So I have three computers in the house, and a Xbox 360. the 360 is easy, but I am having trouble getting the computers to do what I want. Both of the ones I have connected right now connect to the internet fine, but I want to be able to share file back and forth between them. Ideally I would like to see each machine from the other one as if it were a drive or something like when you open explorer, but so far I can only see the XP machines shared folder from my Vista 64 machine, but not vise versa. The set up is; cable-> modem-> Dynex wired router-> primary machine with Vista Premium 64-bit with all external drives connected to this machine... second machine with XP Home... third machine with XP Professional... I enabled sharing on one of my external drives, but still can't see it. Everything is plugged into my Vista machine, and I need access to all my external drives. How do I do this?
