Licensing Manage must br running for Terminal Services (TS)unless you are in the 120 day evaluation period.
Info about licensing TS: 1.) Each computer connecting must have it's own Windows CAL. 2.) Each computer connecting must have a TS CAL unless it is Windows XP Pro or 2000 Pro. Both of the pro versions include a CAL for connecting to TS. Win XP Home, Win 9X and any other O.S. require a license. 3.) Remember that, for most software vendors, you must but a software license for every computer connecting to TS and using the software. e.g. If you have MS Office on TS you need to buy an Office license for every computer that connects to it. If the client computer has Office on it already that computer will not require an additional license.
Check with all your software vendors and make sure that you will not be violating their software agreements by leting X number of people use their software on a TS
If you are using it in Admin mode you don't need extra license but that's only for administering the server remotely and only limited to 2 logins at one time.
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.
