I have two Windows Server 2008 R2 Datacenter Edition with Terminal Services Role installed. Both are using the same GPO. On only one of the servers, when I open tsadmin.msc and try to remote control a user’s session the users session is immediately disconnected. I have tested using Windows 7 and XP with the same result. The Windows 7 client Network level authentication is supported and on the XP machine it isn't. I see in the event view the application popup where I am requesting control. The only other log entry that I can see would be in the security log. Any ideas?
