Windows phone lỗi cannt find server or dns error năm 2024
So being denied access to the internet when you are trying to mine nuggets of valuable information from your go-to web sites can be quite an ordeal. Especially when you are under pressure to complete a piece of urgently required work. Show
One particularly unwelcome cause of being denied access to the internet is the “DNS Server Not Responding” error. It’s like that old fable where a troll sits under a bridge and says “You shall not pass!”, or something about gobbling up those that wish to cross the bridge. I’m happy to tell you that you should be able to defeat the troll and cross the bridge to internet access joy by following the simple trouble shooting steps discussed in this article. The “DNS Server Not Responding” error is a fairly common issue and is generally easy to fix. There are many reasons why this issue may occur. But fundamentally it is caused because the DNS server that is contacted during the processes of loading a web page is unable to find the site that contains the web page that you have requested. This article explores what may have triggered this issue to occur and how you may go about fixing the issue. Firstly, I think it is a good idea to gain at least a basic understanding of the “DNS Server Not Responding” error. To do this, let’s first understand DNS. DNS stands for Domain Name System. A simple explanation of DNS is that it is a decentralised storage of human readable internet addresses, like the ones with which you will almost certainly be familiar (for example www.amazon.com or www.netlix.com). The DNS maps these human readable URLs to their appropriate IP (Internet Protocol) addresses. IP addresses are much less human readable, but are essential for the inner workings of the internet. IP addresses uniquely identify computers on the internet. The IP address associated with the URL, www.netflix.com, might for example, look like this, 69.53.224.255. It is clearly easier for you to remember “www.netflix.com", rather than a string of numbers delimited by full stops, when you wish to access your favourite content on Netflix. So the DNS facilitates this for you, so that you don’t have to remember or manually lookup unfriendly strings of numeric data every time you wish to access a web site. The common analogy to explain DSN is a telephone directory. Basically, as you would look up a telephone number using the name of the person you wish to call in a telephone directory, a similar look up is performed when you type in the URL (like www.amazon.com) of the web site you wish to view within your browser. Thankfully you don’t have to manually look up the corresponding IP address for www.amazon.com, as this is performed behind the scenes for you automatically. So the appropriate IP address is retrieved automatically every time you type in a URL into your browser. This IP address is then used to contact the appropriate server that hosts the relevant web site associated with the URL you have entered into your browser. When the “DNS Server Not Responding” error occurs, this means that the decentralised naming systems responsible for automatically looking up the appropriate IP address based on the relevant hostname that you entered into you browser fails to respond. There are many reasons why this error occurs, but fortunately there are also many solutions available to you to fix the issue. An easy solution may be to simply change the web browser you are using or even simpler still, simply restart your computer. Yup, simply turning it off and then turning it on again could fix the issue. However, if you are not so lucky and the problem still persists, don’t despair – there are many steps that you can take to find out the cause of the issue and subsequently fix it. In this article you will learn a number of possible solutions to the “DNS Server Not Responding” error.

Disable all Network Connections Except for the Connection that you are UsingDisabling the additional network connections you may have setup on your computer (other than, for example, the Wi-Fi connection that you are using to access the internet) might fix the “DNS Server not Responding” issue. To disable the relevant network connection, follow these steps:
Restart your Computer in Safe ModeWhen you start your computer in Safe Mode, this means the Windows operating system loads with a limited set of drivers and files. This can help you diagnose what is causing your “DNS Server not Responding” issue through a process of illumination (as it were). So to start your PC in Safe Mode, follow these steps:
Try to access the web site that resulted in you getting the “DNS Server not Responding” issue. If the problem does not occur in safe mode this means that additional software may be the cause of the issue. You can uninstall any additional software from your PC, one by one, and then test to see if the issue still occurs. If the issue does not occur after uninstalling particular software, this means that it is likely that this software was interfering with your internet access.
