How to Fix the “DNS Server Not Responding” Error? 

When browsing the internet, there is nothing more frustrating than encountering the “DNS server not responding” error. This error can prevent you from accessing any website, leaving you unable to browse the internet or complete online tasks. However, this error is not a permanent problem and can be fixed with some troubleshooting steps.

Domain Name System (DNS) servers play an important role in connecting you to websites. They translate human-friendly domain names into IP addresses, allowing your computer to connect to the appropriate web server. Without DNS servers, browsing the internet would be a difficult and confusing experience.

In this article, we will discuss the steps you can take to fix the DNS server not responding error. We will cover a range of troubleshooting methods that can help you diagnose and solve the problem. By the time you finish reading this article, you will have a clearer grasp of how DNS servers operate and what you can do to resolve common problems.

What is a DNS server?

A DNS server is a computer server that stores and manages domain name system (DNS) records. DNS servers translate domain names into IP addresses, allowing computers to connect to the appropriate web server. 

When you type a website’s name into your browser, your computer contacts a DNS server and requests that it translate the name into an IP address. Once the DNS server has identified the IP address, it returns it to your computer, enabling you to connect to the website.

There are two types of DNS servers. Your internet service provider (ISP) employs Recursive DNS servers to resolve domain names on your computer’s behalf. Meanwhile, Authoritative DNS servers are responsible for storing and administering DNS records for a particular domain name.

How do DNS servers work?

DNS servers use a hierarchical system to manage domain names and IP addresses. At the highest point of the domain name system (DNS) hierarchy are the root DNS servers. They have a critical role in managing the top-level domains (TLDs), which include well-known ones like .com, .org, and .net.

In essence, they act as the ultimate authority on the internet and ensure that all the different parts of the DNS system are working together seamlessly. Without these root DNS servers, the internet as we know it would not be possible. Beneath the root DNS servers are the TLD DNS servers, which are responsible for managing the domain names within their TLD. 

When your computer sends a request to resolve a domain name, it starts by querying the root DNS server. The root DNS server responds with the IP address of the appropriate TLD DNS server. 

Your computer then queries the TLD DNS server, which responds with the IP address of the authoritative DNS server for the domain name. The authoritative DNS server then responds with the IP address of the web server hosting the website.

What Causes the “DNS Server Not Responding” Error?

There exist several causes that could trigger the error message “DNS server not responding”. Presented here are some of the most frequent factors that might engender this issue:

Inappropriate DNS settings: If the DNS settings on your device are inadequate, it will not be able to establish a connection with the DNS server. This could occur if you had previously modified the DNS settings, or if an automatic software update had made the alteration.

Issues with the router or modem: The difficulty with connecting to the internet could arise from the router or modem. A malfunctioning or improperly configured router/modem could result in your device’s failure to establish a network connection.

Presence of malware or viruses: The interference of malware or viruses with the internet connectivity of your device cannot be overemphasized. These dangerous agents could modify your DNS settings, restrict your access to specific websites, or trigger other network-related anomalies.

Troubles with the DNS server itself: The DNS server may be susceptible to issues that could lead to unresponsiveness to your device’s requests. This might happen if the DNS server is down, or it is experiencing a high volume of requests that could overwhelm its processing capacity.

Troubleshooting DNS Server Not Responding Error

If you are experiencing the DNS server not responding error, there are several troubleshooting steps you can take to resolve the issue. Here is a step-by-step guide to troubleshoot the error:

Checking internet connectivity and network settings

The first step in troubleshooting the DNS server not responding to errors is to check your internet connectivity and network settings. Make sure that your modem and router are both connected to the internet and that all cables are securely plugged in.

You should also check your network settings to make sure that your computer is configured to obtain an IP address and DNS server address automatically. To do this, go to your network settings and select the option to obtain an IP address and DNS server address automatically.

Flushing DNS cache

If your internet connectivity and network settings are both working properly, the next step is to flush your DNS cache. The DNS cache is a temporary storage area where your computer stores DNS information to speed up future requests. Sometimes, the DNS cache can become corrupted, leading to the DNS server not responding to errors.

Follow these steps:

1. Open the Command Prompt as an administrator. To perform this task, you need to do a right-click on the Command Prompt symbol and then choose the option “Run as administrator.”
2. You can execute the command “ipconfig /flushdns” by typing it in and then pressing the Enter key.
3. Wait for the confirmation message that says “Successfully flushed the DNS Resolver Cache.”
4. Restart your computer and try accessing the website again.

Changing DNS server settings

If flushing the DNS cache does not resolve the DNS server not responding error, the next step is to change your DNS server settings. Your computer may be configured to use the wrong DNS server or the DNS server may be experiencing an outage.

To change your DNS server settings, follow these steps:

1. Navigate to your network settings and choose the option to set your DNS server address manually.
2. Enter the IP address of a public DNS server such as Google DNS (8.8.8.8) or OpenDNS (208.67.222.222).
3. Save your changes and restart your computer.

Disabling firewall or antivirus software

If the DNS server not responding error persists, the next step is to disable your firewall or antivirus software temporarily. Your firewall or antivirus software may be blocking access to the DNS server, causing the error to occur.

To disable your firewall or antivirus software, follow these steps:

1. Open your firewall or antivirus software and locate the option to temporarily disable it.
2. Disable the software temporarily and try accessing the website again.
3. If the website loads successfully, you may need to reconfigure your firewall or antivirus software to allow access to the DNS server. Consult the software documentation for instructions on how to do this.

Resetting TCP/IP stack

Resetting the TCP/IP stack can also help resolve the DNS server not responding error. The TCP/IP stack refers to a group of protocols that regulate the way data is sent and received across the internet. Sometimes, the TCP/IP stack can become corrupted, causing internet connectivity issues.

To reset the TCP/IP stack, follow these steps:

1. Open the Command Prompt as an administrator.
2. Type the command “netsh int ip reset” and press Enter.
3. Wait for the confirmation message that says “Successfully reset the TCP/IP stack.”
