We have external clients which we established IPSec Tunnels on our Checkpoint firewalls that have the rights to reach our RDS Farm. The farm consist of 8 Servers.
1 RDWeb Server
1 Connection Broker Server
6 RD Session host Servers
The external users are able to get to the RDWeb server and login then able to see the published remote apps. After they click on the Remote Apps they get another login which shows the Connection Broker then the error below comes up. Internal users of course are not having any issues.
Remote Desktop can't connect to the remote computer for one of these reasons:
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.
We have checked every setting possible and everything seems to be configure correctly, so to troubleshoot I gave one of the users an internal login and he was able to connect to the remote app using my internal credentials, so then I had him close the application which at the same time logs him off the servers. I had him try again using his credentials and it works, however if he tries again tomorrow then it goes back to the same behavior.
We are not running a gateway since we were told is not necessary since there is a VPN Tunnel, also we checked the logs on all servers and there is nothing. Windows Firewall is off on all Host servers.
please help this is driving us crazy.
Thanks
Carlos
