Thank to GlenJohnson and any other people.
Microsoft License is so complicated. I know the terminal service under windows 2000 have two mode, for admin mode,it is free, for applcation server mode, we have to active license. but I don't know how the license server assign licese to workstaion. I search microsoft's website, and I know some of it.
Terminal services is perseat license mode. so every one access server through terminal server has to have license.
Our customer have one Windows 2000 server which we have already installed Terminal services and active it as application mode, and also bought 5 license for them.
When windows 2000 professional workstation connect to terminal services, it will get permanent license, but windows 9x will get temp license before we active license, and after we active license, it is changed to permanent license but it still has expire day for license, so what will happen after expired day?
