When I was at school I could view all the computers on the same network simply in the finder , just below devices (one of the added features in leopard). Now that I am at home, i can't see my PC and my sisters laptop, even though we are all connected to the same router. Any ideas of why this is? I am pretty sure you dont have to enable sharing on the other computers since most computers on the network at my school had sharing disabled but i could still see that they were connected to the network.
