ERROR_DS_DS_REQUIRED
The requested operation requires a directory service, and none was available.
ERROR_DS_DS_REQUIRED is Win32 error 8478 (0x0000211E).
What to verify
Verify whether the target environment has a reachable AD DS or AD LDS service that owns the requested data or operation. Check operation and required directory role, DC locator result, and DNS SRV queries.
Likely causes
- the machine is offline or not domain-connected.
- DC discovery fails.
- the selected server is not a directory service.
- the required AD LDS instance is stopped.
Troubleshooting steps
- Collect operation and required directory role.
- Record DC locator result.
Handling, retry, and recovery
Restore directory availability or target the correct directory instance; provide an explicit offline path when the operation can be deferred.

ERROR_NO_LOGON_SERVERS is authentication-focused; this code applies more broadly to operations requiring a directory service
Example
A policy tool runs on a workgroup machine and requests domain directory data. It reports the missing directory dependency instead of searching local files for a substitute.
