Not rsh related but things a few tools that can help diagnose a lot of
network related problems:
hostname and dig -x to check for dns related problems
tcpdump or the graphical ethereal to look at network traffic to see
what is actually going on.
tracerout and ping to check for remote machines and bottle necks/broken
connections.
nmap (remote checking) and netstat -tulpen (local) to see what ports
are actually open.

that last one, sorry).
If you have physical access to the remote machine (or someone you
know), you can start by trying to rsh from the machine to itself.
