A. If you use the Active Directory Users and Computers snap-in from a remote computer (such as a Windows XP workstation), you might notice certain tabs are missing--for example, Published Certificates, Object, and Security. To display the tabs, click View, then Advanced Features. You'll also notice that the Dial-in tab is missing. Unfortunately, you can't display the Dial-in tab on a remote XP workstation that uses the Active Directory Users and Computers snap-in. If you have to edit the options on the Dial-in tab, you can use Windows 2000 Server Terminal Services to log on to a domain controller (DC) and set the options on the remote workstation from the DC.
