Yes, actually I believe it started with NT 3.51....don't hold me to that though. But, yes, There is a NT Server Terminal Services edition.
Now, what exactly do you mean with the Windows 98 PC?
Are you asking if 98 can run terminal services???
Hmmm....if the 98 client can connect, what software would i have to use? Or does microsoft supply all the utilities i need to create the client on it?
