Required Licensing

This is off MS doc that i recevied in email from a MS LIC. expert per say. Hope this helps.
"There are 3 licenses needed when connecting to Windows Terminal Services, and you always need 3! If you do not have the three licenses listed below then your Terminal Services are not properly licensed.
1. The server license ? This may be Windows NT? Server 4.0 Terminal Server Edition or Windows 2000 Server with Terminal Services enabled in application server mode.
2. A Windows NT 4 Client Access License (CAL) or Windows 2000 CAL ? The CAL must be the same version or higher as the server being used. When using the Server CAL to support Terminal Services you may only do so in the Per Seat mode. For further details on per seat, per server and per processor licensing see the licensing brief on that topic.
3. Either a) a Terminal Server CAL (version to match or be higher than server being used) OR b) Windows NT Workstation 4.0 or Windows 2000 Professional installed on the desktop itself (version to match or be higher than server being used example ? Windows 2000 Pro can connect to Windows NT 4 TS, but Windows NT Workstation 4 would need a TS CAL or upgrade to Windows 2000 Pro to access Windows 2000 Server.).
Note: Terminal Services islicensed on a per-device basis and is not available on a per-server or per-processor use with the exception of the Terminal Services Internet Connector License explained below. Each device, whether it connects directly to the terminal server, or indirectly via another server, requires the appropriate licenses to be assigned to it."
