"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is it that the user's sessions gets interrupted/disconnected from time to time and is it only one user?  If so, it sounds like a network issue (i.e. her connection is very reliable, etc.).  Does it only happen when that user is idle?

If it happens when they are idle, you might want to look and see if you ICA Keep Alives set in the Farm.  This helps keep sessions alive that can sometimes be killed by firewalls which kill connections after X seconds/minutes of inactivity.
