I am trying to establish a connection with rdweb, from a remote location, but after clicking on an application, I get the message: Cannot find external computer, contact the helpdesk about this failure.
Situation: my server 2008 r2 is a standalone server in a WORGROUP. Rd session host and licence server work properly. I installed Rd webapp and added some applications. Inside the lan I reach the website https://servername/rdweb, and i can open the applications. I did not install a certificate till now, so I get warnings about that, but after all the application works fine.
For external access i opened port 443 and 3389 on my router. Now I can reach the website from outside my LAN by https://publicipaddress/rdweb. I can login and see the page with the applications. Once I click on one of them I get a screen with a warning "This remoteApp program can be of harm for your local or external computer. Only make a connection if you know this program....". I think this is just the certificate issue. When I click on connect I see a little screen with "RemoteApp" in which i can see that it is trying to start the application. But after a few second I get the message that the connection with RemoteApp is broken, with the message wich I wrote in the title bar.
Could this really be a certificate issue? or any other ideas?
