TS Licensing is a role service that manages the Terminal Services client access licenses (TS CALs) that are required for a client to connect to a terminal server. This includes the ability to track and report both TS Per Device CALs and TS Per User CALs. If you have an existing Terminal Services license server, you can migrate the TS CALs to a new Windows Server 2008-based license server.
