Hello,
Thank you for posting in Q&A forum.
Can you kindly let me know what's the error message/screenshot you got?
Meanwhile you can try basic troubleshooting steps as below:
1.Check if RDP service is running properly in task manager -> services
Remote Desktop Services (TermService)
Remote Desktop Services UserMode Port Redirector (UmRdpService)
2.Run PowerShell command
Enter-PSSession -ComputerName <computer name>
qwinsta
and check if rdp-tcp is "listen" or not.
3.Check if you are able to ping the IP via tcp port 3389
4.Check Event Viewer -> Applications and Services Logs > Microsoft > Windows > TerminalServices and see if there's any insights.
Hope this answer can help you well.
Best regards,
Jill Zhou
