Take a look at what does and doesn't work.  First off, can you ping the
host in a reasonable amount of time?  If not then a traceroute between
the two machines may lead to the problem.  Once had a server that sent
out a it's traffic for a certain host to the internet.  Bad routing
table was what it turned out to be.

If it were me I'd use tcpdump first to see what the differential on the
packet delivery
looked like.  tcpdump is unintrusive and that is why I would start
