That most likely means that this application needs network access.  If
you log in via public key and don't have a password stored in registry
via 'passwd -R' and cygserver running to use it, then you won't have any
access rights to non-local resources.

If all you need is indeed to run one script, you might alternatively be
able to set up a service that starts under a network user and just runs
that script when triggered by your remote user login in via ssh.

Achim.
