What Does “DNS Server Not Responding” Mean?

The DNS (Domain Name System) server is a critical component of the internet that translates domain names (like www.google.com) into IP addresses that computers understand. When your device cannot communicate with the DNS server, your browser displays the error message, “The DNS server is not responding.” This essentially means your system is unable to resolve the website's address.

Common Causes of the Error

Before diving into solutions, it’s essential to understand what might be causing the issue. Here are some common reasons:

  1. Network Configuration Issues: Misconfigured network settings on your device can cause DNS errors.
  2. Faulty DNS Server: The DNS server provided by your Internet Service Provider (ISP) might be experiencing downtime.
  3. Outdated Drivers: An outdated or corrupted network adapter driver can lead to connectivity problems.
  4. Firewall or Antivirus Software: Overly strict security software may block access to the DNS server.
  5. Router Issues: Problems with your router or modem can interrupt the connection.
  6. Cache Problems: A corrupted DNS cache can prevent successful domain resolution.
  7. ISP Restrictions: Sometimes, your ISP may block certain DNS servers or websites.

How to Fix “The DNS Server is Not Responding” Error

Now that we know the possible reasons, let's look at the possible solutions to fix the "DNS Server Not Responding" problem. You don't have to try them all - just work until the problem is solved.

1. Restart Your Computer and Router

The first and simplest solution is to restart your computer and router. This can resolve temporary glitches in your network connection.

Steps to Restart:

  • Turn off your computer.
  • Power off your router or modem and unplug it.
  • Wait for about 30 seconds.
  • Plug in and turn on the router, then start your computer.

2. Switch to a Different Browser

Sometimes, the DNS server not responding issue may be specific to your browser. Try accessing the website using another browser (e.g., switch from Chrome to Firefox or Edge). If the problem persists, proceed to the next step.

3. Disable Your Firewall and Antivirus Temporarily

Overprotective firewall or antivirus software can block DNS servers. Temporarily disable them to check if they are causing the issue.

Steps to Disable Firewall (Windows):

  • Open the Control Panel.
  • Go to System and Security > Windows Defender Firewall.
It is showing that a window (Control Panel) is open then you need to click on Windows Defender Firewall
  • Click on Turn Windows Defender Firewall on or off.
  • Select Turn off Windows Defender Firewall for both private and public networks.

If this resolves the DNS server not responding issue, consider resetting your firewall settings instead of disabling it.

4. Flush Your DNS Cache

Flushing the DNS cache clears any corrupted entries that may be causing the error.

Steps to Flush DNS (Windows):

  1. Press Win + R, type cmd, and press Enter.
  2. In the Command Prompt, type the following command and press Enter:
  3. ipconfig /flushdns
  4. You should see a message confirming the DNS cache has been successfully flushed.

5. Change Your DNS Server

If the default DNS server from your ISP is unreliable, you can switch to a public DNS server like Google DNS or Cloudflare DNS.

Steps to Change DNS Server (Windows):

  • Open the Control Panel and go to Network and Internet > Network and Sharing Center.
  • Click on your active connection (e.g., Ethernet or Wi-Fi).
  • Click Properties and double-click on Internet Protocol Version 4 (TCP/IPv4).
A new window will open Wi-Fi Status Now you need to click on Properties which is below. Then a new window Wi-Fi Properties will open.

  • Select Use the following DNS server addresses and enter:

Preferred DNS server: 8.8.8.8 (Google DNS)
Alternate DNS server: 8.8.4.4 (Google DNS)
  • Click OK to save changes.

6. Update Your Network Adapter Driver

Outdated or corrupted drivers can cause connectivity issues.

Steps to Update Drivers (Windows):

  1. Press Win + X and select Device Manager.
  2. Expand Network adapters.
  3. Right-click on your network adapter and choose Update driver.
  4. Select Search automatically for drivers and follow the on-screen instructions.

7. Perform a Network Reset

Resetting your network settings can resolve misconfigurations.

Steps to Reset Network (Windows):

  1. Open Settings and go to Network & Internet > Status.
  2. Scroll down and click Network reset.
  3. Confirm by clicking Reset now.
  4. Restart your computer after the reset.

8. Test Your Internet Connection on Another Device

To determine if the problem is with your device or the network, try accessing the internet on another device (e.g., a smartphone connected to the same Wi-Fi). If the other device works fine, the issue is specific to your computer.

9. Contact Your Internet Service Provider (ISP)

If none of the above solutions work, the problem might be with your ISP. Reach out to them to inquire about DNS server issues or restrictions.

10. Use a Different Network

As a last resort, try connecting to a different Wi-Fi network or use a mobile hotspot to see if the issue persists.

Preventing DNS Issues in the Future

Here are some tips to minimize the chances of encountering DNS errors in the future:

  1. Use Reliable DNS Servers: Switch to trusted public DNS servers like Google DNS or Cloudflare DNS.
  2. Keep Your System Updated: Regularly update your operating system, drivers, and browser.
  3. Avoid Overloading Your Network: Ensure your network isn't bogged down with excessive devices or downloads.
  4. Regularly Restart Your Router: Periodically restarting your router can help maintain its performance.
  5. Monitor Security Software: Ensure that your antivirus and firewall settings don’t interfere with your network connection.
