I'm running Exchange 2010 SP1 (Hosting mode, no EMC) and face some issues with the smtp and smtpauth.
Both services are answering on-and-off to telnet on their dedicated IP and ports, occasionally I don't get any answer from them and when I'm checking the services, I can see that Microsoft Exchange Transport service is not running.
When I'm starting it, everything works like a charm but few minutes later, it is stopped again.
When I checked the event viewer, all that I can see is that the service has entered the stop mode with no reason why.
how can I fix it?
