I've been trying to secure RDP to a new Windows 2008R2 server (using Windows Firewall) by only allowing RDP traffic from one IP address.
Under the "Computers" tab, it seems I can only allow user or computer authentications when the server is set to only allow secure connections.
So, I go to the "General" tab and under "Action" I set to "allow the connection if it is secure". That's when I get shut out, cannot reconnect over RDP and have to rebuild (this is a Rackspace cloud server so easily done).
Where am I going wrong? I haven't done anything to my local workstation (which I'm assuming I have to) as I can't find anything in the RDP client to change regarding encrypting the connection.
