STATUS_DS_RIDMGR_INIT_ERROR
RID Manager initialization failed
The RID Manager is part of the domain infrastructure that supplies unique RIDs for security principal creation. If it cannot initialize, account and computer creation can fail even if ordinary LDAP reads still work.
This is usually diagnosed on the affected domain controller with Directory Service events, FSMO role state, replication status and database health. It is not repaired by changing the name or attributes of the object that failed to be created.
What to inspect
- Check RID Manager and Directory Service startup events on the DC.
- Verify RID Master role ownership and replication of FSMO metadata.
- Confirm that the NTDS database and system volume are healthy before forcing role recovery.
