If you encounter an error message that reads “Error 105 (net:: Err_Name_Not_Resolved)” while surfing the web, here’s what you should do:

DNS lookup failed because the server Err_Name_Not_Resolved. Error Code 105 in Google Chrome is one of the most prevalent error codes, and the solution is simple. Is there anything else we can do?

Chrome displays Error Err_Name_Not_Resolved


It’s possible that the Chrome browser is to blame for some of this problem, but it’s also possible that your Windows PC is to blame. To make things easier for you, I’ve divided the steps into two parts. The first is for Chrome, and the second is for Windows.

Use the built-in Chrome Malware Scanner & Cleanup Tool in the Chrome browser. Removes unwanted advertisements, pop-ups and viruses as well as unusual startup pages, toolbars and anything else that may be clogging up your network.

1. Disable Google Chrome’s Prefetch

For example, Google utilises a prediction engine to help finish queries and URLs entered in the address bar. When you’ve already visited a website, it utilises that IP address to connect to it. At these times, it’s a good idea to turn it off.

Step 1: Open Chrome’s Settings menu. Search for ‘Prefetch’ in Privacy and Security.

Step 2: The ‘Use a prediction service to help complete searches and URLs typed in the address bar’ setting can be turned off by clicking on the corresponding checkbox.

Chrome needs to be restarted.

2. Troubleshooting a Computer Network

Frequently, your Windows PC is to blame for these issues. Since most people only use one browser, we won’t know if there is a problem with any other browser. Reconnect your network cables after you’ve performed step 1 and restarted your router

Oftentimes, these tips are the root of the problem. Make sure your PC or router’s cables are plugged in correctly. Make sure to reboot your router if you’re using WiFi. Finally, if you’ve already joined to a WiFi network, you may simply unplug and reconnect.

3. Uninstall The Proxy

Step 1: To launch Internet Properties, press Windows Key + R, then type “inetcpl.cpl” and press Enter. Next, pick the LAN settings under the Connections tab.

Step 2: Uncheck Ensure that “Automatically detect settings” is ticked when using a proxy server on your local area network (LAN). Restart your computer by clicking OK and then Apply.

For some reason Windows couldn’t figure out how to connect to this network’s proxy server automatically. Disable any third-party proxy services that you may be utilising.

4. Reset the DNS, Winsock, and TCP/IP 

DNS on your PC may still be storing the previous IP address, preventing websites from resolving. So, flush the DNS, reset Winsock, and reset TCP/IP to get the best performance out of your computer.

It’s possible to perform these three tasks with our shareware FixWin. The fourth step is to use Google’s Public DNS service. If that doesn’t work, you can try Google Public DNS. DNS IP addresses can only be used if you manually update your operating system’s DNS settings.

When it comes to altering your DNS settings, you don’t have to worry about the process; it differs depending on the operating system or device you’re using. We’ll teach you how to fix this problem on Windows in this article.

For the purposes of this essay, let’s assume you’re using a Windows PC and the Google Chrome web browser.

If your Internet or DNS settings are incorrect, Chrome may show a grey window with one of these messages. Every time you type in a domain name in a browser, DNS will seek up the domain’s IP address and return that information to you.

Step 1: The first step is to right-click on the taskbar Network icon and pick Network and Sharing Center from the context menu.

Step 2: “Change Adapter Settings” will appear. “Local Area Connection” or “Wireless Connection” are two possible choices for the network connection used to connect to the internet.

Step 3: Click Properties in the context menu that appears when you right-click on it. Click the Properties button in the new window to pick “Internet Protocol 4 (TCP/IPv4).” Select the “Use the following DNS server addresses” checkbox in the new window.

When you’re done, click the “Save” button to save your changes. Finally, click OK and close the application.

5. Disable Antivirus and Firewall 

The OS is protected by both of these. Response from such sites that are malicious or even considered because of false-positive results will be prohibited.

To check if it helps, try disabling both Antivirus and the Firewall. As a result, you will need to add those sites as an exception and then enable it. That’s a surefire way to get things done.
