SOLVED  DNS Server Is Not Responding

No truth is absolute and when we talk about the famous error “DNS server is not responding”This concept applies perfectly. It has ever happened to all of us that we are browsing on our computer and suddenly or after a reboot the connection just doesn’t work, and the only explanation that the browser gives us is that message.

This little phrase is capable of filling us with dread, because nobody likes to be left without their internet access, so we started to find out what is happening with our connection, maybe we rebooted the router without any apparent solution and that’s when we feel a bit of despair.

As we said at the beginning, no truth is absolute and to solve this problem there are many truths, but to find the correct solution we must first understand what is DNS server and what function does it have, to find out read this post.

What is the DNS server?

What is DNS server

The domain name system (DNS) is responsible for converting domain names into numerical addresses or IPs, this is a decentralized system distributed on servers all over the world.

We surf the Internet and through different web pages, because our computers have the ability to connect to the DNS server to see which direction we are entering. The DNS server has the function of decoding IPs to give us the domain in an accessible way.

In other words, it’s a monumental decoder because all the computers and devices that navigate go to it to access the different sites in the form of host and not IPs.

A small example would be that instead of writing an IP like 70.304.899.100 we just write Google.com and click “Enter” 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 in an IP address and responds to the message generating the page we were looking for on the screen.

What are the reasons why DNS failure occurs?

As we have already been mentioning, no truth is absolute, so we cannot 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 are going to try to approximate the answer with these possible causes.

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

But calm that then we will tell you what you can do from the comfort of your home to solve this problem.

Solution to the error message “DNS server not responding”

As usual we connect to the Internet through a WiFi connection and without knowing why, from one day to the next when accessing it, a message may appear highlighting the following: “DNS server is not responding“.

Consequently, we spend hours looking for the possible solution to this problem, but this will no longer be necessary because In this article you will find all the possible solutions and tricks to solve the problem.

Change browser

We are going to discard all the problems in a very simple way and for that the first thing you have to do is change the browser, if as simple as that. If you are browsing in Google Chrome switch to Mozilla or vice versa, and if you are in another browser it is time for you to migrate to any of these 2 because they are the most recommended.

*Note: In the event that there is internet with a browser, and with another not, the solution is the one that comes next.

Restart the computer / router devices

If the problem persists it is time to try restarting the deviceIt is a universal law that almost all problems are solved by restarting the computer. But If the DNS server is still not responding, then you will have to try turning off the Router and giving it a little break to turn it on again, if after this the problem is solved well for you.

*Note: If not and the problem is still latent then we have to get a little more serious.

Clear the cache

The method that we are going to present you now is a universal solution, with this you will get clear all cache of computer connections, because as we mentioned previously it is possible that it is saturated with malicious files and this makes the response from the DNS server completely difficult.

To solve this we must do the following:

  • Do a little search on your computer and open the program “Run”.

run windows

  • Will write the letters “Cmd” in the program run and you will click on “To accept”.

run cmd command

  • In the system program that opened, you will type “Ipconfig / reread” and you will press Enter.

command ipconfig reread

  • Something like this will come out.

command to clear the ipconfig cache reread

  • After this you will do the same again, but this time you will write “Ipconfig / renew” followed by Enter.

ipconfig renew command

  • This will return the following. Consequently the problem should be solved with the caching system renewed and fully operational.

command to clear cache ipconfig renew

This method has its ace up its sleeve, in case what you have done so far does not work, you can try writing “Ipconfig / flushdns” and equally “Ipconfig / registerdns”, These last two commands are used to restart the internal DNS of your computer, and in case the problem with this is there, it will end up being solved.

If at this point the problem is far from being solved, then it is very likely that we are facing a failure of your internet connection provider, so we recommend you contact that company to see what solutions they offer you, or perhaps call a technician to check your connection.

Other alternative methods to fix it when DNS servers are down

Now do not despair, we still have other alternative methods that could give you the same result and also save you some money.

Disable firewall

It is possible that the Windows firewall This blocking some ports necessary for communication between computer and server. This is why by deactivating it we can restore the internet connection.

This method works, but we leave it for the alternatives because it can be said that we are leaving the computer a little vulnerable, since the firewall takes care of a certain part of the protection of the computer.

But it is not to be alarmed either, because on occasions we have used this method and nothing has happened.

  • Access the menu “Setting” in start and enter where it says “Update and security”.

update and security menu

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

windows menu firewall and network protection

  • On the next screen something similar to this will appear and what you are going to do is disable the “Domain Network” firewall and the “Private network”. The other will be left active as a means of protection in case of connecting to an unknown network.

disable the firewall of the domain network and private network

  • With this we should solve the problem, in case it was through the firewall that we were not browsing.

Change DNS manually

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

  • Open the “Internet and network configuration” from the lower right corner of the screen and right click on the connection icon that depends on the connection you use, in our case “WIFI”.

network and internet settings

  • Click where it says “Change adapter options.”

change adapter options

  • Again you will right click where it says “Wireless network connection” if your connection is for “WIFI”, or where it says “Local Area Connection” if your connection is by cable. There click on “Properties”.

local area connection properties

  • Then you will enter “Properties” of the “Internet Protocol version 4 (TCP / IPv4)”.
  • Change the DNS server address just like in the image below, from automatic to manual. In “Preferred DNS server” you will place “8.8.8.8” and in “Alternate DNS server” “8.8.4.4”.

 change DNS server address

  • After this there is only “To accept”, with this new configuration if the problem was in this then it will already be perfectly solved. Should the problem continue, there is still an ace up your sleeve.

Disable the Microsoft Virtual Mini Port Adapter

This port is only for exclusive uses of some Windows virtualization services, But when deactivated it does not cause any significant change, how do we deactivate it?

  • Run as administrator the “Cmd” or command prompt, just as seen in the image.

run the cmd as administrator

  • Type in command prompt “Netsh wlan set hostednetwork mode = disallow” and press “Enter” and then close.

command netsh wlan set hostednetwork mode = disallow

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

We hope that all these methods have helped you And if this was not the case, we recommend you contact your internet provider or a technician again to see what solution they give you.
