Surfing the Internet is one of the most common tasks we perform with our computers on a daily basis. As long as we’ve enabled the connection with our provider, this task shouldn’t be too difficult. However, on occasion, we may encounter an error message that we are unsure how to handle. This could explain the “DNS server is not responding” error.

If this error appears unexpectedly, we will be unable to access any website via the Internet. That is why, today, we will look at what the DNS server is, why this error may occur, and, most importantly, what we can do to resolve it.

What is the DNS Server

The domain name system (DNS) functions as the Internet’s phone book, converting numerical addresses or IP addresses into domain names. Its goal is to convert what a user types into their browser into something that a computer can understand and use to find a website. As a result, when we type a domain name like Google.es into our web browser, the DNS is responsible for determining the correct IP address for this site. Following that, the browser uses this address to communicate with the origin servers in order to access the information on the website. So we can say that the DNS servers are responsible for all of this.

Who is DNS Server Founder

In 1983, Paul Mockapetris invented the Domain Name System (DNS), which took the Internet beyond its academic roots. Mockapetris recognized the flaws in the early Internet’s (then ARPAnet) system of storing name-to-address translations in a single table on a single host while working at USC’s Information Sciences Institute (HOSTS.TXT). Instead, he proposed a distributed and dynamic naming system, similar to today’s DNS.

Instead of simply looking up host names, DNS created easily recognizable names for IP addresses, making the Internet far more accessible for everyday use. DNS became one of the original Internet Standards after the formation of the Internet Engineering Task Force (IETF) in 1986.

Why DNS Server Not Responding

When accessing a website, we may encounter certain DNS error messages, one of which is the message “The DNS server is not responding.” Because the DNS server cannot correctly map hostnames to IP addresses, our web browser is unable to connect to the site.

This error has no single cause, as it can be caused by anything from faulty network adapters to incorrect server addresses. It is also possible that the servers are overloaded, that we do not have a reliable Internet connection, or that there is a problem with the router. It could also be due to an issue with our antivirus software.

Fortunately, most of these problems are easily solved; however, because there is no single cause, we may have to try different approaches until we find one that works.

How to Fix Error DNS Server Not Responding on Windows

Here are the steps of How to Fix Error DNS Server Not Responding on Windows for you to read and follow. Follow the provided steps carefully.

Restart the computer as well as the router.

Because the simplest solutions are often the most effective, we will begin with the most basic, such as restarting our computer, before moving on to more complex tasks. If the problem persists, we proceed to restart the router, for which we must locate and press the power button to turn it off. We wait about five minutes for the router and its network to properly shut down. Later, we’ll turn it back on to see if that solves the problem.

Alter the DNS server

Another simple solution to this error is to change the DNS server manually. We will be able to circumvent the limitations and even obtain a faster Internet browsing speed from our device if we take this action. To accomplish this, we must switch our DNS server to a well-known, fast, and public DNS.

Change the DNS

In Windows 10, we can also access the System Configuration by pressing the Windows + I keyboard shortcut. Then, in the left column, select Network and Internet, and in the Status section, select Change adapter options. This will open the Control Panel, and we will right-click on our network to select Properties.

Select Internet Protocol version 4 (TPC/IPv4) and click Properties in the new pop-up window.

Finally, on the General tab, check the box labeled “Use the following DNS server addresses.” We enter 1.1.1.1 in the preferred DNS option and 1.0.0.1 in the alternative DNS server. Finally, we press the OK button to save the changes.

Update network drivers

It is critical to keep our network drivers up to date in order for our Internet connection to function properly, as they can be the root cause of certain problems if they become obsolete.

As a result, we will press “Windows + X” and select the Device Manager option from the context menu. We then expand the “Network adapters” section, right-click on the adapter we’re currently using, and select “Update driver.” We can either let Windows find a driver for us or select one that is already on our computer.

Once the new driver has been installed, we restart the computer and verify that the DNS server is operational.

Disable Internet Protocol version 6 (IPv6)

IPv6 is the most recent version of the Internet protocol that identifies devices on the Internet and on a local network. However, it could also be the cause of the DNS server not responding issue, so we can try disabling it if the previous steps do not resolve the issue.

To accomplish this, we return to the “Change adapter settings” section of the Control Panel’s network options. This opens a new window for us, and we right-click on the current connection. Following that, a context menu will appear, from which we can select the Properties option.

Next, we locate and uncheck the Internet Protocol version 6 (IPv6) option. Finally, press OK to save your changes.

Disable antivirus firewall

Antivirus and firewall software are designed to protect our computers from viruses and malware. These tools, however, can also block our Internet connection if they believe our computer is infected, which is why the error message “DNS server is not responding” appears.

As a result, we can temporarily disable our antivirus and firewall to see if they are the source of the problem. If we use Microsoft Defender as an antivirus, we must take the steps listed below. We type Windows security into the Start menu’s search box and navigate to the section “Firewall and network protection.” Within this menu, we will see three different sections, each with a green icon and a click on the drawing that corresponds to the title. We go through each one and deactivate it.
