在浏览互联网时，您可能会遇到许多障碍，无法从理想的互联网连接中获益。这些可能是网速慢、无法理解网站要求等。无法访问互联网可能表明DNS存在问题，具体显示“ DNS 服务器未响应(DNS server not responding)”或“找不到服务器 DNS 地址(Server DNS Address could not be found)”，如下所示。当域名服务器(Domain Name Server)( DNS ) 无法解析网站 IP 地址时会导致错误。
问题的原因：(Causes of the problem:)
DNS缓存包含域名解析所需的信息，本质上它是被调用和解析地址的存储。当您浏览互联网(Internet)时，用户会在每个站点上留下您的访问和行为记录，保存在 cookie 或JavaScript应用程序中。他们的目的是在每次访问网站时为您策划您的偏好和个性化内容。
这些保存在DNS缓存中。DNS缓存包含域名解析所需的信息，本质上它是被调用和解析地址的存储。基本上，它使您的计算机能够更轻松地访问这些网站。
以下是DNS Server Not Responding Error发生背后的原因：
1. 网络问题：(1. Network Issues: )很多时候，可能不亚于互联网连接不佳的问题，可能是造成这种不便的原因，无意中归因于DNS。在这种情况下，DNS确实不负责任，因此在承担DNS错误负责之前，您可以转到“网络(Network)和共享中心”并运行故障排除程序。这将识别并修复许多常见的连接问题，并可以帮助您缩小问题的原因。
2. Common DNS Issues: TCP/IP: 最常见的DNS错误原因之一是TCP/IP软件或动态主机配置协议(Dynamic Host Configuration Protocol)( DHCP )，它为设备分配 IP 地址并处理DNS服务器地址。您可以通过简单地重新启动计算机来纠正这些问题（您也可以使用TCP/IP实用程序来修复您的设置）。最后，如果Wi-Fi路由器和您正在使用的设备都启用了DHCP，则不会导致问题。因此，如果其中之一未启用DHCP，则可能导致连接问题。
3. Internet Provider DNS问题：(3. Internet Provider DNS Issue: )许多Internet Provider将DNS服务器地址提供给他们的用户，如果用户没有故意更改他们的DNS服务器，问题的根源很可能是这个原因。当提供商的服务器超载或发生故障时，可能会导致“ DNS服务器无响应”错误或其他DNS问题。
4. 反病毒程序问题：(4. Anti-Virus Program Issues: )不幸的是，病毒和反病毒程序都可能导致DNS错误。更新防病毒数据库时，可能会出现错误，导致程序认为您的计算机已被感染，而实际上并非如此。反过来，这可能会导致尝试连接时出现“ DNS服务器未响应”错误。(DNS)您可以通过暂时禁用防病毒程序来检查这是否是问题所在。如果您的连接问题得到解决，则问题可能是由程序引起的。更改程序或简单地获取最新更新可以解决问题。
5. 调制解调器或路由器问题：(5. Modem or Router Problems: ) “ DNS 服务器(DNS Server)没有响应”似乎是一个难以修复的错误，但调制解调器或路由器的小错误也可能导致此类问题。只需(Simply)关闭设备并在一段时间后重新启动即可暂时解决问题。如果存在与调制解调器或路由器相关的问题并没有消失，则必须更换它。

How to Fix DNS Server Not Responding Error
While surfing the internet, you may encounter many hindrances in your way to derive the benеfits of an ideal internet connection. These cаn be slow internet speed, inabіlity to comprehend website requirements, and so on. The inabilitу to access the internet may potentially point out towards a problem of DNЅ, specіfically showing “DNS server not responding” or “Server DNS Address could not be found” as shown below. The error is caused when the Domain Name Server (DNS) is not able to resolve the website IP address.
Causes of the problem:
A DNS cache contains the information necessary for domain name resolution and essentially it’s the storage of called and resolved addresses. When you browse the Internet, the user leaves a record of your visit and behavior on each site, kept in cookies or JavaScript applications. Their purpose is to curate your preferences and personalize content for you, every time the website is visited.
These are kept in a DNS cache. A DNS cache contains the information necessary for domain name resolution and essentially it’s the storage of called and resolved addresses. Basically, it enables your computer to more easily reach those websites.
Here are the reasons behind the occurrence of DNS Server Not Responding Error:
1. Network Issues: Many times, it could be not less than a poor internet connection problem that might be responsible for such an inconvenience, inadvertently attributed to DNS. In this case, DNS is really not responsible and hence before assuming DNS errors responsible, you can go to your “Network and Sharing Center” and run the troubleshooter. This will identify and fix many common connectivity issues and can help you narrow down the cause of the issue.
2. Common DNS Issues: TCP/IP: One of the most common causes of DNS errors is the TCP/IP software, or the Dynamic Host Configuration Protocol (DHCP), which assigns IP addresses to devices and handles the DNS server addresses. You can correct these issues by simply rebooting your computer (you can also use a TCP/IP utility program to fix your settings). Lastly, if the Wi-Fi router and the device you’re working with are both DHCP enabled, it won’t cause an issue. So if one of them is not DHCP enabled, it can lead to connection problems.
