This article will resolve an issue when WIN-911 will not reconnect to the SMS modem after the server is rebooted. The reason is that WIN-911 SMS Runtime is not releasing the port when the server is shutdown. The script is designed to stop the WIN-911 SMS Runtime during shutdown thus allowing it to reconnect at startup.
