Unable to access Remote Desktop after upgrade to Windows 11

Thus far I've upgraded 6 Windows 10 systems to Windows 11 and am doing a 7th upgrade as I write this. Two of these were Virtual Machines. One was out-of-the-box ready to upgrade and was running Windows 10 for about a year. The other 3 were Windows 10 with CPUs unsupported by Windows 11. I Acronis image-restored these three to new supported hardware with UEFI and TPM. All booted Windows 10 just fine and all upgraded to Windows 11 without problem ... EXCEPT, the last one I did. I used the same hardware as the other two, but for this last one everything works except I absolutely cannot remote desktop into it. I always get "Remote Desktop cant's connect to the remote computer ...".

I've checked the GPO. I've checked the Registry to confirm that fDenyTSConnections = 0 for both HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server and HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services. I've checked gpresult /H, and nothing looks odd. I don't know where else to look.

Futhermore, I cannot do regedit > File > Connect Network Registry from another computer on the domain. It finds the "object name", but I get, "Unable to connect to <hostname> ...". Also, I have this computer's C: drive shared, but cannot access it from other hosts.

It's been 3 days without remote access. It is very important to get this reestablished because this user does a lot of work from home.

What else can I look at?

    Hello,

    Have you verified if the Remote Desktop Service is currently running? To do this, navigate to Services and locate the Remote Desktop Service. Ensure that it's in a 'Running' state.

    As an additional step, open Command Prompt and execute the command netstat -ano to see if your system is still using the default RDP port 3389.

    I got it working. I un-joined the domain, changed the computer name and deleted the following registry settings:

    reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f

    reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f

    reg delete "HKCU\Software\Policies" /f

    reg delete "HKLM\Software\Microsoft\Policies" /f

    reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f

    reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f

    reg delete "HKLM\Software\Policies" /f reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f

    reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f

    Remote desktop then started working. Probably deleting the registry settings did it versus changing the name of the computer. I got this info from another posting on this forum titled: I have the "Some Settings Managed by your Organization" message when I haven't joined an orginization.
