Windows could not connect to the Group Policy Client service
This issue may appear in Remote Desktop Services environment where users can connect to Remote Desktop Server to work in their applications.
If user was trying to connect to his Remote Desktop and got the following:
Solution for this would be to go to your server where you have Remote Desktop Services Manager running and search for specific processes. What you want to do is to click on “Processes” tab, sort processes by ID and look for group of processes which have only 4 of them under same ID. Once you find such group, right click on “winlogon” and logg it off.
Here is example on the screenshot:
In this example, you see only four processes running under ID 52. It’s quite likely orphaned processes as normal one should have more than four running in same time.
If you identified all such orphaned processes and logged them off, you user should have no problem to log into his Remote Desktop after that.
