I recently discovered that Active Directory replication started failing about a month ago. If I attempt to Replicate Now
from the failing domain controller, I receive The following error occurred during the attempt to synchronize the domain controllers: Access is denied.
Directory Service log tells basically the same story; repeating two events
- 1061: Internal error: The directory replication agent (DRA) call returned error 5.
- 1085: Replication warning: The directory replication agent (DRA) couldn't synchronize partition DC=OUR_DOMAIN with partition on directory server big-long-guid._msdcs.OUR_DOMAIN. The error was: Access is denied
It is between two servers at a remote site. One is Windows 2003 and the other is Windows 2000; the Windows 2000 machines is experiencing the errors. The domain is older OUR_DOMAIN style.
Attempts so far:
- I disabled Kerberos service on the Windows 2000 server and restarted
- RPC and RPC locater services have expected settings
