Unable to connect to windows 2012 R2 server via RDP

Question

Hello,

Environment

Windows Server 2012 R2
Exchange 2016 CU22 with May 2022 Security Updates

After installation of Exchange 2016 CU22 and May 2022 Security update, we restarted the server and no issues were observed
After 2weeks , the server was not accessible from RDP , hence we rebooted the server from the ILO console.
The server is not accessible from RDP now
We are able to telnet to this server on port 3389
Checked and windows firewall is not having any restrictions.

Error message:

The computer cannot connect to the remote computer
Try connecting again.If the problem continues , contact the owner of the remote computeror your network administration

Checked group policies and found no group policy is causing this issue

Verified that registry keys are present and compared with another working server

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Any guidance is appreciated

Thank you

Answer 1

Might try from PowerShell from both source and target. (using target address in both cases)

Test-NetConnection -ComputerName "192.168.49.142" -CommonTCPPort "RDP" -InformationLevel "Detailed"
