This is an ethernet environment I am assuming?

Is there another machine on your network that might have the same IP?  You
could check ARP tables on other boxes before and after the problem.

Have you tried with a different switch?

Try running tcpdump on various portions of your network once the problem
happens.  Maybe the packets are getting out but not getting sent back
correctly.
