DOMAIN CONFUSION

Heres what happened. I have a domain with the PDC and multiple BDC’s. Someone took a BDC and moved it to a new domain. I had to bring it back to the original domain. Now the BDC thinks it is in the 2nd domain not the one that it is supposed to be moved back into. NBTSTAT shows the domain that I don’t want. I can’t log in because it is a DC and it won’t validate me. But users can browse to it and use it. I tried to re create the secure channel between the PDC and BDC. Does anyone have any ideas?
