Have you got the Windows XP firewall enabled on either of the machines? If so, this may be blocking the pings from getting through?
at the command prompt, immediately after typing the ping command, type arp -a. e.g, my machine is 192.168.1.100, if I ping 192.168.1.5 which exists on my network, I get the following -
E:\>arp -a
Interface: 192.168.1.100 --- 0x6
Internet Address Physical Address Type
192.168.1.5 00-a0-24-cb-d4-84 dynamic
If I ping 192.168.1.6 which doesn't, I get this -
E:\>arp -a
Interface: 192.168.1.100 --- 0x6
Internet Address Physical Address Type
192.168.1.6 00-00-00-00-00-00 invalid
Note the Physical address is all 0's and type is invalid
If you get the former and the ping isn't working, the most likely cause is you have a firewall on the machine
