“OFFLINE” DCs

– 3 site W2K server single domain model. Master went down… Tried restore.. bunch of crap.. restore didn’t work. Took DC1 off of network.. went to site 2 DC2… took possession.. set credentials… errors but it finally worked. Wouldn’t replicate w/DC3.. no users can still log on. It seems that DC2 came back..kind of but everytime we try to do something on DC2 it says we don’t have administrative rights or the domain is nonexistant… even though AD is right there in front of us. If we close down and restart we have to manually connect to the DC…it won’t let us connect to the forest…. ANY IDEAS????
