Since moving on to Vista I have had issues with the network. All computers (4 total 3 with vista 1 is xp) have no issues with internet access through the router. I can see some computers on one computer while not on another.I have sharing turned on and two of the machines are mine and in the same room. I can see the one but cannot access it from the other. I have turned off firewalls, antivirus, and went through the network settings to make identical. Any ideas?
