There should be *one* log file, /var/log/actest3.log.  Which ones are you
looking at?  Try explicitly specifying it using the "-1" and "-2"
cygrunsrv options.  Also, what does the Windows Event log show
(on Win2k, right-click on "My Computer", choose "Manage", then "Event
Viewer"->Application).

$ net helpmsg 67
The network name cannot be found.
$ net helpmsg 5
Access is denied.

I'd suspect something wrong with your mounts (e.g., they aren't system
mounts), or directory permissions.  The output of "cygcheck -svr" from a
regular shell would have been very helpful (and it *is* requested in the
Cygwin problem reporting guidelines at <http://cygwin.com/problems.html>,
which you should read in any case).

Which probably means that the service runs with an empty environment...
Unless...  Try specifying /bin/env explicitly, just in case, as well as
the full path to the tempfile.  Putting 'echo "$PATH" >&2' into the bash
script might also be helpful.

Did you try trapping SIGINT in the bash script and printing out a message
before exiting?

Googling for "system-owned window cygwin" should give you a couple of
recipes.
