BEST FIX: Fix Error dns_probe_finished_bad_config

dns_probe_finished_bad_config prevents you from accessing websites, causes issues with connecting to outside services. As the name suggests, this is a DNS related error. The function of DNS is to resolve/translate names so when your system cannot resolve or translate the address, you will get this error or DNS_PROBE_FINISHED_NXDOMAIN

By default, your computer is set to use the DNS configured in your router or modem which is Internet Providers DNS unless it has been changed. I always recommend using public dns servers, which you should  see  in this guide as they are most active and have a 99% uptime. If you don’t understand, don’t worry, just follow the steps below.

To fix this issue, follow the steps below:

Hold  Windows key and press R

In the run dialog, type cmd and click OK

When the Black Command Prompt opens, type the following in it and Hit Enter.

ipconfig /flushdns


This will flush dns cache. Which is sometimes, the cause when there is a change in the DNS and the system is looking up its local cache to take you to the websites.

Once this is done, Hold  Windows key and press R again.

This time, type ncpa.cpl and Click OK.

You will be taken to the network connections.

What we need to do here, is update your DNS settings.

Identify your network adapter, which is connected and right click it, then choose Properties.

PRO TIP: If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Reimage Plus by Clicking Here


Then, from the properties pane, click “Internet Protocol Version 4 (TCP/IPv4)” once so that it becomes highlighted in grey and select Properties again.


Put check on use the following dns server addresses and enter the following for Preferred DNS Server and Alternate DNS Server

Preferred DNS SERVER:
Alternate DNS SERVER


Click OK and close the rest of the windows.

    it works only for few min(max 1 hour) and again starts the same problem even though above DNS settings changed.There are multiple fixes again on the web but nothing works for more than a day .Issue repeats again.

    • Looks like a program on your computer changes the settings. Which firewall/antivirus software are you using?

      • Eswar Koneti

        sorry for late reply.I Use default anti virus comes with windows called windows defender.Firewall is windows firewall which is ON.Those settings what i changed with IP address in DNS still same appear when i recheck the TCP IP properties.Something seems to be happening.

    Why do we type in and What does that do exactly?

    • It is a public dns server always up, and resolves names faster then the ISP’s dns.

  • Jenny

  • Yomna Ashraf

    this method worked with me thankssss alot ^^

  • Tapia Cadillo Rommel

    Excellent my friend!!!

  • Nick

    I can’t believe how fast internet goes after applying fix. How long will it last?

  • It will not make the system prone to vulnerabilities; so all is well using the public dns.

    • Giovanni Cerri

      Ok, and about performance, the public dns provided by Open DNS are also as good as Google public dns?

      • I prefer Google DNS as it is more reliable with almost no down time.

  • Julie Waterfall

  • himanshu bhawankhel

    Hi Dear
    I have tried the same for my Laptop (windows) and the problem resolved but the same problem still exist in Anrdoid mobiles connected to wifi network.
    Please help

    • You can try a hardboot on your Android or change it’s DNS to the public DNS names from it’s network settings.

  • TheNapkinGuy

    I know -_-

  • Skater

    It worked at first but after i shut down my laptop and the internet and turn them on the next day it not working anymore, i repeat the steps but nothing happens. The troubleshoot result stated that my computer appears to be correctly configured, but the device or resource (DNS server) is not responding. Is that mean i have to change something on my internet setting? Pls help, im desperate.

    • Update the DNS to and as stated above. If you already have done this, then please re-do and check. Also disable your Antivirus & Any Internet Security Programs.

  • UUB

    I tried … but no reaction on the ‘ncpa.cpl’ command. I also can’t open the networkproperties. The PC is not reacting. What can be wrong?

    • No reaction to the commands indicates something else may be wrong? Does it responds to anything at all, mouse click, browser opening etc?

      • Wim Beelen

        Yes, the pc is reacting to everything, except not when I want to open the network properties.

  • Corey

    Once I get to the WiFi properties I have an iPv6 not an iPv4. It then reads that the two suggested DNS servers are invalid. What can I do from here?

    • Use these:

      Primary: 2001:4860:4860::8888
      Secondary: 2001:4860:4860::8844

  • Roxstar Rishabh

    It worked for 4 days then again it shows the same problem!! can i get a permanent solution pls???

    • The solution is permanent, one of your programs is probably pushing the change in settings. I’d suggest doing a clean boot.

  • Krishan

    It’s working, thnku bro

  • Helene

    Thank you for the simple steps… Truly appreciate the knowledge to self help with out the frustrations.. Extremely happy internet user.

  • jasrockett

  • ze_captaincabs

    Thank you so much! Man, quite a number of probs popping out of my laptop since the win10 update.

  • GqrlicBreqd

    it worked at first, but then when i restarted my pc it happened again

    • This indicates that something on your PC is changing the settings. I would suggest a clean boot.

  • Julian

    Thanks!!! I had this problem for the longest time and always assumed that it was because I had a very old wireless router, this worked!

  • Jimmy Campbell

    Been having this same issue for about a month. It’s only when I use my surface pro 3 on my home network (Time Warner Cable) They say it’s an OS issue, and recommended this page to fix. It didn’t change anything. (And I’m sure it’s coincidence, but it seems worse.) Anyone else have this not fix their issue then find another?

    • You must have installed something on your surface which is resulting in this error, try doing a clean boot and disable/uninstall any apps recently installed after which the issue started.

  • Koh Sing

    Hi, it work for me. Thanks

  • Lior

    It fixed my problem. Thanks!!!!

  • Katie Arbuthnot

    i am getting this error on all my devices when it connects to our home router, but doesnt happen when we connect to other wifi’s do you think this is the same problem?

    • Please reset your router and then try. The reset button is located on the back of the router which needs to be held for 6 to 10 seconds.

  • Tyler

    Thanks this was very helpful!

  • Have you tried changing DNS? Also who is your Internet Provider?

  • Jess

    Each time I update the DNS settings on my Windows 7 computer to use and the result is I cannot get to any web site. When I revert back to “Obtain DNS server address automatically” I can get to all web sites except the one that displays DNS errors every few days. Is there something else I can check that might be blocking the use of and

    • If it’s just one site, then its the issue with the site, you do not need to use 8.8 and 4.4. which site is it?

      • khush

        i can use all other like google youtube and facebook but wen i am trying to load, torrentz website to download using utorrent so i need to set this dns aur other if this dns work would it give problem to other sites
