Question : Terminal server logs off idle users

I am running Windows 2003 R2 Terminal Server with XP SP2 clients. After about 5-10 minutes of idle time I get logged off of the terminal server. It does not close the session. I have set my HKLM SYSTEM\CCS\Services\lannmanServer\Parameters Autodisconnect to fffffff to disable the disconnect. Is there a setting to control this?

Answer : Terminal server logs off idle users

I think the wrong term was used to discribe the issue. The screen must have been locked, displaying a login screen.
