hey all, i'm trying to use my mac to control my windows media center, so i'm trying to get screen sharing going from my mac. i've installed tightvnc on the windows machine (the service, not just the viewer) and it should be running fine. however, when i launch screen sharing and tell it to connect to vnc://ipofwindowsmachine, it tries for about a minute and then says it couldn't establish a connection. i can, however, access the windows machine's files from my mac. does anyone have any suggestions?
