Peer Network

I have 4 Machines on a Hub. 2 XP Pro, 1 win2K, 1 win98

all machines except the win98 have access to internet. all machines can see each other except the win2K machine. It can not see itself or anything else, but it can access the internet thruthe shared connection.

IP addresses are set, not dynamic.

How do I trouble shoot the win2K mach? I have tried to reset the IP (192.168.0.55) sub mask is set to 255.255.255.0, I have the shared connection mach at 168.192.0.1,
