The troubleshooter stops here and does little to resolve the network issue. The Diagnostic Policy Service enables problem detection, troubleshooting and resolution for Windows components on your Windows operating system. If this service is not running, diagnostics will no longer function. This behavior usually occurs because of some misconfigurations of the system. We will go through all the solutions and try getting the diagnostics service back online so the computer can continue with the troubleshooting.
Checking Diagnostics Policy Service
Before we start updating drivers or executing commands in the command prompt, we will check if the service is running or not. If it isn’t, we can easily enable it and try troubleshooting your network again.
Solution 2: Granting administrator privileges to different modules
This error message might also occur if the modules ‘network service’ and ‘local service administrator’ don’t have administrative privileges. These modules require complete access to your computer so they can work with full autonomy and don’t hinder any blockades (problems with carrying out operations). We can try granting them these permissions and see if this fixes the problem for us.
Solution 3: Reinstalling the Network Adapters
If both the above solutions don’t work, reinstalling the network adapters might fix the problem instantly. We will uninstall the network adapter from your computer at first and then scan for hardware changes. The operating system will automatically detect the attached hardware and install the default drivers for it. If the default drivers don’t work, you can always update them.
After installing the default drivers, you can also update them to the latest version by right-clicking the hardware and selecting “Update driver”. You can either update automatically (first option) or manually (second option).
Solution 4: System Restore/Clean Installation
If the above method doesn’t work, it is worth a shot restoring back before any latest Windows 10 updates were installed on your computer or when you installed any application on your computer. If you don’t have the last restore point, you can install a clean version of Windows. You can use the utility “Belarc” to get all your licenses saved, backup your data using external storage and then perform a clean install. Note: This method is most viable in cases where the networking hardware fails to work after an update or after installing an application. You can check the method on How to perform a system from our article in the second solution.
