Solution
Treat this occurrence as a lingering object condition, and do the following:
- Run the repadmin /showrepl command on the domain controller that received the error to determine which domain controller has been disconnected for longer than a tombstone lifetime.
- Remove lingering objects. Follow the instructions for removing lingering objects from the source and destination domain controllers as described in Event ID 1388 or 1988: A lingering object is detected.
- Restart replication on the destination domain controller. After you remove lingering objects, you must restart replication on the domain controller that logged the event by editing the registry setting that allows replication with a potentially out-of-date domain controller. You can also perform this procedure if you do not want to wait to remove lingering objects and you want to start replication immediately.
- Reset the registry to protect the domain controller against outdated replication. After replication has resumed on the domain controller that logged the event, reset the registry so that this domain controller continues to log events if replication is attempted with a domain controller where the last successful replication occurred longer than a tombstone lifetime ago.
Restart Replication Following Event ID 2042
To restart inbound replication on the destination domain controller following event ID 2042, you must edit the Allow Replication With Divergent and Corrupt Partner registry entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters.
Use the following procedure to change the registry entry value. This procedure does not require a restart of the domain controller to take effect.

There are no domain or forest functional requirements for this command.
ADVISORY_MODE is a test mode that logs NTDS Replication events 1938, 1946
and 1942 in the targeted domain controllers' directory service event log
identifying the lingering objects that should be removed but does not
actually remove them.
Lingering objects are removed when "repadmin /removelingeringobjects" is
run without the /advisory_mode switch. NTDS Replication events 1937, 1945
and 1939 logged on the target DC's directory services event log identify
the start, conclusion and set of objects removed from a directory
partition.
You should conceptually think of DC's in the
that you want to test or remove lingering objects from and
