"This computer can't verify the identity of the RD gateway"

exampasser

MS strikes again. Today I'm trying to help a relative access her work computer via RDP after their DC was upgraded to either 2008 or 2011 Small Business Server. Upon Trying to RDP, I get the message "This computer can't verify the identity of the RD Gateway <hostname>. It's not safe to connect to server that can't be identified. Contact your network administrator for assistance." There is no option to ignore the warning and proceed, completely ridiculous. The DC is using a self-signed certificate and I've followed several guides that all said to install the cert under the Trusted Root Certification Authority category but no luck.

Edit:Came back to it, found anther guide and now got it working.
