You install Terminal Services on a Windows 2000 domain controller. You install Terminal Services Client on users' client computers. Users report that when they try to connect to the Terminal server, they receive the following error message: "The local policy of this system does not allow you to logon interactively." When you attempt to log on to the Terminal server as an administrator from a user's computer, you log on successfully. You want users to be able to log on to the Terminal server. What should you do?
