While 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 by following some troubleshooting steps.
The DNS servers play an important role in connecting you to websites. They translate human-friendly domain names to 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 context, we will discuss the steps you can take to fix DNS Server Not Responding error. We will cover a range of troubleshooting techniques that can help you diagnose and resolve problems. By the time you finish reading this article, you’ll have a clearer understanding of how DNS servers work and what you can do to troubleshoot 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 servers.
When you type a website name into your browser, your computer contacts a DNS server and requests that it translate the name to an IP address. Once the DNS server detects the IP address, it passes it back to your computer, enabling you to connect to the website.
There are two types of DNS servers. Your ISP employs recursive DNS servers to resolve domain names on your computer’s behalf. Meanwhile, authoritative DNS servers are responsible for storing and managing DNS records for a particular domain name.
How do DNS servers work?
DNS servers use a hierarchical system for managing domain names and IP addresses. The root DNS server is at the top of the Domain Name System (DNS). They have an important role in managing top-level domains (TLDs), including well-known domains such as .com, .org and .net.
In essence, they act as the final 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. Below root DNS servers are TLD DNS servers, which are responsible for managing domain names within their TLDs.
When your computer sends a request to resolve a domain name, it starts by asking the root DNS server. The root DNS server responds with the appropriate TLD DNS server’s IP address.
Your computer then queries the TLD to the DNS server, which responds with the IP address of the authoritative DNS server for the domain name. Then the authoritative DNS server responds with the IP address of the web server hosting the website.
What causes the “DNS server not responding” error?
There are several reasons that can trigger the “DNS server is not responding” error message. Here are some frequent reasons that can cause this problem:
Inappropriate DNS settings: If the DNS settings on your device are insufficient, it will not be able to establish a connection with the DNS server. This can happen if you have previously changed DNS settings, or if an automatic software update has changed it.
Router or Modem Problems: The router or modem may have difficulty connecting to the Internet. A faulty or misconfigured router/modem may cause your device to fail to establish a network connection.
Presence of malware or viruses: Malware or viruses interfering with your device’s internet connection cannot be overemphasized. These dangerous agents can change your DNS settings, limit your access to certain websites, or trigger other network-related anomalies.
Problems with DNS servers: DNS servers can be susceptible to problems that can lead to unresponsiveness to your device’s requests. This can happen if the DNS server is down, or if it is experiencing a high volume of requests that can overwhelm its processing capacity.
Troubleshooting DNS Server Not Responding Error
If you encounter the DNS server not responding error, there are several troubleshooting steps you can take to resolve the problem. Here’s a step-by-step guide to troubleshooting the error:
Checking Internet connection and network settings
The first step in troubleshooting a DNS server not responding to errors is to check your Internet connection and network settings. Make sure both your modem and router are connected to the Internet and all cables are securely plugged in.
You should also check your network settings to make sure your computer is configured to automatically obtain an IP address and DNS server address. To do this, go to your network settings and select the option to automatically obtain an IP address and DNS server address.
Flushing DNS cache
If both your Internet connection and network settings are working correctly, the next step is to flush your DNS cache. The DNS cache is a temporary storage area in which your computer stores DNS information to speed up future requests. Sometimes, the DNS cache can become corrupted, causing the DNS server to not respond to errors.
Follow these steps:
- Open command prompt as administrator. To perform this task, you need to right-click on the Command Prompt icon and then choose the “Run as administrator” option.
- You can execute the command by typing “ipconfig /flushdns” and then pressing enter key.
- Wait for the confirmation message saying “Successfully flushed DNS resolver cache”.
- Please 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 may be experiencing a DNS server outage.
To change your DNS server settings, follow these steps:
- Navigate to your network settings and choose the option to set your DNS server address manually.
- Enter a public DNS server IP address such as Google DNS (8.8.8.8) or OpenDNS (208.67.222.222).
- 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 temporarily disable your firewall or antivirus software. Your firewall or antivirus software may block access to the DNS server, causing the error to occur.
Follow these steps to disable your firewall or antivirus software:
- Open your firewall or antivirus software and locate the Temporarily Disable option
- Temporarily disable the software and try accessing the website again.
- After the website loads successfully, you may need to reconfigure your firewall or antivirus software to allow access to the DNS server. Consult your software documentation for instructions on how to do this.
Resetting the TCP/IP stack
Resetting the TCP/IP stack can also help resolve DNS server not responding errors. The TCP/IP stack refers to a group of protocols that control the way data is sent and received across the Internet. Sometimes, the TCP/IP stack can become corrupted, causing Internet connectivity problems.
To reset TCP/IP stack, follow these steps:
- Open command prompt as administrator.
- Writet he command “netsh int ip reset” and press enter.
- Wait for the confirmation message saying “Successfully reset TCP/IP stack”.
- Restart your computer & try accessing the website again.
Updating the network adapter driver
Outdated or corrupt network adapter drivers can also cause the Domain Name System server not responding error. Network adapter drivers are software programs that allow your computer to communicate with network adapter hardware.
To update your network adapter driver, follow below steps:
- Go to your computer manufacturer’s website and locate the support page.
- Enter your computer model number & select the appropriate operating system.
- Download the latest network adapter driver and save it to your computer.
- Open Device Manager and locate your network adapter.
- Right-click on the network adapter and select “Update Driver”.
- Select the option to browse your computer for driver software.
- Locate and select the downloaded network adapter drivers and follow the prompts to install them.
