What This Code Means
0xC0000071 indicates the user’s password has expired per policy. Authentication will fail until the password is updated using an allowed method.
Where Users Usually See This Code
- Domain logon failures for users with expired passwords
- Service accounts that were not rotated
Why This Code Appears
- Password age policy reached
- Account not rotated/managed for long periods
What Typically Happens Next
- Login fails; user must change password
- Automations using that account fail until updated
What This Code Is Not
- It is not an account lockout (that is a different condition)
- It is not necessarily a wrong password attempt
Troubleshooting Checklist
- □ Change the password through approved channels
- □ Update stored credentials for services/scheduled tasks
Notes And Edge Cases
Service accounts with expiring passwords require credential rotation practices to avoid outages.
