I'm getting a "Remote Desktop Connection" error: "Can't verify the identity of the RD Gateway ..."

I can't connect remotely to my server.

My server at work is on a private network, which we access using the Dynamic DNS services of dyndns.org.

(It is a SBS 2011 installation, although I don't think the O/S matters in this case.)

From home, I can connect to my work network OK (see attached .pdf) but then when I click on the link to connect to the server, I get an error message:  

'Remote Desktop  Connection - This computer can't verify the identity of the RD Gateway "focuspc.dyndns.org".  It's not safe to connect to servers that can't be identified.  Contact your network administrator for assistance.'

What is missing, please?  Thanks

I'd say it is an issue with your certificate. the focuspc.dyndns.org won't be an alternative name on the cert.
It might be easier publishing your web facing Terminal server out via your own firewall by using a NAT publishing to a static IP.

On your ISP domain management page, point the remote.domainname.com DNS name to that static IP, and change your SSL certificate to include the remote.domainname.com so you get a green light. I would recommend buying these certs.

I most say the issue could be just that you are using a self-signed certificate from you SBS Server.  You should try to get a certificate from a trusted company.

Once you get the certificate and is installed on your server, you should follow the step in the following link to install that certificate on clients computers requiring access.

Hope that helps!!!

By the way! I was able to get to your site by using https://focuspc.dyndns.org, no need to specify the port.
