don't know anything about networking. I'm learning as I go. I have 2 computers networked together by cross over cable using ethernet. One computer is Win xp other computer is Vista. Win xp is the host. Win xp has dsl and printer hooked up to it. They both are in the same workgroup. I ran the Network wizard on both computers. Vista in network says...connected to network...local only. Win xp in network connection say local area connection...connected and firewalled...and it says the name of the network card. I tried to ping Vista it says reply from 18.104.22.168: Destination net unreachable It also says that 4 packets were sent and 4 received. I tried to ping Win xp it says request timed out. It says 4 packets sent..4 lost. I have ZoneAlarm protecting my computer. I don't know if that could be contributing to the problem. Perventing Vista from getting to Win xp. I haven't setup sharing yet. Can anyone help me please?
