I am going to give you brief instructions. If you need more detail, let me know.In windows, on each PC run "cmd" which will bring up a command window.Type "ipconfig" and note the ip address associated with your network card. It will be in the form 192.168.0.100 or something like thatLet's suppose PC 1 is 192.168.0.100 and PC 2 is 192.168.0.101On PC 1, type "ping 192.168.0.101" ... it should get "reply from " and then PC 2's IP address.On PC 2, do the same thing, but ping PC 1's IP address. You should get a reply back.If this works, which it should, then we can go on from there. If not, then we have to get this to work before anything else.
