Internet was working fine on my laptop and other portable devices. But when I turned on my PC the next day it was showing no internet access or limited connectivity on the wireless icon in the Windows status bar. I was facing diagnostics policy service is not running error when I tried to diagnose the network problem. If you are facing the same problem on your Windows 10, 8 or 7 computer, then follow the steps below to fix this error.
If you have fixed this problem once and occurs again then you must read this comment below or repair the system files that might help you to solve the problem again.
Fix Diagnostics Policy Service Error
Before trying diagnostics utility, I rebooted the network devices like modem and router. But the internet wasn’t working on my PC. Then I used the same internet connection on another machine, and it was working fine. I thought something is wrong with my Windows network settings and I performed the following steps to solve the problem. You should follow these steps to fix the problem.
- Try to troubleshoot the problem using Windows built-in Network Diagnostics tool. Right-click on the limited connection network/WiFi icon in the status bar and select “Troubleshoot Problems” from the menu.
- Diagnostics tool will take some time to analyze Windows network settings and will show you the problem if found any and ask to fix that.
- If you are getting an error message like “The Diagnostics Policy Service Is Not Running.” The error shows that the diagnostics service is not running and we need to run the diagnostics policy service and fix the problem.
- Press shortcut Windows+Q keys or Press the Windows key from keyboard and then type cmd, this will search the Command Prompt. Right-click on Command Prompt search result and select “Run as Administrator” option from the menu.
- In the Command Prompt Window, you need to run the following two commands one by one
net localgroup Administrators /add networkservice
net localgroup Administrators /add localservice
If the command executed successfully, then you will see the success message as shown below.
NOTE: If you are getting any error while running these commands. Make sure you run the command prompt as administrator. Also, try to modify the command, just replace /add with /delete and run both commands. After that rerun both commands with /add same as mentioned above or showing in the screenshot below.
- Type Exit and hit Enter to close the command prompt. Now, restart your computer to apply the changes.
- Now, troubleshoot problem again see step-1 above.

I hope your problem will be solved now, and you can enjoy internet on your computer.
Fix the root cause of “Diagnostics Policy Service Is Not Running”
One of our expert readers shared his opinion. The above method may allow accessing the internet, but this doesn’t fix the root cause which is the system’s files corruption. To fix internet problem properly you need to repair the system files and restore it. To do that you need to follow these steps.
Restore your Windows to an early restore point to undo system changes that may cause system files corruption.
- Press Windows key from keyboard and type “system protect” to search it. In the search results click “Create restore point” option.
- In the System Protection window, make sure Windows partition is selected under the “Protection Settings” section. Like in my case C: System drive.
- Now, click the “System Restore” button and follow the on-screen instruction to revert back your Windows to the latest restore point. At this step, you can check if your internet is working without any error. If the problem persists then continue reading.
- Once, restore completed open up the Command Prompt as Administrator. Simply press Windows key and type “cmd” and then in the search results right-click on the Command Prompt and select “Run as Administrator” option.
- In the command prompt windows type the command
sfc /scannow
this command starts scanning your files to find any corrupt system files. If this command failed to fix corrupt files automatically then it will give some suggestions. As you can see below in screenshot this found some corrupt files but unable to fix the problem automatically.
- In that case, you should run the following commands. I would suggest, before running the following command you should read about DISM here on Microsoft website.
DISM.exe /Online /Cleanup-Image /RestoreHealth - After running this command reboot your computer and scan once again with the command
sfc /scannowand it should return without any corrupt files found.
Check Diagnostic Policy Service Status
You can also check the diagnostic policy service status form the Windows Services utility.
- Press Windows+R keys to open the Run window, type command
"services.msc” and hit OK. - In the Services window scroll down to find a service with the name “Diagnostic Policy Service.” Right-click on this and select Properties, here make sure this service is up and running as shown below.

I m also facing the same problem ,plz help..☺
It works now since using run as administrator. Thx
It works fine now, thank you so much!
