There are inumerable commercial solutions to the problem of deploying
executables (or anything else for that matter) to windows machines.
The issue you have is that this should happen only if the daemon is
not in use (terminating a schedd that is running jobs is prob not a
Therefore unless you are willing to take this (uncommon admittedly)
hit you need a mechnism for determining when this is appropriate on a
machine by machine basis...
One means of ensuring that the machine eventually becomes free for
upgrade is to reconfig the START expression. for schedd's I can't
think of a simple (start no more shadows" but don't kill running ones"
expression of the top of my head but steadily reducing the max jobs
running to the number of active shadows would do the trick (if
The alternate is just sit and wait till condor_q -run says nothing is
running...not guaranteed to ever be true though.
Most of my windows admin friends swear by active directory (if you can
afford it and the time to learn it) for pushing out machine setups but
this may well be overkill/overpriced for you
