What This Code Means
0xC0000133 is commonly associated with Kerberos authentication failing due to clock skew. Time synchronization is required for ticket validation; if the client time differs too much from the domain controller, authentication can be rejected.
Where Users Usually See This Code
- Domain logon failures
- Kerberos-based SSO failures
Why This Code Appears
- Incorrect time/time zone on the client
- NTP/time sync not functioning
- VM time drift
What Typically Happens Next
- Users cannot authenticate until time is corrected
What This Code Is Not
- It is not a password mistake
- It is not an account disable indicator
Troubleshooting Checklist
- □ Verify system time and time zone
- □ Restore time synchronization (domain time/NTP)
- □ Check virtualization host time configuration
Notes And Edge Cases
Time skew issues can break many services at once; fixing the underlying time source is the durable solution.
