ERROR_DS_DRA_DN_EXISTS
ERROR_DS_DRA_DN_EXISTS (8441) is an Active Directory replication error. The destination already contains an object with the distinguished name that the replication operation is trying to create or reconcile. This can be a conflict, stale state, or a result of divergent object history.
What to check
- Identify the conflicting DN and compare its object GUID, creation state, and replication metadata on both partners.
- Avoid resolving the conflict by manually renaming or deleting the object before establishing which replica is authoritative.
- Check for related object-name collisions or lingering-object events in the Directory Service log.