I tried all steps got the same messages but it is not working. I have windows 8
Same thing for me, I do everything get the same message yet does not work
I did this solution a week ago but the problem has reoccurred and now this solution will no longer work. The first command completes successfully but after inputting the second command I get the error, *The specified local group does no exist.*
When I try to repeat the solution again the first command then fails with the error, *System error 1378 has occurred. The specified account name is already a member of that group.*
no work for me please help, both ways are useless on my laptop 🙁
Thanks, I apreciate your imagenes instructions. It works
Im still having the same problem on my laptop running on windows 7, I can’t start my diagnostic polycy . please help me.
Woo-hoo! The first option worked for me! Thanks so much!
Thank you so much worked perfect. Make sure you are on as the admin and restart your computer. I have windows 10
Thankyou sooooo much it didn’t just solve my IE11 issues but problems i had with Microsoft edge so thank you once again_!!!
I have tried several times but it’s still not working d’t know what else to do can someone help me ??
I had the issue today on my wife’s pc. I was able to do the command prompt through the ‘all apps/windows system’ then right click, more, run as administrator. After that, I did the steps listed for the command prompt above. 1 restart later, the pc has internet again. Thanks so much for this.
I have also tried every step in here with no luck. I ran come as admin and got the response “account name already a member ” and when I tried to use services.msc I got therefore 5:access denied”. Anyone have any more help?
Thus is the 2nd time this has happened. The first fix I made using info I got here worked great. I tried doing the same thing today but I got the message “System error 1378 has occurred”. “The specified account name is already a member of the group”. I’m getting very frustrated with Microsoft and why is this happening?
I’m having the same problem as Ben. I can’t get past the error 5: access denied. And I ran the commands as admin. Does anyone have any ideas about this problem? Everything worked fine yesterday and I haven’t changed or installed anything. I’m guessing this is due to a Windows update.
I followed instructions, restarted and Internet access was restored. Yay! BUT, when I opened Services, the Diagnostic Services Policy showed AUTOMATIC, but was not running. I tried to start it, but got a message saying it started then stopped. So, I’m wondering if something else is wrong.
Thank you so much for your very clear instructions; they worked. Other places I looked were giving the same instructions, but not nearly as clearly. I am now a hero to my friend whose frustration level had reached hysteria.
This worked great! Thank you!
No success yet. Any other solution please?
When I hit the start button in the diagnostic policy service properties I receive the following message
Windows could not start Diagnostic Policy Services on local computer
Error 5: Access is denied
Thank you, thank you, thank you! This worked for me!
Done all steps it shows diagnostics police stopped. When i hit start i get error 5 cannot run on local computer
Can you help me please
Same error 5. Any answer on this one yet
when u done type the name of dmc,click run as administrator
At first it said access denied but when I run as administrator it worked tnx 🙂
Wow! Thank you! It really worked! God bless you, thanks for sharing your knowledge.
Great solution
Appreciated,,,,,
anyone here with Microsoft?
This worked once I typed exactly! Didn’t leave the space between Administrator /
Now I just have to figure out how to get my firewall working again, but that will be another day. Working from an old XP was rough!
Thanks a lot…..problem got solved.
After i execute the first command it tells me “The specified local group does not exist.” So any help on what i should do under these circumstances??
Tried everything listed above as an administrator and still getting the error 5 everyone else is getting…
Anyone have any other idea?
This all started for me after an update from Windows… is that the case for all of you as well? Starting to think they did this on purpose… :/ :# :{
I dont know if you’re still experiencing the problem or not but mine did the same after a windows update. 🙁
The fix worked perfectly. Thanks
It didn’t work on my pc. I will try it again.
Thanks so much! Fixed my problem. Fingers-crossed it does not happen again!
After running all the command the service cant start still giving error 5, what else can be done
See the reply to 2nd comment above it seems rights issue with you as well.
thanks… big helps for me…
Amazing its working
I have the problem on a freshly installed Windows 7 (SP1) machine.. even reinstalled the OS.
Machine was installed in a workgroup with (domain) DNS servers supplied via DHCP.
This must be somewhat of a security “feature” Microsoft has build.. i’m digging further to find te real cause.. Unless someone else can clarify the cause of the problem..
This solution worked well for me.. just wondering why this happened? I was working on my computer and i left it idle for some time. When i came back.. pc was in power saving mode. I tried moving the mouse etc but it was just showing blank/ no display on monitor. I did hard reset after that i started facing this problem.. Anyways all fine now. Thankyou!
