This is kinda a wacky situation.
The domain was originally setup as a 2003, then someone added a 2008 DC. I want to remove the 2003 DC, so I created another one and added it to the Forest under the same Domain. All three a GC's which is strange as I thought only one could be.
How can I remove the 2003 DC, and escalate the AD to be non- windows 2000 compliant? All workstations are either XP or WIndows 7.
