"Your Interactive Logon Privilege Has Been Disabled" Error When You Try to Log on to a Terminal Server

When you try to log on to a Microsoft Windows 2003-based terminal server, you may receive the following error message:

This issue may occur if you try to use the Guest user account to log on after you add the account to the built-in Remote Desktop Users security group. You may also receive this error if you try to log on by using any user account that is denied Read permissions to Active Directory directory service.

This behavior occurs because the domain Guest user account is denied Read permissions to their user account information in Active Directory. When an account is denied the Read permission to their Active Directory or local account information in the Windows Security Account Manager (SAM) database, the logon request is unsuccessful because the operating system cannot determine if the user has permission to log on to Windows.

To work around this issue, edit the Windows registry on the terminal server so that it causes the Winlogon process to ignore errors reading the Terminal Services Configuration data, and so that it reads the DefaultUserConfig data instead. To do so, follow these steps.

Warning: After you follow these steps, a user account whose Read permissions to the local SAM database or to Active Directory, you have intentionally removed to prevent their logon to the terminal server, will be able to log on to the terminal server.

1. Click Start, click Run, type regedit in the Open box, and then click OK.
   
   Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