It’s work in my pc… .. Thank you so much
Your steps worked like a charm! Thank you so much for these steps.
Thanks so much 🙂
It worked. Thank you so much. 🙂

To implement method one, make sure your firewall is turned on. Sometimes through your antivirus software like McAfee. First i tried it didn’t worked but after turning on the firewall via McAfee it worked.
After executing these steps also I am getting error as below
Windows could not start the diagnostic policy service on local computer.
error 5: access is denied
Ty bro
Thank you so much.It is working . Did a great help

I followed the steps with the commands above and resolved the internet connection problem. Saved $120 that Dell would have charged me. Thanks!
Happy to hear that you saved something with the help of our guides.

Are you using Windows Home version?
I tried everything to fix my limited access problem. I found this fix and it WORKED!!!!! Thank you so much.
This worked for me! However, the icon at the bottom of my screen in the tool/task bar shows a computer monitor with a red “x” going through it. Hopefully that’ll be gone next time I fire up my laptop. But, thank you so much!!
Thank you. It worked perfectly. 2017 – dell computer
I followed the steps and it worked for a short period of time before the error returned. I keep using tgebsteps to reset, but is there a permanent fix.?
Thank you so much. I had the error 5 issue but it is fixed thanks
I have too facing this problem.. and followed above CMD steps.. works me fine.. thanks you for sharing useful tricks..
Hey thanks for this little tip. I was overclocking my cpu and I must have seriously made a mistake. I changed a few bios settings, ran intel burn test and my computer wigged the f out. After I got it stable and wiped out the overclock I had no internet and got that same error when running diagnostics.
My only mistake was not paying enough attention to your instructions to realize there are two separate commands there. I put in one thinking the other was a duplicate as they look very similar. lol
Thanks again. I’m back up and running!
As others are saying, make sure you are running an elevated command prompt (right click, “run as administrator”). I am running 7 pro so I just usually start typing “cmd” in the search bar on the start menu and right click when the suggestion appears. Also, you do need to restart, or in my case, restart twice, haha!
I had this issue a month ago,
I fixed it using the above advice
Now I have the issue again, and I have the Error 5 issue.
Yes I’m running as Admin
I’m getting “The specified local group already exists”
I tried rebooting, removing it and the adding it again… no luck
I’ve gone into regedit and given it permission to edit from all users
I’ve gone to Run> services.msc then found it and tried to start… Access denied…. even after giving permission to all users.
I’m out of ideas
My only possible idea is the diagnostics policy service its self is corrupt and cannot run.
If this is the case, how can I replace it with a functional copy.
Is it an integral part of the system? Do I need a fresh copy of windows?
Is it faulty hardware that could cause this? or is it a corrupt system?
I’ve followed multiple identical cmd instructions in Administrator mode and STILL keep getting the error 5 message. I’ve read all these and other blog replies and corrected earlier errors. Still the same error 5. I only have one user account with administrator privileges.
Thank you so much ?
Thank you so much!!! The cmd as admin commands worked for me <3
thanks it worked
I have a Lenovo TAB2-A with Windows10. Never before have I had so many problems with a computer and Windows10 updates. It only has 32Gbt Drive, which couldn’t handle the latest W10 major upgrade. I had to install a 32Gbt microSD to tx all data files and some applications before W10 would complete the update. The Reason for leaving this message is that I just had another update which stopped my wifi working or allowing access to the internet, even slowed the device to a crawl and I had difficulty getting at the Settings and Control Panel. I followed your instructions about this “The Diagnostics Policy Service Is Not Running” problem and it worked. Well done and thanks for the techno info.
Thank you soo much, worked like a dream
Thanks trickyways ? working fine
No use if happen every times, window diagnostic policy service state running in services but it still running error many times. This solution cannot one times solves clear forever. it will still not running after someday and sometimes cause 0-xc000021a error. mostly after 0-xc000021a error network return normal for a time.
It works in my laptop
Thanks a lot 🙂
This is helpful

Same thing here, error 5 message. Thanks anyway for a crystal clear instruction path. Just a shame it didn’t work for me.
I did the second step and i hit start for diagnostic policy it says: windows could not start the diagnostic services on local computer
Plz help
Hi guys. I followed the (very clear – many thanks) instructions above and it all entered OK but didn’t fix the problem. However, I found this on another forum from someone going by the name Spunk.Funk. and it works!
