help with linux networking on dell optiplex 160L

I just got a optiplex 160L, installed mandrake 9.1 on it. mostly everything is
fine.
the network is configured and started well. but whenever I ping other machines
on the network like the gateway,
it will say Host Unreachable. I can ping my own ip though. This problem
persists with the
onboard network card and a PCI card I tried. Anyone knows what may be
happening? thanks! btw, the networking is working well under windows

Have you configured the interfaces?

What does /sbin/ifconfig say?
