I am having trouble connecting to my brother's Mac Mini from my iMac. We are both connected through a wired connection running to my Airport Extreme Base Station (Fast Ethernet). I can see his Mac Mini in the leopard finder sidebar but I can not connect to him. It just hangs and looks like its trying to connect. Any idea what could be wrong? When I click on the "Connect As" or "Share Screen" buttons, nothing happens. EDIT: He can mount my computer but I can't his.
