This is almost an FAQ for services and has nothing to do with Python. When running from a DOS box, the service is running as your user, so has all your drive mappings etc. When running as a service it generally runs as a different user, so does not. Worse, the LocalSystem account generally has no network access. The solution is generally just to use the complete UNC name '\\server\share' in your Python program - this generally works fine (but still will generally *not* work for the LocalSystem account - so you will also need to change the username) Cheers, Mark _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
