I just got Remote Desktop 2 to control a few computers in another state. But, I am having difficulty getting them to connect. The included literature surprisingly doesn't cover what the "user name" and "password" are for each controlled computer (or maybe I missed it.) For those of you that have used Remote Desktop, is the "user name" and "password" that you enter when logging in to another machine that person's Mac administrator username and password? I'm confused...this should be easy, maybe I'm making it too difficult.
