With Terminal Server you can host applications in a central location, which saves management and deployment time and increases security because you install the applications once on a server, rather than on every desktop.
For information about using Terminal Services and other remote management tools for remote administration, see the Server Management Guide of the Microsoft Windows Server 2003 Resource Kit (or see the Server Management Guide on the Web at http://www.microsoft.com/reskit).
