Mixed Terminal Services environment with 2003 and 2008 r2 servers. Have set session time limits on each user's account in AD. For example idle session time limit 30 minutes. This works great on 2003 servers. After 30 minutes idle it resets the connection, but on the 2008 servers it does not. I have checked each servers RDP-Tcp properties and override user settings is not checked. Have checked local group policy on 2008 r2 servers and no policies are set. Any ideas why the server is not using the User Account Settings?
