Safe next steps
- For 8215 (ERROR_DS_CANT_MOD_OBJ_CLASS), record the domain or directory operation, server, account type, and exact message. These codes usually need administrator context.
- Have the directory administrator check service reachability, replication or object state as indicated by the message and relevant logs.
- Avoid changing domain membership, access control, or directory objects on a managed device without an approved plan.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
