Remote APP Via DirectAccess

Elhadi 256 Reputation points


I’m not able to start any RemoteApp from my new RDS 2019 farm when using DirectAccess from outside.
On the internal company network it just works without any problems.

I can access to the RDweb server, but when I try to start a Remote App it times out with the error message below.

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

Best regards

    By default, the RDP client verifies that the Remote Desktop service on the remote computer is listening on port 3389. If not, another application could be occupying the same port. To check whether any remote session (RDP-TCP) already exists on that computer.
    Firstly, we could check if firewall may cause the issue.
    After ensuring the firewall was not causing an issue, I consider you have a Remote Desktop Gateway deployed and you are accessing RDWeb from outside the corporate network. So, we went to the RD Gateway server. Please check the setting below:
    Also during logon did you type the username + password on the form of RDWEB. Try to type Domain\Username + password to log on remoteapp connections.
    If the issues still insists, start reading the Event Viewer messages available on RD Gateway. Looking into the event viewer, at the Applications and Services Logs > Microsoft > Windows >TerminalServices-Gateway node. It may record some information.
    Hope this helps and please help to accept as Answer if the response is useful.
