Group policies are settings pushed into a computer’s registry to configure security settings and other operational behaviors. Group policies can be pushed down from Active Directory (actually, they’re pulled down by the client) or by configuring local group policy.
Some users have reported this error message saying Failed to connect to Windows service. You cannot connect to Group Policy Client Service. This problem prevents standard users from signing in. As an administrative user you can review the System Event Log about why the service is not responding.
Reasons Behind Error “Cannot Connect to Group Policy Client Service”:
This error arises when a computer crashes after rebooting process during Windows updates. The computer restarts after the crash and reports about an unexpected shutdown during Windows update. Right after this, it starts displaying this error. This could be caused by the loss of important Registry Settings required to initialize Group Policy Client.
Solution to Fix the Error “Cannot Connect to Group Policy Client Service”:
As mentioned earlier, this problem arises due to the loss of registry files. So, to get rid of this error, you should follow the instructions I am going to mention below.
1. Open the Registry Editor by pressing and Win + R on the keyboard and typing regedit inside the Run command box. Hit OK button after typing.
2. Inside Registry Editor, navigate to the following folder using the hierarchy structure listed below and check if a folder called gpsvc is listed there or not. This folder is responsible for service configuration and parameters. In a majority of cases, it would be out there.
Hierarchy structure: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
3. If everything is present, then navigate to the following folder using hierarchy path. It is the most important path and make sure that you don’t touch anything else.
Hierarchy structure: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SVCHOST
4. Inside SvcHost folder, there must be some keys and values which are required for the process to be completed. Check for a multi-string value GPSvsGroup inside SvcHost. If it is not present, then you would be required to create it yourself. In order to create it, right click on the SvcHost folder and select New > Multi-String Value. It would create a new value on the right.
At first, rename the new value to GPSvcGroup by right clicking over it and selecting Rename. Now, double click on the newly created value and change the Value data to GPSvc.
5. The next thing you might need to do is to create a new folder (key) inside SvcHost. For this purpose, right click over the SvsHost and select New > Key. Rename it with GPSvcGroup.
6. Now, click over the GPSvcGroup from the left and create 2 new DWORD For this purpose, right click on the empty space on the right and select New > DWORD (32-bit).
The first value should be re-named as AuthenticationCapabilities and its value should be 12320 in Decimal.
The second DWORD value should be called as CoInitializeSecurityParam and it must have a value data of 1.
7. After going through the whole process, finally reboot your computer and your issue will be resolved.
