Bumping this, as I'm having the same issue.
It seems that this thread was started years ago, and the "Solution" is just a tech saying he'll personally contact OP after a month of silence. This is not a resolution.
We have several people viewing this thread looking for answers, and many are finding none, despite this thread being marked as resolved.
The current resolution is outdated. There is no option within the program to "disable system service auto-restart" Even if there was, the session is not automatically starting as a system service. We know this because the "Restart as System Service" button is still clickable/viewable.
There is also no "Administration Center" in the program as Mikerr suggests.
Bottom Line: This is still a major problem that is affecting a lot of people. Please get someone to atleast respond to these forum posts so our technicians can get this issue fixed.
