We are experiencing the same issues as described in this post on TechNet. We use Remote Desktop to log into Windows XP machines remotely. If the connection is lost the user is logged out instead of being disconnected. I checked in GPO for the remote desktop settings but they are all set to no session limit. It doesn't matter for how long the connect is lost, the log off happens immediately.
This happens when using both Windows 7 and Windows XP. Are there any other policies I should check? I see this question asked a lot online but I don't see a solution.
Our servers are Windows Server 2003, clients are Windows XP.
Update: I tested using remote desktop into a Windows 7 computer and the user remains logged in. So this is isolated to Windows XP it seems.
