At first I thought they were just meeting the timeout threshold after some inactivity, but I experienced the issue myself while working from the admin console. I had only been signed in for maybe 5 or 6 minutes and all the sudden I was disconnected.
SmartMail Enterprise Version 12.3
I have already checked the IIS settings. They are set at:
Regular Time Interval:1740
Idle Timout: 20 minutes
There doesn't appear to be any information in the event viewer and the issue seemed to have started around 7/20/14. Can't really pin it to any specific event.
