I feel so dumb, prob something simple, i am making hard!! Please Help

Well, I need a way to “see” who is connected though active directory users and computers, each user has a roaming profile. Someone told me to go to terminal server management; I see my remote desktop connection but nothing else. I know this is probably a simple problem, and I have done many searches, but its just one of those things I can?t find. Thanks for your help
