Identify licensing requirements for Terminal Server

Terminal Services requires each device that initiates a Terminal Services session to be licensed, either with a Windows 2000 license or a Terminal Services Client Access License. Terminal Services also requires a license server, which is a computer on which the Terminal Services Licensing service is enabled. The three types of licenses include:
  1. Windows 2000 Server License: This license is included with the purchase of the server product. With Terminal Services, you typically choose the Per Seat licensing mode.
  2. Windows 2000 Server Client Access License: This license is required for each computer or Windows-based Terminal connecting to the server. Windows 2000 Server Client Access Licenses permit clients to use services that the operating system provides, such as file and print services.
  3. Windows 2000 Terminal Services Client Access License: This license is required for each computer or Windows-based Terminal connecting to a server running Terminal Services. Windows 2000 Professional includes one Terminal Services Client Access License to use for remote administration; it should not be used to run applications.

Guidelines for license server

Guidelines for license server
License server: stores all Terminal Services licenses that have been installed for a group of Terminal Servers and tracks the licenses that have been issued. Terminal Services Licensing allows Terminal Services to obtain and manage its Client Access Licenses, thus simplifying the task of license management for the system administrator.

  1. Terminal Services Internet Connector License: This license is used to allow anonymous use of a Terminal Server by non-employees across the Internet on a concurrent basis.
  2. Client Access: This license is used to allow anonymous use of a Terminal Server by non-employees across the Internet on a concurrent basis.
  3. Built-in: Clients that are running the Windows 2000 operating system are automatically licensed as Terminal Services Clients.
  4. Temp: When a Terminal Server requests a license and the license server has none to give, it will issue a temporary license. The license server will track the issuance and expiration of these temporary licenses.

The Terminal Services Licensing service is a component service of Windows 2000 Server, Windows 2000 Advanced Server, and Microsoft Windows 2000 Datacenter Server, and is a separate entity from Terminal Services. Terminal Services Licensing is used only with Terminal Services in Application Server mode. The license server must be discoverable by the Terminal Servers. For a Windows 2000 domain, this means the license server must be deployed on a domain controller. The Terminal Server will discover the license server by enumerating its domain controllers and checking for Terminal Services Licensing. For a workgroup, or a Windows NT 4.0 domain, the license server may be deployed on the Terminal Server or any member server. In this scenario, Terminal Servers will locate the available license server through broadcast. It is also possible to deploy a license server in a Windows 2000 network on a site basis. This approach, known as the enterprise licensing configuration, can be selected at installation. It will allow any Terminal Servers in the same physical site to discover the Terminal Services Licensing service, even across domain boundaries. This configuration does not support discovery from remote sites within the network. There are no hardware requirements for a license server other than those required to install Windows 2000 Server. Terminal Services Licensing requires approximately 5 MB of hard disk space per 6,000 client licenses issued. Memory usage is under 10MB of RAM, whether idle or active.
