I have installed an RD Connection Broker, web access, and licensing server (12rdgate1). I have linked this server to a public ip address and natted the standalone firewall to access ports 443, and 3389.
When I browse to the website, I am presented with a login. After authenticating, I get presented with a published RemoteApp. After clicking on the RemoteApp, I am presented with another login screen. After logging in, it appears that it is doing something. After a few moments, I get an error message: "Your computer can't connect to the remote computer because an error occurred on the remote computer that you want to connect to. Contact your network administrator for assistance."
I have checked the event viewer on 12rdgate1 for errors in the system, security, and application logs and can't find any entries relating to the time of the event. I've even cleared the logs (after saving them), and re-tested with no entries relating to the problem being shown.
I only have one terminal server in the collection for the remote app. I have also cleared those logs (system, security, and application), and re-tested, with no entries relating to the problem being shown.
If I attempt to do this internally, I don't get errors, and things work the way that they should (Using a laptop that is connected via wireless internally, and through a hotspot to get access externally). I have even tested this from home with the same results.
I have seen in articles relating to Windows 2008 R2 about changing the security negotiation to a different level, but, can't find that to test here.
Certificates are from a separate certificate server that was created internally, and the certificate root has been imported into all machines, along with the intermediate certificate as well.
I've run out of things to check. Can someone point me in a direction to find this problem and fix it?
Thanks for your time.
