Deploying Terminal Services

Terminal Services has its own method for licensing clients that log on to Terminal servers, which is separate from the licensing method for Windows 2000 Server clients. Terminal Services licensing includes the following components: the Microsoft Clearinghouse, a license server, a Terminal server, and client licenses.
The Microsoft Clearinghouse is the database Microsoft maintains to activate license servers and to issue client license key packs to the license servers that request them. The Clearinghouse stores information about all activated license servers and client license key packs that have been issued. You access the Clearinghouse through the Licensing wizard with the Terminal Services Licensing feature.
A license server stores all Terminal Services client licenses that have been installed for a Terminal server and tracks the licenses that have been issued to client computers or terminals. A Terminal server must be able to connect to an activated license server before clients can be issued licenses. One activated license server can serve several Terminal servers simultaneously.
A Terminal server is the computer on which Terminal Services is enabled. It provides clients access to Windows-based applications running entirely on the server and supports multiple client sessions on the server. When clients log on to a Terminal server, the server validates the client license. If a client does not have a license, the Terminal server requests one for the client from the license server.
Each client computer or terminal that connects to a Terminal server must have a valid client license. The client license is stored locally and presented to the Terminal server each time the client connects to the server. The server validates the license, and then allows the client to connect.
Figure 16.1 shows the Terminal Services licensing components.

Deploying Terminal Services and Terminal Services Clients on your network requires the following licenses:
Windows 2000 Server License This license is included with the purchase of the product.
Windows 2000 Server Client Access License This is required for each device connecting to Windows 2000 Server. Client Access Licenses permit clients to use the file, print, and other network services provided by Windows 2000 Server. The Terminal Services component of Windows 2000 Server requires Per Seat licensing for the Windows 2000 Server Client Access License, except when you purchase the Windows 2000 Terminal Services Internet Connector License. The Internet Connector License is described later in this chapter.
Each client computer or terminal requires the following licenses:
Windows 2000 Terminal Services Client Access License or Windows 2000 License The Client Access License provides each client computer or Windows-based terminal the legal right to access Terminal Services on a Windows 2000 Server. For example, this license is required to start a terminal session and run Windows-based applications on the server. The Windows 2000 license permits the installation of the Windows 2000 operating system, in addition to providing the legal right to access Terminal Services on a Windows 2000 Server. The Terminal Server Client Access License is not required for clients connecting only to Terminal servers in Remote Administration mode.
In addition to the required Terminal Services licenses, two optional licenses are available: the Windows 2000 Terminal Service Internet Connector License and the Work at Home Windows 2000 Terminal Services Client Access License.
In place of the Client Access Licenses, you have the option to purchase the Windows 2000 Terminal Services Internet Connector License. This license is purchased separately as an add-on license to Windows 2000 Server. It allows a maximum of 200 concurrent users to connect anonymously to a Terminal server over the Internet. This is useful for organizations that want to demonstrate Windows-based software to Internet users without rewriting Windows-based applications as Web applications. All users who access a Terminal server with this license must not be employees.
When you use the Internet Connector License with a specific Windows 2000 Server, Terminal Services only allows anonymous client access. You cannot use the Internet Connector License with other types of Terminal Services client access licenses on the same Windows 2000 Server.
For organizations that want to use Terminal Services to provide their employees home access to the Windows 2000 desktop and 32-bit Windows-based applications, the Work at Home Terminal Services Client Access license is available through the Microsoft Volume licensing programs. For each Windows 2000 Professional or Terminal Services Client Access License you purchase, you can purchase an additional Work at Home Windows 2000 Terminal Services Client Access License.
