All heck broke loose this afternoon. The PDC and BDC stopped communicating and Exchange 2007 was stuck in the middle. I can force AD replication from 2 to 1 but when I try from 1 to 2 I get an error that says:
"The following error occurred during and attempt to synchronize naming contect <domain> from domain controller dc1 to dc2. Replication is denied. It looked as if the PDC was not workign correctly so I tried to transfer FSMO roles to the BDC and take the PDC offline. When I did that the BDC tool the roles fine but the PDC would not let go of them, saying that if I wanted to transfer roles I would have to connect the DC's....but they are connected. When I perform a netdiag on the Exchange Server it can't find any domain conrollers.
I'm not sure what happened here, but nothing seems to be talking. I have layer 1, 2, and 3 connection but that seems to be where it stops. I am getting pummeled with userenv 1030 and 1058 errors as well as Exchange errors and warnings that there are no domain controllers online. I have reset teh kerberos passwords thinking it might be an authentication error or maybe a journal wrap of some sorts possibly. I have been going blind trying to figure this one out. Any help gets my eternal gratitude.
