The DNS_PROBE_FINISHED_NXDOMAIN issue stops you from reaching websites and causes problems with outside service connection. As it’s apparent from the name itself, this error is domain name system related. The main responsibility of DNS is to maintain lists of names. At the moment if your system is unable to translate or resolve the address, this error will appear.
Your computer will use the Domain Name System from your router by default, or the DNS from a modem belongs to your Internet Provider if it wasn’t altered. It’s always best to use public DNS servers. They are the most active ones, and their uptime is 99%, as you will see in this simple guide.
This guide will show how you can change the DNS from default or local to Google’s DNS.
You want to do this because Google’s DNS boasts a 99.99% uptime, and it is significantly more reliable than the Internet Provider’s DNS. So, when your DNS is slow, down or overloaded, switching to the public system can help solve your problem.
In order to do that, just follow this simple guide.
- Go to start menu and enter cmd in it.
- Right-click it and make sure to select to run it as an administrator. This will open the command prompt.
- When this happens you need to manually type in ipconfig/flushdnsdns_probe_finished_nxdomain-1. Once you do that, press Enter.
- After that step is over, open your network connections. You can do it by using the Run dialog, or manually. If you choose to use Win+R enter ncpa.cpl and press Enter.
- Find the active network adapter and open its properties (right click – properties).
- Choose Internet Protocol 4 and select it. You will then have the option to click on properties again. Do so.
- Change the setting for DNS addresses to “Use the following…”. In the first box enter 18.104.22.168 and in the second one enter 22.214.171.124. You can now click on the OK button and close the window.
DNS Geek Tool:
This should resolve most of DNS issues that might arise. As DNS Geek tool doesn’t have an SSL certificate, unverified publisher issues and prompts might come up. If you get a notification telling you that this script isn’t digitally signed, you can run the script after running this command: Set-ExecutionPolicy Unrestricted
When you’re done running this script, you can revert the setting to Restricted with this command: Set-ExecutionPolicy Restricted
If your computer has no internet access, download this tool to a different device and then copy it to a USB stick. Once you do that, connect the USB to the computer that’s experiencing DNS problems.
Simply copy the file from that USB, paste it on your Desktop. Then click Start, type cmd, and select Run As Administrator.
The Black Command Prompt window will open. Click and drag the tool file to it, hit Enter, and run it.
Also, you can do it by following the steps below, since DNS Geek Tool does the same thing that the guide bellow does.
