I seems to have a problem getting my 2 computer to recognize each other. My first PC is running Windows XP My second .. running Windows 7 (64 bit) They are linked through a switch.. both PCs have 2 networking cards. Each PC has its own internet connection. (separate DSL modems..not that, I think, this maters) The only thing connected to the switch are the 2 PC's.. At first, I ran networking wizard. My Win XP would recognize itself and the Win 7 PC. The Win 7 PC would recognize itself and 'sometimes' the Win XP PC. Now.. both only recognize themselves. Sometimes, radomally, the Win XP PC will not even show itself on the network. So Im not sure what the problem is.. looks like it may be a multiple issue problem. First.. why is my Win XP PC seem to disappear from the network at random times?? And why cant I see each PC on the other. Before I installed Win 7...(while I was running Win XP 64).. the First PC did ths same with the sometimes disappearing act from the network. But I could always see the 2nd computer from the 1st. But not always the 1st comeputer from the 2nd. I hope that makes sense.
