Terminal Server Event Viewer Error 56

I have a terminal server set up with licenses for 20 users. Around the same time each day those users start getting kicked off their TC connections. This is one of the error logs:

The Terminal Server security layer detected an error in the protocol stream and has disconnected the client.

Have not been able to figure this out. It's running Server 2008 R2 Standard and is a very new Dell PowerEdge T610 box.

"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.
