What This Code Means
0xC0000070 indicates a logon restriction based on allowed workstations/hosts. Credentials may be valid, but the account policy prevents use from the current source machine.
Where Users Usually See This Code
- Windows domain logon restrictions
- RDP/SMB authentication attempts
Why This Code Appears
- Account has an “allowed workstations” list configured
- Service/account moved to a new host without policy updates
What Typically Happens Next
- Logon fails until policy allows the source host
What This Code Is Not
- It is not a password error
- It is not proof of malware
Troubleshooting Checklist
- □ Review account workstation restrictions and update if appropriate
- □ Confirm the source hostname is as expected
Notes And Edge Cases
Misconfigured workstation restrictions can block legitimate automation when hosts are replaced.
