Those with issues, can they ping (fqdn / ip) and resolve the server ok? Do they have a valid IP, Gateway and DNS address?
What happens when you actually try to connect, let's say with cord?
Can you telnet to the server on port 3389 ?
There should be no need to install a cert, it might prompt you to 'accept' or 'verify' the server and that should be it.

Microsoft Remote Desktop Not Connecting Mac To Windows 10
Can they connect ok when they are on the same network?
Use the new Microsoft Remote Desktop app to connect to a remote PC or virtual apps and desktops made available by your administrator. The app helps you be productive no matter where you are. Configure your PC for remote access first by download the Remote Desktop assistant to your PC and let it do the work for you. Using Microsoft Remote Desktop 10, the resolution of my 1920x1080 remote desktop is UNREADABLE, when remoting from my MacBook Pro 13-inch screen. Using Microsoft Remote Desktop 8, the resolution was perfectly clear. Therefore, version 10 is completely unusable for me. I will continue to use version 8. May 01, 2017 If that doesn't help, try using Remote Desktop in a new user profile. Follow the steps on the link below to create a new user account: Testing your user account to troubleshoot Office for Mac applications. Inside the Mac App Store, type 'Microsoft Remote Desktop' into the search bar at the top right hand portion of the window. The option you want is an orange icon with a computer monitor on it.
