The Terminal Services Client user interface, located in Windows 2000 Administrative Tools, allows you to log on to a remote computer from another terminal. You can use this user interface to perform remote administration and monitoring of any accessible server on the network.
For example, if you are in Toronto and you discover that a server in Tokyo is not responding and you cannot contact the on-site administrator, but the server has Terminal Services Client installed, you can remotely log on to the computer and administer it. You can restart it, run installed applications, start and stop services, and monitor performance.

Another benefit of Terminal Services Client is that you can run applications that are not installed on your computer by gaining access to a computer with Terminal Services Client that has the application you want to run.
