network problem

[Jamon Camisso]

So I've run into a really strange network problem. Box X had IP Y. IP Y 
was moved to box Z. Box X and Z are behind the same switch, and use the 
same gateway. The switch is a 3Com 4400.

The IP is accessible by any host behind the switch. But it only routes 
properly when on box X. Box Z, no luck. I've tested iptables on box Z, 
and disabled it just to be sure, no luck. Box Z also works with all the 
other IPs it has assigned to it, that are on the same subnet as IP Y.

I'm thinking it is an arp cache on the switch or router, but don't have 
access to either to check. You can see where I'm going, how can I get 
box Z to be accessible? Arp?
