Network problem - need help

[johnxsun]

Hello,

I have two PCs with XP SP2 installed. Both of them has wireless
connection to the same router that connects to a cable modem. The
router has IP address 192.168.1.1 and the PCs get IP address from the
router with DHCP, 192.168.1.101 and 192.168.1.111 respectively. Now,
one PC (192.168.1.101) can reach (ping) the other one, but the other
way is not working (192.168.1.111 cannot ping 192.168.1.101). I have
checked the two machines, the setup are identical. I have no idea why
the ping test only works one way. BTW, they both has no problem with
accessing network. Thanks for any help.

This is generally due to a firewall blocking the traffic...either disable it
or set an exception for ICMP or the other stuff you want.
