I have a network connection that has 4 Win XP computers linked to it. All 4 computers are able to see each other in the network. I recently bought a new HP dv6315 laptop with windows vista and i've also connected it to my network and am able to get online. However, I can't seem to be able to see my other computers on the same network and vice versa with the laptop. The other computers seem to be fine still but I'm wondering if there is a compatibility issue with the different OS.
