Does each system have a unique IP address? Do you have a DHCP server? If not, you need to assign each system a valid, unique IP address on the same subnet before you can do anything.
make sure the IP for both computers start with the same two numbers i.e. 192.168.xxx.xxx

Those are legitimate IP addresses, so you're fine there, but you're saying that you can't even ping the other? Do you have the XP firewall installed? Can you ping from one to the other but not vice versa? Until we can confirm that basic TCP/IP connectivity can be established, there's nothing else to look at.

in the help and support it will tell you how to do.it is
easy in 98 and me but in xp you must use the xp disk.
