Some things to verify before troubleshooting further...

.rhosts for each user has the IP of the connecting box.
/etc/securetty has an entry for rsh (and also rlogin and rexec, if needed)
The rsh-server package is installed.
rsh is enabled under xinetd and xinetd is running.

You might also want to change your path so /usr/bin/rsh is called before
the kerberized version to avoid the kerberos errors.
