DFS Replication errors

I have recently changed our AD replication from FRS to DFS Replication, and have noticed that one of our servers running Windows 2008 R2 is experiencing a handful of 5012 error messages each day, relating to the two other Domain Controllers (both virtual servers running Windows 2008) in one of our sites.

"The DFS Replication service failed to communicate with partner [computer name] for replication group Domain System Volume. The partner did not recognize the connection or the replication group configuration.

The service will retry the connection periodically.

Additional Information:
Error: 9026 (The connection is invalid)
Connection ID: 0B558AE8-21F2-4F33-9400-C0C643851E3C
Replication Group ID: DF1DE3C2-D1FB-450C-9285-6A227FBA2796"

Then within one or two hundredths of a second, event 5004 appears

"The DFS Replication service successfully established an inbound connection with partner [computer name] for replication group Domain System Volume."

Can anyone assist?

Hello arnold and kevinshieh,

Yes I've checked, and the errors are occurring when backups are running. The errors literally last just 0.01 or 0.02 of a second before they are replaced with 5004 events. I've run repadmin /replsum , and replication is working fine, so I will ignore these errors in future.

Thanks very much for your help.
