The Diagnostics Policy Service is not running on Windows 10

If Networking is not working properly on your system running Windows 10/8/7, then this post will show you how to troubleshoot the problem. If you’re facing the issue of losing signal strength, the you need to first use the built-in Network Troubleshooter. You can find this troubleshooter in following manner:

1. Press Windows Key + Q, type troubleshooting and pick the same from search results.

2. Next click View all in the window so open which will take you to the All Categories option.

3. Next, look for the Network Adapter option here to open network troubleshooter and follow the on-screen instructions to perform troubleshooting, at last you may came around following result.


As you can see in the image above, the troubleshooting report says The Diagnostics Policy Service is not running, and the troubleshooter was unable to fix this, although it has detected it.

So in order to fix network issues due to this error, you can try the following steps:

The Diagnostics Policy Service is not running

1. Open an administrative Command Prompt.

2. Type following commands one by one and press Enter key after each command:

net localgroup Administrators /add networkservice
net localgroup Administrators /add localservice

The Diagnostics Policy Service Is Not Running

3. After executing both the commands, you’ll get The command completed successfully message. Close the Command Prompt window and reboot the machine, retry to connect the networks which are throwing trouble previously, this time you won’t face any issue.

Let us know if it worked for you.

    Thanks a lot for your help

  2. ^^ Glad we could help ๐Ÿ™‚

  3. Hasham Ali

    My problem, just happening today, is that my DPS works for about half an hour. Then it runs into some error. The registry shows the DPS as running, and I can’t change the parameters, even though I’m the admin. I’m trying this right now to see if it works. Will update soon.

  5. Ava

    Okay, this didn’t work. I tried these settings, rebooted, left my computer for 40 minutes, and came back to the internet connection not working. Same issues as before. Is there another solution I could try? I’ve even tried regedit, the internet options, etc. I’m going to try a system restore now, even though, on another forum, that was shown to not work.

  6. Ava

    The restore point seems to have worked for me so far. I’m not seeing any DPS problems now. I guess the fix is different for each situation.

  14. RandomGuy

    When I try the command options it tells me system error 5 occurred. Access is denied. I didn’t think that should happen since it is the administrative account.

  15. shaked

  16. Chance

    In the Command Prompt I get system error 1378. Followed by The specific account name is already a member of the group. Any idea why?

    This DPS problem is really annoying and I’ve been dealing with it for awhile so anything that can fix it would be great.

  37. Jackson

    Hello, if anyone could help me I would greatly appreciate it.

    I have windows 8.1. After my computer has been running for a half hour or so – varies wildly but is always a short window – the network connection fails. Upon troubleshooting, I get the Diagnostic Policy Service is Not Running error. Re-booting the machine is a temporary fix and I can use the internet for another half hour before it fails…

    I have tried the command prompt fix outlined above, but get the error:

    System error 1378 has occurred.
    The specified account name is already a member of this group.

    Can anyone offer some advice/solution?

    Thanks for your time,

  38. grim_r3ap3r

    Thank you, Thank you, Thank you!!! I have tried everything prior and was simply exhausted. Your steps above fixed the problem as you said. This all started after a Microsoft update.
