SYMPTOMS
Consider the following scenario:
 * When you configure the local computer policy on a Windows XP-based computer, you remove all the users and the groups in the Allow log on through Terminal Services Properties dialog box.
 * You add a user account in the Allow log on through Terminal Services Properties dialog box.
 * The user is not a member of the Remote Desktop Users group.

In this scenario, when you use the user account to log on to the Windows XP-based computer through terminal services for the first time, you can successfully log on to the Windows XP-based computer. After you log off from the remote desktop connection and then log on to the computer through terminal services again, you cannot log on the computer.

However, you expect the user who can log on to the computer through terminal services to be a member of the Remote Desktop Users group. Therefore, the first logon should be denied.



RESOLUTION
A hotfix is available to resolve this problem. After you apply this hotfix, the user who is not a member of the Remote Desktop Users group cannot log on to the computer through terminal services. This behavior occurs even if you add the user to the Allow log on through Terminal Services Properties dialog box.