Go to Start/Search and type in devmgmt.msc
Right click the devmgmt.msc icon and click on Run As Administrator. The Device Manager box opens.
Click on Network Adaptors to open it. Right click on each one in the list and uninstall it as the option appears.
Once this is done, right click on any device (I picked Monitors) and click on the option Scan For Hardware Changes.
This should start a new hardware wizard and re-install the appropriate adaptors. After a few flickers of the screen – Presto. Internet back on , yippee. Many thanks to Spunk.Funk (the thread was closed). Hope this works for you.
thanks. It works
For all the people saying they are getting the code:5 error just ignore it and type the same code in the above fix photo above again below the error message (hit enter will give u new start line.) Type in the code this guy states again n photo above EXACTLY AS IT IS WRITTEN AND WITH SPACES. THEN REGARDLESS IF ERROR MESSAGE TYPE AGAIN. I HAD THE SAME ERROR MESSAGE THE 1ST TIME I TRIED TWO in put it. I just skipped it and typed in the command line again above all comments, twice. Then I closed it out as it staTed it was good. Then I did a restart and it started fine. You may have two put in the two command lines a few times.
It worked like a charm, thanks man.
dis post was really helpful thanks…. but instead of opening services after running the command i think its better to just reboot the system first.
it’s work!
THX
Waaaooooo.. It just worked like Slice on cake for my Laptop.. Gr8.. Many Many Thanks
Am also experiencing error-5 Acces denied what do I do ?
I was able to overcome the “error 5 – access denied” situation by simply uninstalling the offending network card (under Device Manager) and then reinstalling (in Device Manager).
Man genius you are..thanks a lot
thanks this worked like a charm
thanx , this worked like a charm
I also get the error 5 message, I have tried all advices, and the two groups are already added with the cmd window. Please, how do I fix the error 5 message? 🙁
Thanx bro.. it worked✌️✌️
Wow! works Great! Thanks man!
All of this just reminds me why I love my iPad so much. IT JUST WORKS!!!
I know this is an old thread, but this advice is just plain bad. If you’ve added localservice and/or networkservice into your Administrators group, I would highly recommend you remove them as soon as possible. These accounts were created to allow services to get the access they need without needing administrative rights. They were never designed to be added to the Administrators group and never should be! This fix basically gives unfettered access to anything running as a service or that uses the Network Service account.
I’m still looking for a real fix for this, but the one from hhgeise is not it. It may appear to fix it now, but you’ve basically locked the back door after knocking out the front wall.
Thank you , followed the steps and computer back running fine .
I appreciate the help , cheers .
Thank you tricky ways! Your solution corrected my problem. Very nice of you to post! 🙂
Those two DOS commands did the trick! Thanks for this.
i tried this exactly how it told me to do it, but it made my laptop really slow. How do i fix this?
This CMD command worked like a charm so far and are now running again in the services which they were not able to come back on. Now just need to restart the PC, hope this solved the problem.
So far thanx
Thank you! worked for me.
thank u bro 4 ur kind suggestion….it worked for me…
I have tried to enter both command, and its working but diagnostic policy service still not working. It show error. Network show unidentified. Please help to advice. Thanks
Is anyone else also sick and tired of all the time that gets lost dealing with pc problems, constant update interruptions, computer slowing down?????? I’m done with Microsoft. I’m telling get an Apple, it just works. I especially recommend the iPad Pro: quickly turn on (No boot up time) cellular connectivity, the awesome onscreen keyboard, endless apps to do ANYTHING and best of all IT JUST WORKS!!!!!!!!
Thank you guys !
Wonderful. Thanks very much
Problem fixed! Thanks a lot!
The command prompt worked perfectly. Thanks!
Btw, what causes this issue in the first place?
Windows update
Thank you very much!
Awesome☺
Yes! 3 years! And it ended with this process. Thank you very much!
I was having problems with my diagnostic service, followed your instructions and it’s now working ( thank you ) but my wireless is still not working, I’ve tried everything I can think of , all the troubleshooter days is Ethernet cable unplugged, it won’t even recognize my router.
