ERROR_DS_DRA_NO_REPLICA

ERROR_DS_DRA_NO_REPLICA (8452) is an Active Directory replication error. The destination cannot use the selected partner for this naming context because the replica is absent or is currently being removed. The condition can be expected during a controlled topology change, but not during steady-state replication.

What to check

Confirm which domain controllers should host the naming context and whether the selected source is one of them.
Check for an in-progress application-partition, GC, or domain-controller decommissioning operation.
Review configuration-partition replication before creating new connection objects to compensate for the missing replica.

Useful command

repadmin /showrepl <DestinationDC> /all /verbose
