DNS server is not responding in Windows: how to fix the problem

There is no doubt that Windows 10 is the most widely used operating system on computers. There are many users who use it in their day to day, both at home and in companies. Sometimes problems can arise that compromise good operation and even safety. In this article we are going to talk about what we can do if the DNS server is not responding. We are going to take a series of steps to correct this failure.

How to fix when DNS server is not responding in Windows

Keep in mind that any device when connecting to the Internet has to send a DNS request to a server. This allows the request to be redirected to the correct website. Hence the importance of always having good DNS servers. In case of using a bad one, that is slow, it will cause a delay when loading that site.

However, the problem may be greater than just the slow server. It could happen that the DNS server is not responding in Windows. This will directly mean that we will not be able to load a web page. We could have the Internet but without being able to access web pages. This means that we could safely ping any IP address, private or public, but we could not resolve the IP address of a partner domain, that is, we could ping but we could not ping because it would not resolve the domain, and therefore, we would not obtain the public IP address associated with a specific domain.

In case we run into this problem we have several solutions that we can take into account. We are going to show what are the main steps that we can do and in this way navigate normally.

Restart the router and system

A basic first step that we can take into account is to restart both the router and the system. In this way, on many occasions we can solve errors of this type that prevent us from connecting to the network or from being able to open pages correctly. Therefore, the first thing we will do is restart the computer.

If the problem persists, the next thing we are going to do (or we can do both at the same time) is reboot the router. Now, you have to do it correctly. It is not enough to switch the appliance off and on again. Ideally, keep it off for at least 30 seconds and then turn it on.

Forget the Wi-Fi network and reconnect

We can also try to forget the Wi-Fi network. This step is easy too. To do this, you simply have to go to the Windows taskbar, click on the Wi-Fi icon, select our network and give it a forget. Later we will reconnect. We will put the password again and we will check if this has solved the problem with the DNS server that does not respond in Windows.

If the loading of web pages still does not work, it is very possible that the WiFi network is collapsed if it is a wireless network of a university, hotel or cafeteria, we recommend you perform the typical “ping” to check if the DNS resolution or not, in case it works correctly, but the web pages do not load, it could be that you have very little available bandwidth, or that the WiFi network is collapsed.

Try a different browser

Are we still unable to open web pages? It is possible that the failure is due to the browser we are using. Maybe some extension that is malfunctioning, something that we have misconfigured or even some malware that is affecting.

In this case, what we will do is try any other browser. For example, if we are using Google Chrome, which is the most used, go on to test Mozilla Firefox and see if this way the pages open normally. It is possible that you do not have the browser properly configured and inadvertently have activated the Proxy service, and for this reason you cannot navigate normally through the usual web browser.

Disconnect the VPN

Another issue to consider is VPN tools. They are very useful and increasingly used, but sometimes they can interfere with the connection. If we see that the DNS server is not responding, we must take into account if we have a VPN installed.

What we will do is simply disconnect the VPN momentarily or connect to another server. This way we will check if the problem is solved and the websites open normally. It would also be highly recommended to make sure that our VPN program does not have the kill-switch activated, a feature that all VPNs have that allow us to “block” all traffic if we are not browsing through the VPN, in order to protect ourselves against to possible attacks.

See if any security program is blocking the connection

It could be that some security program is interfering. This is especially very common on firewalls. They could be affecting the connection and causing problems that prevent it from working properly. Sometimes it can be due to a bad configuration that we have made. Simply by changing some parameters we can solve it. In an extreme case, we can momentarily pause that security program and see if the same thing continues to happen or not.

Normally the firewall incorporated in operating systems such as Windows 10 does not block this type of traffic, unless you have specifically configured the firewall to create new rules, in this case, possibly by mistake, you have blocked yourself and cannot solve domains correctly because of this.

Try another device to rule out problems

In case all this that we have mentioned has not had any effect, we can try to connect with another device. In this way we can rule out problems with the Internet provider. If we can navigate normally on another computer, we rule out that this is the failure. We should also try to connect with this device both via cable and via WiFi, because it is possible that the culprit is the WiFi wireless connection.

In short, by following these steps that we have mentioned, we can solve the problem when the DNS server does not respond in Windows 10. As we have seen, they are simple steps that could help us avoid this failure.
