I have 2 win7 PC's and need to network them for file sharing. I did have them networked through my router with everything working great. I am now without broadband and attempted to network them using a gigabit switch, both of them now see a public network but not each other directly. Question is how do I get them to recognize each other in this configuration or would it be easier to use a crossover cable directly from each pc's lan port? Thanks.
