A coworker has researched the issue and found that the KCC could take two hours to fix the replication link. We have about a half hour to go to see if this is the case. So I think your idea of letting it bake a little while longer may do the trick
 
I will post more information if the problem continues.

From that machine can you run and post the output of repadmin /showreps /v ?  Is the affected server Windows 2000 or Windows Server 2003 and what SP levels?  I assume you also did not set any preferred bridgehead settings?  You could also use ADLB.exe in report only mode to see the topology.  I am guessing that if you let it bake a little more it will correct itself.  Also what is the replication interval set on that site link, the minimum 15 minutes?

 

Thanks,

We just demoted a W2K DC in our primary site. The demotion was successful and the NTDS object associated with the DC was removed from AD Sites & Services.

In our only other site, the one domain controller is reporting replication problems. Replmon is reporting the following: The DSA Operation is unable to proceed because of a DNS lookup failure.

The error code from replmon is 8524

Over an hour has passed. The replication topology is automatic and we have all default settings in regards to replication schedules etc.

Any suggestions?

Devin
