Server and joined it to the domain, then did dcpromo, after updating the schema to support 2008 R2. DCPromo ran fine, went to reboot and came back up ready to login. I log in and it comes to a blank blue screen, can't actually do anything. I can reboot into safe mode, works fine, back to normal, no luck. So I decided to build up another VM and try again. Same process, same result... No matter what I try, the servers will not log into a usable desktop. No errors in the event log. The 2003 R2 Domain controller is able to log in just fine. Any thoughts? Thanks in advance!
