The way that a license name is displayed is based upon the method that you used to install and activate the client license pack on the server.

Windows 2000 Server-Terminal Services CAL Token (Per-Device) is used when the server is configured to use the Automatic (recommended) installation method.

Windows 2000 Terminal Services Client Access License is used when the license server is configured to use the Web Browser or Telephone installation methods.

NOTE: See How do I activate a Terminal Services license server by using Terminal Server Licensing in Microsoft Windows Server 2003?
