When installing windows terminal server on a member server, is it necessary to install a Terminal License Server on a Domain Controller even if all the clients are running Windows 2000 or XP? I thought that terminal server licenses just needed to be bought for windows 9X machines. I have a server running Terminal Services, but do not have a license server on the network. It was working fine till a couple of days ago. At this time, under Terminal Service Manager, there are no servers listed. When I change the terminal service mode to Administration mode, I still can't connect. Please help. Thank you.
