Need to raise domain functional level but cannot due to irrecoverable 2000 DC
I have a total of 3 DC's. 2 of them are windows 2003 servers and the operations master and schema master is one of the 2003 DC's. I need to raise the domain functional level to 2003 to prep for a new 2007 exchange server but cannot because it recognizes that there is a DC in the forest that is not the correct version. I would normally do a dcpromo down but the server is in a failed state. I've tried recovering it but have not had any luck. Is there any other way to remove the 2000 DC from the scenario so that I can do what needs to be done?
