Привет !

Вот примерчик на Python'е сервиса под NT/2000.Сервис этот умеет загружаться и выгружаться, ну и регистьрироваться.

#
# A sample service to be 'compiled' into an exe-file with py2exe.
#
# See also
#    setup.py - the distutils' setup script
#    setup.cfg - the distutils' config file for this
#    README.txt - detailed usage notes
#
# A minimal service, doing nothing else than
#    - write 'start' and 'stop' entries into the NT event log
#    - when started, waits to be stopped again.

        # so that it also could be removed if the service is uninstalled.
        # Unfortunately it cannot be done in the 'if __name__ == "__main__"'
