An optional component of Microsoft Windows 2000 Server that enables users to access the Windows 2000 desktop and run Microsoft Windows applications on remote computers and terminal devices. Terminal Services enables Windows 2000 Server to function as a terminal server and provide terminal emulation for a wide range of client computers. By moving all processing to the server, Terminal Services reduces total cost of ownership by:
In order for Terminal Services to work on a network, you must implement three components:
Graphic T-6. Terminal Services.
You can install Terminal Services during Setup or afterward using Add/Remove Programs in Control Panel. To use Terminal Services, you must install both Terminal Services and Terminal Services Licensing, and you need to specify the directory location of the licensing server database.
Once the services are installed, you can configure the security of the terminal server to allow users to remotely run multiuser applications, configure user accounts to allow them to log on to the terminal server, create user profiles and home directories if desired, and install Terminal Services client software on client computers. You can install client software either by downloading it across the network or by creating client installation disks for manual installation.
The implementation of RDP on Windows 2000 requires that TCP/IP be implemented as the underlying network transport.
By installing the Citrix MetaFrame add-on, non-Windows clients such as UNIX, Macintosh, and OS/2 Warp can also access a Windows 2000–based server running Terminal Services in order to run Windows 2000 applications.
A good rule of thumb is that a terminal server needs an additional 4 to 8 MB of RAM for each additional client it supports. Also, do not run legacy MS-DOS or 16-bit Windows on the terminal server, as this can significantly reduce the number of concurrent users that the server can support and increase the memory requirements for each connected client.
Install Terminal Services on a member server instead of a domain controller. Installation on a domain controller can affect the domain controller’s performance as a result of the additional load that Terminal Services places on server processor, memory, and network interface.
