Terminal Server has its own method for licensing clients that log on to terminal servers, separate from the licensing method for Microsoft® Windows Server 2003 family operating system clients. When a client connects to a terminal server, the terminal server determines if a client access license (CAL) is needed. The terminal server then requests a CAL from the Terminal Server license server, and then the CAL is issued to the client by the terminal server. Although Terminal Server provides a licensing grace period during which no license server is required, after the grace period ends, clients must receive a valid CAL issued by a license server before they can log on to a terminal server.
