by broadcast or that you have implemented WINS. If you are using Active Directory Users and Computers, you can right-click a user and select the Account tab and you will see the Log On To button. Click the button, and you will see the Logon Workstations screen. You can select the computer(s) for which the user is allowed access, which enables a user to log on to only the specified workstation.

If you want to prevent anyone else from logging in to the workstation, you can do so in one of two ways. First, select all the users except the user you configured above, and bring up the Properties screen. This will display the properties for all the selected users.

Select the Account tab and check the box next to Computer Restrictions. Next, click the Log On To box, and in the Logon Workstations screen select all the computers other than the one you don't want others to log in to. If you create additional users or workstations, you also need to update these settings accordingly.

Alternatively, if you use something like Windows Scripting Host for your login script, you can write a script locates the logon workstation. If it detects that the workstation is the one you don't want anyone to log in to, it immediately logs them out. I recommend the Win32 scripting site for examples of scripts with this kind of functionality.
