Remote Desktop Web Access (RD Web Access) for External Internet Users

Today i went through an issue where remote desktop services configured for web access. We have a valid certificate and every thing seems to be fine.

We are able to access the RD Web APP both internally and externally, I can initiate RDP to the computers Internally and when it comes to External i am unable to initiate RDP, error " could not connect to the computer".

I have investigated on this and noticed that for External access of remote servers using RD web app we need to have any of the below condition.

  • VPN Access: If are having the customers VPN connected then we can access the computers using RD Web app. 
  • RD gateway server: The second option which is the very important option for easy RD web accessing of computer. We need to install the RD gate way service to the Remote Desktop Services role and need to configure this.

Few things to do after installing RD gateway: 

1. At "", log in as Administrator.
2. Launch "Internet Information Services (IIS) Manager".
3. Expand "test> Sites > Default Web Site > RDWeb > Pages".
4. In the detail pane, double-click "Application Settings".
5. Double-click "DefaultTSGateway".
6. Under "Value", type "".
7. Click "OK".

What happens if RD gate way role is installed and configured properly.

  1. The users who are coming to access the network resource  (Remote computers etc.) they will be authenticating to RD gateway and from there it will be routing to the selected computer and establishes a session.

    Issue is resolved we are able to access the network computers out side the internet using RD Web Access App successfully. :-)
