I have 3 computers on my network. I have just spent the weekend reformatting all 3, so they all have a fresh install of windows on them. I have installed ESET SS4 on 2 of the machines, and my current problem is this: Computers A & B have SS4 installed, Computer C does not. In the networking section of windows, Computers A & C can see themselves and Computer C, but not each other (A cannot see B and Vice Versa) I have the firewall in interactive, and have set the ip range that they all use in a trusted zone, but still nothing. Also if i try and PING from A to B, or B to A, i get "Request Timed Out" I feel i am missing something tiny, but if anyone could help I'd be very grateful. Thanks.
