Windows Admin Center – Remote Desktop only works from inside LAN

windowswindows-admin-center

I have successfully setup Windows Admin Center and everything works as epected from within the LAN. I forwarded the ports through my gateway and attempted remote access. Everything works as expected, I am able to view all tabs I try, but when I try remote desktop, it doesn't work. I tried connecting to both the server and VM consoles to no avail. It just shows a blank screen where the console should be (usually I get an Auth pop-up on the right hand side).

Any ideas on what to adjust or places I can share/look for debugging information?

Update: More Details

I have a Windows 10 LTSC 2019 client running Hyper-V w/ 2 Windows Server Core 2019 DC. One runs WAC (Gateway-Server) the other a DC. I'm currently adding computers to Domain to see if this helps resolve anything. There is another Ubuntu VM as well.

Settings:

  • Enabled RDP on machines
  • Disabled requirement for Network Level Auth
  • Proper SSL Certs installed on all machines

Things I have tried:

  • Powershell in WAC –> Works
  • Overview/Registry etc –> Works
  • VM Overview & Inventory –> Works
  • RDP to VM (Windows/Liunx) or Host OS –> Do not work, no "Auth Pop-up" on right hand side, just blank/hanging.
    • Confirmed working correctly from within LAN

Yeah, that obviously makes sense as Remote Desktop is bound to be limited by the limitations of - RDP.

Install an RDP gateway (a server program) and configure your local RDP settings to redirect nonlocal traffic to this gateway and it should work ;)
