I never tried exactly what you want, it looks like Windows doesn't cooperat=
e so
its good to know not to waste time trying that.

One way I have a server set up is by installing a script (that watches the =
real
server) as the service, the interesing part of the script is this:

# Keep checking that it is working every TIME secs
trap '$DAEMON stop; exit' SIGTERM SIGQUIT SIGKILL
while true; do
  sleep $TIME
  $CLAMDWATCH -q -s $SOCKET &&
  ( $DAEMON stop
    sleep 1
    rm -f $SOCKET
    $DAEMON start
  )
done

I know this is not what you asked, here I have a program that tests to see =
if
the daemon is not responding and the script restarts the daemon in that cas=
e.

Back to your test, I think you are using the wrong exit codes.  Windows doe=
s not
use the Unix like codes 0, 1, etc.   I don't remember Windows codes but they
where something like (exit_code << 8 | windows_flags) that means 256 instea=
d of 1.
