RDP stopped working after installing Windows 10 21H1

HI,

I have been using RDP on my Windows 10 Pro for workstations Pc for the last year.
Suddenly after installing the update 21H1, RDP stopped working.

After checking many forums, I have checked/tried below:

  • Firewall is turned off

  • Antivirus is turned off

  • Both server and client on the same LAN segment

  • both running Windows 10 21H1

  • Registry setting configured to listen on port 3389

  • Exported registry setting from working PC to non working PC

  • used administrator accounts

  • disabled "allow RDP to this PC" rebooted, enabled "allow RDP to this PC"

  • I checked the services are running, but I am unable to run (not disabled. I tried manual and automatic):
    - Remote Access Auto Connection Manager
    - Remote Desktop Services UserMode Port Redirector
    - Secure Socket Tunnelling Protocol Service

When I run netstat -a -n -o, I find that the PC is not listening on port 3389.

How can I get those services running and the PC listening for RDP connections?

Hello @FuWong-8975,

To check or change the RDP port, use the Registry Editor:

Go to the Start menu, select Run, then enter regedt32 and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\<listener>.

If PortNumber has a value other than 3389, change it to 3389

After you change the port number, restart the Remote Desktop Services service.

Also i recommend you to kindly go through the below link,
