I was having trouble creating an RDP client for Mac to a Windows Server. When I RDP to tha same Windows machine from another Windows machine everything worked as advertised.

When I opened a RDP connection from my Mac to the Windows Server I would ge the following error: 'Remote Desktop Connection cannot verify the identity of the computer that you want to connect to'

Since I was able to connect from a Windows Machine I was under the assumption that the RDP problem layed with my Mac. Wrong!

After trolling the internet for ages I finally found the fix.

Harassment is any behavior intended to disturb or upset a person or group of people. Threats include any threat of suicide, violence, or harm to another. Same issue here on MacOS 10.15.7 with RDP 10.6.1, which began as soon as I updated on Thursday. I have another machine running 10.6.0 and I'm able to connect just fine. This setting made it a computer I made a phone medium because I was bothering to put video on the pc.if you want to contact me send me mail: patman65412@gmai.

How to fix the Mac OSX RDP Error:

On the Windows Server you are trying to RDP to perform the following

• Ensure that RDP is enabled on the Windows Server and that the Firewall allows RDP.

• Open the Management Console (mmc.exe)

• Add the 'Local Computer Policy' snap-in
  Goto: -> Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Security

• Change the following two settings from their default (be aware that there might be a reason that MSFT has decided to set them to default. It might be advisable to revise those settings after a new Mac RDP client has been released)

• 'Require use of specific for remote desktop (RDP) connections' from 'Default' to 'Enabled', then select 'RDP' in the options pane

• 'Require user authentication for remote connections by using Network Level Authentications' to 'Disabled'
  Restart the 'Remote Desktop Service' or simply restart the computer

I was able to connect to various versions of Windows Server with this fix.

I'm not familiar with RDP Wrapper, so this may not help. However, when you setup your RDP session on the Mac, are you using your static IP address for your Gateway or for the Computer? I've had users with Macs try to place the RDP server address into the Gateway field and that won't work unless you are running an RDP Gateway.

I hadn't realized, until now, that Windows 10 Home doesn't allow for setting up RDP access. Is there a reason you may not use something like Google's Remote desktop, or Teamviewer, LogMeIn, etc? They would be safer than leaving port 3389 open for RDP on your home system.
