RDP function using the Viewer does not work for me at all. The Viewer is a Win10 Pro machine, and the Host is a Win7 Pro machine, both running latest beta, 22.214.171.124. RDP did not work either before the beta upgrade, on version 126.96.36.199, by the way.
I can connect just fine using Windows RDP app from the Viewer machine to the Host machine. I checked and made sure that RDP was allowed on the Host machine. When I click on RDP in the Viewer, nothing happens. I verified that the RDP port setting in the Viewer is correct, I tried with Direct Connection checked and unchecked.
Also, in the Properties, the Configure box is cut off - see screenshot link below.
I know you have to ask the basic questions, but as you can see in my original post I have already answered this question ahead of time, because I knew it would be the first thing you'd ask. I have already enabled Remote Desktop on the Target machine. AND I am able to connect via RDP manually using the Windows built-in RDP app. The problem is with the Viewer app. It does nothing when I initiate an RDP connection to a Host on my local LAN.