3. Internet Provider DNS Issue: Many of the internet providers render DNS server addresses to their users, and if the users have not changed their DNS server intentionally, the root of the problem is more likely to be from this cause. When the provider’s server is overloaded or simply malfunctioning, it can lead to a “DNS server not responding” error or other DNS problem.
4. Anti-Virus Program Issues: Unfortunately, both viruses and anti-virus programs can lead to DNS errors. When the anti-virus database is updated, there can be errors that lead the program to think your computer is infected when it actually isn’t. This, in turn, can lead to “DNS server not responding” errors when trying to connect. You can check to see if this is the problem by temporarily disabling your anti-virus program. If your connectivity issue resolves, the problem likely arose by the program. Changing programs or simply getting the most recent update can rectify the issue.
5. Modem or Router Problems: “DNS Server not responding” seems to be an error arduous to fix but minor errors with your modem or router can lead to such a problem too. Simply switching off the device and starting it again after some time can fix the problem temporarily. If there is a problem associated with the modem or router that does not go away, then it must be replaced.
How to Fix DNS Server Not Responding Error
Here are some solutions to how you can fix the problem concerning DNS Server.
Method 1: Correct your DNS Server Address
The problem might arise from your incorrect DNS server address, so here’s what you can do to fix the problem:
1. Press the Windows logo key + R at the same time on your keyboard to open the Run box.
2. Type Control and press Enter.
3. Click on Network and Sharing Center in Large icons.
4. Click on Change adapter settings.
5. Right-click on Local Area Connection, Ethernet, or Wi-Fi according to your Windows and then, click on Properties.
6. Click on Internet Protocol Version4(TCP/IPv4) then Properties.
7. Make sure to checkmark “Obtain an IP address automatically” and “Use the following DNS server addresses”. Then use the following configuration:
Preferred DNS Server: 8.8.8.8
Alternate DNS Server: 8.8.4.4
8. Click Internet Protocol Version6 (TCP/IPv6) and then Properties.
9. Tick on “Obtain an IP address automatically” and “Obtain DNS server address automatically” and then, Click OK.
10. Now, reboot your computer and check whether the issue has resolved or not.
Method 2: Flush your DNS cache and reset IP
Apart from ensuring proper connectivity, you might want to flush your DNS cache because of personal and security reasons, for every time the website is visited by you, information is stored in the form of cookies and Javascript applications, enabling to curate content based on your past activities over the internet which indicates that you might want the same type of content when you open the website again. Sometimes you might want to maintain secrecy, and for the same purpose blocking cookies and Javascript may not suffice, which in the end leaves flushing the DNS as the last option.
Steps to flush DNS:
1. Type cmd in Windows Search then right-click on Command Prompt from the search result and select “Run as administrator“.
2. Type the following commands in the Command Prompt Window and press Enter after each command as given below:
ipconfig /flushdns
ipconfig /registered
ipconfig /release
ipconfig /renew
netsh Winsock reset
3. Reboot your computer and check whether this solution helps in fixing the problem or not.
Method 3: Disable your Antivirus
As discussed earlier, the antivirus software in your computer might be the root cause of the problem you are facing in accessing a website over the internet. Temporarily disabling the software can solve the problem. If it works, you might want to switch to another antivirus software. Installing a third-party application for preventing viruses to invade the computer system can be a problem and hence disabling it might work in fixing the issue.
Method 4: Disable Secondary Connections
If your computer system is connected to more than one network connection, then disable the other connections while keeping only one connection enabled.
1. Click on the Start menu and search for “Network Connections”.
2. In the Network and Internet Settings window, select your connection type, like Ethernet, then click on Change adapter options.
3. Right-click on the other connection (apart from your active Wifi or Ethernet connection) and select “Disable” from the drop-down menu. Apply this to all secondary connections.
4. After saving the changes, refresh your computer and see whether the website you wanted to have access to opens.
Method 5: Update Network Adapter Drivers
1. Search for Device Manager in Windows Search then click on the top search result.
2. Expand Network adapters, then right-click on your Wi-Fi device(for example Intel) and select Update Drivers.
3. Next, select “Browse my computer for driver software.“
4. Now select “Let me pick from a list of device drivers on my computer.“
5. Try to update drivers from the listed versions.
6. If the above didn’t work then go to the manufacturer’s website to update drivers: https://downloadcenter.intel.com/
7. Reboot to apply changes.
Method 6: Disable IPv6
1. Press the Windows logo key + R at the same time on your keyboard then type Control and press Enter.
2. Click on Network and Sharing Center in Large icons.
3. Click on Change adapter settings.
4. Right-click on Local Area Connection, Ethernet, or Wi-Fi according to your Windows and then, click on Properties.
5. Make sure to Uncheck “Internet Protocol Version 6 (TCP/IPv6)” then click OK.
Again check if you’re able to Fix DNS Server Not Responding Error, if not then continue.
Method 7: Reset your Router
Sometimes the Wi-Fi router might not work due to minor technological problems or simply due to some damage or a high load of data causing disruptions in its proper working. All you can do is simply restart the router, by disconnecting it from the power supply and switching it on after some time, or if there is an “On/Off” button on the router, you can press it and then turn it on again. After restarting, check whether it helps to resolve the problem or not.
You can also reset the router, by opening its configuration web page and finding the “Reset” option, or by simply pressing the reset button more nearly 10 seconds. Doing so will reset the password too.