I experienced the “Diagnostics Policy Services not running “ on my work laptop. This was a major problem as it had all my work information on it. I panicked and had my IT person at work try to fix it, that didn’t work. I next contacted Dell Tech Support, that didn’t work either. They suggested I take it to a local computer service company. I finally googled it and found this website. I tried the “cmd” command and entered the information on this website, and it worked! Thank you for saving my laptop. Even Dell couldn’t fix their own laptop! I can’t tell you how much I appreciate it!
Respectfully,
Larry S Reno, NV.
It doesn’t work??? it is written that system error 5 has occurred what should I do know plzz replay I am in stress
Plźzz help ?????????????
Thanks man, you just really saved my day. Keep up!

Can’t thank you enough for this fix – very well explained and worked like a charm on Win7
Thank you bro, you save me
Thanks, it worked.
Hello THANK u it was worked mates!
Thanks that worked
I have done both steps. The first step worked after I restarted my laptop and stayed connected for a little bit and disconnected again. I tried troubleshooting like instructed but said Diagnostic Policy Service not running again. So I did the second step and right clicked on DPS and it says “Windows could not start the DPS service on Local Computer. Error 1079: The account specified for this service is different from the account specified for other services running in the same process”
Does anyone know what I can do to resolve this issue?
Thank you Brother. My laptop has net access after execution of your demonstration. Thanks once again.
What are you supposed to do when only one of the commands shows up completed successfully?
When I typed in the second command for local group administrator into at local service the syntax of this command said net local group group name comment text domain then it said group name add comment tax delete domain then the third line set group name empty parentheses that says add delete domain what does that mean?
Error 5: Access is denied. I have windows 7. Can anybody help plz
Worked perfectly.! For those having issues, make sure you are typing he script correctly.!
Thanks !!!
HELP.!!!!
Although the steps gave me access to the internet, it has caused mulitple problems. I can no longer click on my notifications on the start bar or click on the start menu. The start menu button on the computer will not pull it up either. I can not watch any videos that I have saved on my computer. It brings up a pop up that says “windows cannot find “”. Make sure you typed the name correctly, then try again. I truly need some help. I feel like I have gotten schemed. Should have done more research. Hopefully I can figure out a solution…
I have the same problem but I tried both two methods non of them work it shows me (system error 5 has occurred)
Please help me to fix this problem.
Thank you, worked first time 🙂
After each command iam getting this result” The syntax of this command is:
NET LOCALGROUP
[groupname[/COMMENT: “text”]] [/DOMAIN]
groupname {/ADD [/COMMENT:” text “]: /DELETE} [/DOMAIN]
groupname name […] {/ADD : /DELETE } [/DOMAIN]
HOW DO I proceed?
Result of your command telling you are missing parameters and have to type complete command. Please see the step-5 in the guide for complete command syntax. If you still have any question please reply, Thanks.
I did all the steps, Yes the service status says “Stopped” How do i change it to “Running” Status? please help
Thank you so much. This solved my problem.
Thanks Man, it really helped! i had wandered around before i came across your article. it was indeed great. Thanks.
I have a sony viao unltrabook. model SVT1311A11L.
It had been a nigthmare since I bought it new years back.
Now it wont go online. As per above: Diagnositc Policy Service and when I try to start it I get Error 5:Access Denied messge.
What can I do? Please help.
Thank you so much. It worked. I had the exact same problem.
thanks a lot .my internet is now working but the another step of checking if the service status has to be “Running” .it’s showing” stopped” instead. does it gonna affect my network thing any longer?
It worked!
Thanks a bunch. You saved the day…?
My service status is stopped. So i try to hit the start button. Then came out this: error 1053: The service did not respond to the start or control request in a timely fashion..idk what to do next..
It didn’t work, but then it did.
I tried the commands as shown a few times and repeatedly got error messages. Hmmm. So I changed both commands from /add to /delete and they were successful.
Then I used the /add commands as shown and they worked the first time.
So thank you very much for putting me on the right path. This was on an old HP Pavilion m7-1015dx
entertainment laptop running Windows 7.
Thanks alot bro! It worked
I am in the services.csm and instead of it being a command for windows it pops us as command for a user and then it denies the command. Any help in fixing this would be great!
thank you i did it
i have tried but still getting the same message Policy service not running
Omg!!!!!!!!!
DUUUUUUUUDE!
