Answer : DFS replication error windows 2003 R2

Hi there,

Is this a new replication group? If so, DFS-R needs all members in the replica set to be consistent before this error will go away, and it's sometimes normal to see this event logged in the meantime.

If it's an established replication group, I'd recommend running a DFS-R health report via dfsmgmt.msc as it will tell you the exact connection object that is invalid, and you can them remove and recreate/readd the object back.
