Hello,
May I know if the error pop-up window in case of remote connection failure as shown below?
This error can be caused by many reasons, please try the following steps to troubleshoot:
1. Check the status of the RDP protocol on local and remote computer
To check and change the status of the RDP protocol on a local computer, see How to enable Remote Desktop.
To check and change the status of the RDP protocol on a remote computer, use a network registry connection:
- First, go to the Start menu, then select Run. In the text box that appears, enter regedt32.
- In the Registry Editor, select File, then select Connect Network Registry.
- In the Select Computer dialog box, enter the name of the remote computer, select Check Names, and then select OK.
- Navigate to and to .HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal ServerHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services
If the value of the fDenyTSConnections key is 0, then RDP is enabled.
If the value of the fDenyTSConnections key is 1, then RDP is disabled.
- To enable RDP, change the value of fDenyTSConnections from 1 to 0.
2. Check the status of the RDP services
On both the local (client) computer and the remote (target) computer, the following services should be running:
- Remote Desktop Services (TermService)
- Remote Desktop Services UserMode Port Redirector (UmRdpService)
You can use the Services MMC snap-in to manage the services locally or remotely. You can also use PowerShell to manage the services locally or remotely (if the remote computer is configured to accept remote PowerShell cmdlets).
On either computer, if one or both services are not running, start them.
For more information, refer to General Remote Desktop connection troubleshooting - Windows Server | Microsoft Learn
I hope this helps. If you have any further questions, please contact us.
Best regards
Jacen
