What to do if the DNS server is not responding and how to fix it? Step by step guide

No truth is absolute and when we speak of the famous error " DNS server is not responding This concept applies perfectly. It has happened to all of us that we were browsing our computers and suddenly or after restarting a session the connection just does not work, and the only explanation the browser gives us is this message.

This little phrase is able to scare us, because no one likes to lack access to the internet, so we start to find out what is going on with our connection, peut - being that we restart the router with no apparent solution and that's where we feel a little bit of desperation.

As we said at the beginning, no truth is absolute and to solve this problem there are many truths, but to find the right solution, we must first understand what is DNS server and what he does, to know how to read this article.

What is the DNS server?

The Domain Name System (DNS) is responsible for converting domain names to numeric or IP addresses, it is a decentralized system distributed on servers around the world.

We surf the internet and different web pages because our computers have the ability to connect to the DNS server to see which direction we are heading. The function of the DNS server is to decode the IP addresses to give us the domain in an accessible way.

In other words, it it is a monumental decoder because all the computers and devices that browse it access it to access the various sites in the form of hosts and not IP addresses.

A small example would be that at instead of writing an IP address like 70.304.899.100, we just write Google.com and press » Starter " to navigate. Then our device sends a message in the form of a host or domain name, the message reaches the DNS server, decodes it into an IP address and responds to the message generating the page we were looking for on the screen.

What are the reasons that DNS failure occurs?

As we mentioned before, no truth is absolute, so we can't know exactly why our DNS server stops working overnight. At the moment, the only thing we know is that if there is no good communication between the server and the device, there is no internet browsing, anyway we will try to approach the answer with these possible causes.

It is possible that the servers are attacked by various factors, among which we can mention that your browser has a large number of caches with malicious content, that the servers are simply saturated or not properly fed with a good internet connection , possibly also There are software problems, with the router, or they are just too slow to respond.

But rest assured that ci - below we will tell you what you can do from the comfort of your home to solve this problem.

Solution to the error message "The DNS server is not responding"

Most of the time we connect to the Internet via a WiFi connection and without knowing why, overnight when accessing it, a message may appear highlighting the following: " DNS server is not responding .

Therefore, we spend hours looking for the possible solution to this problem, but it will no longer be necessary because in this article you will find all the possible solutions and tips to solve the problem.

Change browser

We will eliminate all the problems in a very easy way and for that the first thing to do is to change browsers, if it is that easy. If you are browsing in Google Chrome, switch to Mozilla or vice versa, and if you are in another browser then it is time for you to migrate to one of these 2 as they are the most recommended.

Restart the router computer / devices

If the problem persists, it is time to try to restart the device It is a universal law that almost all problems are solved by restarting the computer. More if the DNS server is still not responding, you will have to try shutting down the router and giving it a short break for turn it back on , if after that the problem is solved for you.

Clear Cache

The method that we are going to present to you now is a universal solution, with this you will be able to clean all cache computer connection, because as we mentioned before, it is possible that it is saturated with malicious files and this completely hampers the response from the DNS server.

To solve this problem, we need to do the following:

• Do a little search on your computer and open the program "Execute".

• You will write the letters "Cmd" when launching the program and you will click on "OKAY".

• In the system program that opened, you type "Ipconfig / reread" and press "Entrance".

• Something similar will come out.

• After that you will do the same again, but this time you type "Ipconfig / renew" followed by Enter.

• This will return the following. Therefore, the problem should be solved with the updated and fully operational caching system.

This method has its trump card up its sleeve, in case what you've done so far doesn't work you can try writing "Ipconfig / flushdns" and also "Ipconfig / registerdns", these last two commands are used to restart your computer's internal DNS, and if the problem is there, it will eventually be resolved.

If at this stage the problem is far from being solved, it is very likely that we are facing a failure of your Internet connection provider, so we recommend that you contact that company to see what solutions they have for you, or maybe call Ask a technician to check your connection.

Other alternative methods to resolve this issue when DNS servers are down

Now don't despair we still have other alternative methods which could give you the same result and also save you money.

Disable the firewall

It is possible that the windows firewall blocks certain ports necessary for communication between the computer and the server. Therefore, by disabling it, we can restore the Internet connection.

This method works, but we leave the alternatives because we can say that we leave the computer a little vulnerable, since the firewall is responsible for some part of the protection of the computer.

But this is not to alarm us, because we have sometimes used this method and nothing happened.

• Access the menu "Settings" at startup and enter where it says "Update and security".

• Then in the menu you will click where it says "Windows Security" then "Firewall and network protection".

• On the next screen something similar will appear and what you are going to do is deactivate the "Domain network" firewall and the “Private Network”. The other will remain active as a means of protection in the event of connection to an unknown network.

• With this we should fix the problem, in case it is through the firewall that we are not browsing.

Change DNS manually

This method is very efficient, for that there are two ways to get the DNS, one manually and the other automatically. By default, our computers automatically obtain DNS, and we can manually change to public DNS , in this case we will recommend Google 8.8.8.8 and 8.8.4.4 How to do this? Easy:

• Open them "Internet and network settings" in the lower right corner of the screen and right click on the connection icon which depends on the connection you are using, in our case "WIRELESS".

• Click where it says "Change adapter options".

• Again you will right click where it says "Wireless network connection" if your connection is by "WIRELESS", or there where it says "Network connection local" if your connection is by cable. There, click on "Properties".

• Then you will enter "Properties" de “Internet Protocol Version 4 (TCP / IPv4)”.
• Change the DNS server address as in the image below, from automatic to manual. In "Preferred DNS server", you put «8.8.8.8» and “Alternative DNS server” “8.8.4.4”.

• After that there is only "OK", with this new configuration if the problem was there then it will be perfectly resolved. If the problem persists, there is still a trump up your sleeve.

Disable the Microsoft Virtual Mini-Port Adapter

This port is only intended for exclusive use of certain Windows virtualization services, but when deactivated, it does not cause any significant change. How to deactivate it?

• Run as administrator the "Cmd" or Command Prompt as shown in the picture.

• At the command prompt, type "Netsh wlan set sharednetwork mode = disallow" and press "Entrance" , then close.

The last resort we can use is to start Windows in safe mode , because it is designed to detect system imperfections and only uses the tools necessary for operation, avoiding unnecessary ones.

We hope all of these methods have helped you and if not, we recommend that you contact your internet service provider or a technician again to see what solution they provide.
