How to Fix Error Code 0xC000011A

  1. Review Logon Type in Event Viewer

  2. Check User Rights Assignments

    Changing security policies can affect system access; proceed carefully.

  3. Verify Logon Type Permissions via Command Line

    Incorrect edits to security policy can lock you out. Back up the original policy file first.

  4. Reset Local Security Policy to Default

    This step may revert other custom security settings. Note them beforehand if needed.

  5. Check Group Policy Inheritance (if domain-joined)

    Domain policy changes require admin privileges and may affect other users.

Frequently Asked Questions

What does logon type not granted mean?
It means the method you're using to log on (e.g., interactive, network, service) is not allowed for your account due to security policy restrictions.
Can this error occur with local accounts?
Yes, it can occur with local accounts if local security policies deny certain logon types for that user or group.
How do I check which logon type is blocked?
Check Event Viewer security logs for failure event 4625. The 'Logon Type' field indicates the type that was denied.
Will resetting security policy affect other settings?
Yes, resetting to default will undo any custom user rights assignments or security options you've configured. Back up your current policy first.
Is this error related to user account control (UAC)?
No, error 0xC000011A is specifically about logon type restrictions, not UAC elevation prompts.
