Terminal Services is a Windows 2003 component that lets you remotely access applications installed on a Windows 2003 server from a wide range of computers over most types of network connections.
Terminal Services has three components: the server, the client and the protocol by which the server communicates with the client.
When you are running Terminal Services in application server mode, all applications run on the server. The Terminal Services server sends only screen information to the client and receives input only from the mouse and keyboard.
The Terminal Services client uses thin-client technology to provide the Windows 2003 Desktop to users. The client only needs to make a connection with the server and display the visual information that the server sends.
The Remote Desktop Protocol (RDP) is automatically installed when you install Terminal Services. RDP is the only connection you need to configure in order for clients to connect to the Terminal Services server. You can configure only one RDP connection per network adapter.
1. Organizations can deploy Windows 2003 on older systems that may not have hardware supported by Windows 2003.
2. Users can continue to use their current operating system and applications.
3. Organizations can deliver Windows-based applications to a variety of desktop environments and over LANs and WANs.
4. Administrators only need to install and update one copy of an application on a server instead of on all the computers in their network.
5. Networked applications will perform better over slow network connections.
Windows 2003 Terminal Services should be set to run in application server mode. For a step-by-step procedure to enable Terminal Services, see:

Windows 2003 Terminal Services client software should be installed on every computer that needs to use Terminal Services. There are two versions of the client: 16-bit for older computers and 32-bit for newer computers. For more information about installing the client software, see:
http://windows.microsoft.com/windows2003/en/server/help/ts_cli_h_010.htm
In addition to the Windows 2000 Server CAL, you must have a Windows 2000 Terminal Services CAL to run Windows-based desktop and applications from a Windows 2000 Server, regardless of the protocol or software used to interact with applications running on the server. For more information see:
