STATUS_LOGON_NOT_GRANTED

The requested logon type is not granted by policy

Windows logon rights are policy-controlled. This status means the account may be valid but is not allowed to use the requested logon type, such as interactive, service, batch, or network logon.

This is different from a password failure. The diagnostic path is User Rights Assignment, domain Group Policy, and the logon type requested by the caller.

What to inspect

  • Identify the logon type and account SID.
  • Check local security policy and effective domain Group Policy for allow and deny logon rights.
  • For service accounts, verify the service logon right rather than adding the account to broad administrative groups.
