Hello,
We've set up RD services on a test server here, all of the roles bar virtualisation installed onto one server. I've setup an application to get the desktop in remote app services. The problem we have is that I get an RD Gateway error on running this application, even if it's run on a client in the internal network. Further complication is that for external users, they are pointing to a forwarding domain name which is not the same as the internal FQDN of the RD server, which I suspect is confusing the certificates which I'm creating from the server. Any help gratefully received!!!!
