I'd like to activate drain mode on our terminal servers: http://blogs.msdn.com/b/rds/archive/2007/06/15/introducing-terminal-services-server-drain-mode.aspx
But my policy won't let me to, if I do chglogon /drain it says "connections are currently ENABLED by group policy ... unable to change".
I can set the policy to not configured but I am not eager to, I don't want to impact users.
located in Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Connections -> "Allow users to connect remotely using Remote Desktop Services" –
Have you configured it too and it works correctly?
