I have recently promoted my BDC to a PDC. Since then I'm unable to run User Manager from the BDC. I noticed many errors in the event logs as well. Clearly something's wrong with the domain synchronization between the BDC & PDC. I am running Windows NT Server 4.0 service pack 6a on both.

PDC name = W2KDC01
BDC name = NFSERVER

PDC Event Log

3/3/03     3:15:40 PM     NETLOGON     Information
None     5713     N/A     W2KDC01     The full synchronization request from the server NFSERVER completed successfully. 17 object(s) has(have) been returned to the caller.
3/3/03     3:14:40 PM     NETLOGON     Information
None     5713     N/A     W2KDC01     The full synchronization request from the server NFSERVER completed successfully. 103 object(s) has(have) been returned to the caller.
3/3/03     3:08:10 PM     NETLOGON     Information
None     5713     N/A     W2KDC01     The full synchronization request from the server NFSERVER completed successfully. 11 object(s) has(have) been returned to the caller.

These repeat every couple of minutes!

BDC Event Log

3/3/03     3:07:11 PM     NETLOGON     Warning     None
5718     N/A     NFSERVER     The full synchronization replication of the LSA database from the primary domain controller  failed with the following error: The remote procedure call failed.  
3/3/03     3:05:41 PM     NETLOGON     Warning     None
5718     N/A     NFSERVER     The full synchronization replication of the BUILTIN database from the primary domain controller  failed with the following error: The remote procedure call failed.  
3/3/03     3:04:11 PM     NETLOGON     Warning     None
5718     N/A     NFSERVER     The full synchronization replication of the SAM database from the primary domain controller  failed with the following error: The remote procedure call failed.

These repeat every couple of minutes!

I ran "NLTEST /PDC_Repl" from the PDC, status read successful.

I ran "NLTEST /Server:W2KDC01 /PDC_Repl" from the BDC, status came back:

I_NetLogonControl failed: Status = 1722 0x6ba RPC_S_SERVER_UNAVAILABLE

Any suggestions would be greatly appreciated!

Hi!

Make sure the RPC locator and RPC service is running on both PDC and BDC

Did you demote the former PDC to a BDC first?  You need to do this before you should promote a BDC to PDC.

Thanks for your quick responses......

Believe it or not, it was a network error. I swapped out the old 10mb ethernet NIC and replaced it with a 3Com 100mb NIC. Everything is syncing up fine! May have been a driver issue or just a board on the brink.

Thanks again!
