STATUS_DS_SAM_INIT_FAILURE
STATUS_DS_SAM_INIT_FAILURE meaning
STATUS_DS_SAM_INIT_FAILURE has value 0xC00002E3. Security Accounts Manager initialization failed, with the nested status and event log providing the actual database, directory-service, registry, storage, or dependency error. On a domain controller this can prevent normal directory-service startup.
Evidence to collect
Preserve the nested status values, Directory Service and System event logs, database and log paths, disk health, registry hive availability, recent restore or update activity, and whether the machine is a domain controller. Do not replace the nested error with the outer NTSTATUS in telemetry.
- Preserve the exact API or command that returned this result, the caller identity, target object, complete numeric status, and the first component log that records the failure.
- Compare the failing request with a working request for it at the same subsystem boundary before applying destructive configuration changes.
Recovery and retry
Follow the event-specific Active Directory or SAM recovery procedure. For a domain controller, Directory Services Restore Mode may be required; preserve system-state backups and avoid unsupported database copying or registry edits.
