The partner did not recognize the connection or the replication group

The DFS Replication service failed to communicate with a partner for the replication group. The partner did not recognize the connection or the replication group configuration.

Cause

This error usually occurs when one partner attempts to establish an RPC connection with another member, but is unable to.

The problem may be intermittent and resolve itself automatically. If the two members obtain configuration data from different domain controllers, they may have mismatched configuration data due to Active Directory® replication reaching one domain controller before the other.

The service will retry the connection periodically. If this problem persists, please verify that Active Directory replication is working and that the service is able to reach a domain controller.

Upon success, Event 5004 will be displayed. If the problem persists for 8 hours, the DFS Replication service will disable the connection and display Event 5016.

Note: If the service restarts before the problem is corrected, the success event will not be displayed.

You can also run the Topology Checker from DFS Replication to review the network configuration and ensure the configuration of both members is correct.
