Heres the scenario. I have a Windows 2000 Server SP-4 Active Directory Domain Controller acting as the PDC emulator. I have a second Windows NT 4 SP-6a server running as the BDC. When the Win 2k server is up and running all is well. If I take the Win 2k AD server offline for any reason no one can log onto the domain. For some reason the BDC does not authenticate users. I can synchronize between the two machines with no problem. There are no errors in the log when both machines are running. When the PDC is offline the BDC generates netlogon error events 5719 and 5722. These errors state that there is no domain controller available and that the computer accont cannot be validated.
Any one have any suggestions?
