Verbose logs showing the problem

Suggested solution to the issue

Please implement error handling in the ValidateCredentials method that can account for errors calling LogonUser which do not indicate invalid credentials.

The relevant errors to account for are: ERROR_ACCOUNT_RESTRICTION, ERROR_INVALID_LOGON_HOURS, ERROR_INVALID_WORKSTATION, ERROR_ACCOUNT_DISABLED

As documented on the Windows Dev Center Docs.
