We have a Windows Server 2008 R2 machine that needs to have a user logged in constantly. We login to this machine using Remote Desktop Connection and then just disconnect the session without logging out.
The problem is that after 24 hours, the user is automatically logged out.
I've tried fixing it by opening the Remote Desktop Session Host Configuration, opening the properties for the RDP-Tcp connection, going to the Session tab, and checking override user settings. The problem is that the field End a disconnected session is greyed out. I can't change the value of it.
How come I can't change it?
