Sometimes you receive an error message – The connection to a Windows service could not be established. This usually occurs when the operating system is unable to boot or connect to a system service required to execute its commands. This can be the Group Policy Client Service, System Event Notification Service or anyone else. If you receive this error, the troubleshooting depends largely on the service in question. This post can guide you on the direction to take.

Before proceeding, first create a system restore point.
1] First note the name of the service that did not respond. Run now services.msc and search the name in the Services Manager. Here, we take the example of Group Policy Client Service as shown in the photo.
When you find the service, double-click it and identify the service file name. Here it is gpsvc.dll
The service is responsible for applying settings configured by administrators for the computer and users via the Group Policy component. If the service is disabled, settings are not applied and applications and components cannot be managed through group policy. Any components or applications that depend on the Group Policy component may not work if the service is disabled.
Next search for gpsvc in Windows folder. Right-click and check its properties. This is for your information and confirmation only.
In open service property windows, make sure the service is not disabled. Also make sure it is started. Click the Start button to start the service.
Then open the Dependencies tab. Here you can see the services and system components needed for gpsvc to work properly. So also check these services and make sure they are in good working order.
In this way, you must first identify the problematic service, its file name, and then ensure that the service is not disabled, but that it works with the services on which it depends.
