I'm not a network expert, but I do play one in the office.

Are you using names or numbers in the ping test? If using names, try numbers. If that works, there must be something wrong with the name resolution (/etc/hosts, dns,...)

Did you try traceroute ?

Check out routed / gated

Check out /etc/gateways and /etc/networks on the failing node.

Check out the net masks: ifconfig -a

Restart the network?: rcinet restart

hth,
Hein.

try ping -r to be sure correct interface will be used. post output of ifconfig -a and traceroute from both machines to each other.