I haven’t been able to connect to the internet for over a month after a stupid windows update. I tried everything. Absolutely everything. I even restored my computer 5 times.
So freaking frustrating.
The. I found this and INSTANTLY after I followed the steps it connected. I didn’t even need to restart the darn thing
Thank you so much and I swear! This is my LAST laptop ever. I’m getting a Mac.
Every single time there’s a Windows update something gets messed up. I just spent 200 bucks to fix it not longer ago and I refuse to put more money In This thing. I was actually about to just throw it out and i found your instructions. Thank you so so so so much
Problem Solved !!!
It’s the second time I confronted this issue on Windows 7 Diagnostics Policy Service.
But this time around the fix was to first “Delete” the two commands one by one.
net localgroup Administrators /delet networkservice
net localgroup Administrators /delet localservice
Then do a “Restart”, open the Command Prompt as “Administrator” and put fix on place again.
net localgroup Administrators /add networkservice
net localgroup Administrators /add localservice
******This for sure will do the trick *******
Best regards to all
And thanks to TrickyWays writers for the solution.
Thank you ver much I hope all of your problems be solved.
Thanks so much for this solution! It worked perfectly first time and saved me having to get our work technician to come in and fix my laptop.
Well done, thanks a lot.
Don’t forget to run as adm 🙂
I was having the same issue with the error until I used this method.
go to start ,search and type:- cmd, right click on returned cmd.exe and select “run as administrator” at the prompt type:-
net localgroup Administrators /add networkservice
press enter then type:
net localgroup Administrators /add localservice
press enter then type:
exit
press enter and restart your computer
Open services and make sure the service is started.
Thank you for this very helpful methods!
perfect! Thanks, man.

Wow, this works a treat. So very grateful.
Tried checking the Diagnostic Service Properties but the Service status shows “Stopped”. I tried hitting Start but got the warning ⚠️ The Diagnostic Policy Service service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.
Can someone please help? Thanks!
Thanks, it worked for me. No problems connecting to the Internet!
This worked immediately — thank you. Losing internet (for no apparent reason) is so frustrating… you’re a lifesaver!

If you were here right now I would give you the BIGGEST hug. It worked and prob saved me tons of $. I had a tech from the cable co. and he couldn’t get it to work. I wish you had a way to leave you a donation, I def would.
OH! Wow! It ‘s work! Thank you very much.

This solution works perfectly. thanks team.
It worked the first time but now it does not work anymore. I have uninstalled and reinstalled the drivers from the menu, and retyped all of the commands multiple times. It wont allow me to force the diagnostic policy to start and i cant even recover the computer as it just stops and says it cant do it. Please help
Thank you So much Tricky Ways.. i can enjoy internet again
Updated to 1903, wouldnt get an ip address, dhcp and Diag policy service refusing to start, windows activation saying not activated, tried a couple of things incl chkdsk and sfc (both did repair found errors) running these to commands from an elevated cmd worked a treat thanks
Service status: Stopped how do I change it to say running, clicking on Start pulls up Error 5: Access is denied??? Help
Thank you so much.. I appriciate it
Thanks…it works
I went to Diagnostic Policy Service Properties…when I try to start the Service it says “Windows could not start the Diagnostic Policy Service on Local Computer.” Error 5: Access is denied.
Thank you so much! This works!
Thank you!
This may help you gain Internet access, but it is bad security in the long run and does not fix the bigger issues with the system.
Better to fix the root cause, which is almost certainly corruption in the system files. First do a recovery and restore latest automatic system restore point. Then after it boots, use sfc /scannow to repair system from earlier errors than restore point. If sfc doesn’t repair everything, run dism /online /cleanup-image /restorehealth, then reboot and afterwards run sfc /scannow again. In the end sfc /scannow should end with everything healthy.
Hi
I am trying to start the diagnostic policy service and it is not allowing me to do it and I get a message that says “Error 5 Access is denied”
I am enabling this because I can’t connect to the internet at all and my wireless connection says “Limited Connectivity”
Any help will be much appreciated
Thanks
First do a recovery and restore latest automatic system restore point, if successful then follow the rest of my comment above https://www.trickyways.com/2015/06/fix-diagnostics-policy-service-not-running/#comment-274217
