FIX: The Diagnostics Policy Service is not running

[symple_box color=”yellow” fade_in=”false” float=”center” text_align=”left” width=””] There is no need to add these services to any other localgroups since Administrators are the only group that can use the troubleshooting service.

To troubleshoot problems with the¬†Diagnostics Policy Service you’ll need to execute the following steps:

1. Open Start, Type CMD, Right-Click Command Prompt and choose Run as Administrator

Run as Administrator
Run as Administrator

2. Once Command Prompt has opened enter the following two commands, after each command hit enter.

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

Add Services
Add Services

3. Reboot your device and see if the troubleshooter is now able to fix problems on your system.

    Thank you again

  3. Yuri, you’re the man! I spend an hour talking to tier 1 & 2 tech support and they couldn’t figure out how to fix the issue. Then I just followed your instructions and less than 5 minutes later everything was working again. Thanks!!

  4. I am having the same problem as above. Had this problem a few months ago also and this fixed worked but it isn’t this time. Getting the same system 1378 error. Any help on this would be appreciated

  5. Hi thanks for this however while i was trying to follow your steps when i type in the required text in my cmd i get the following errors

    System error 1378 has occured.

    The specific account name is already a member of the group.

    Is there a fix for this?

    1. Hello Moe.

      First of all sorry for the delay in my reply. If you ignore the error and just continue with the next command, then reboot your device doesn’t that work to solve your problem?

      Please get back to me
      Yuri

    2. Hello Yuri
