This sounds like exactly the same problem we run into frequently here.
Our machines are administered by various individuals, and firewalls
are often accidentally closed or other problems happen, and until they
are fixed the cluster is barely usable.  Sometimes the admin is away
and I don't have the power to fix the problem or even to turn off the
machine!  It would be nice if Condor handled such situations gracefully.
