How To Fix DNS Server Not Responding on Windows 11

A practical approach to resolving DNS server errors on Windows 11

23views

When the DNS server is not responding, it indicates that your PC cannot find the IP address of the website that you are attempting to visit. This issue usually results in an error message. A DNS server is responsible for translating domain names into IP addresses, so it’s a crucial component of your internet connection.

There are several reasons why a DNS server may not respond, such as when it’s down or overloaded, the router is misconfigured, the DNS settings are incorrect, or your internet connection is interrupted. If you’re experiencing this problem, you may notice that you’re unable to open websites and see an error message, some websites can open but not others, or your internet speed is slow.

1. Use a different web browser

If your DNS server is not responding while accessing a website, you can try a different web browser. This may be a potential solution. For instance, if your current browser is Microsoft Edge or Mozilla Firefox, try accessing the website using Google Chrome or another browser.

If a different browser solves the issue, you can make it your default browser. However, if the problem persists, it is clear that your previous browser is not the cause of the issue. In this case, you should continue investigating other solutions to fix the problem.

2. Use a different device

If you encounter an error while trying to access a website after using a different browser on that computer, attempting to access the website using another device connected to your home network may be a good idea.

For instance, you can use Wi-Fi from your mobile phone to access the relevant website. If the error persists even after trying to access it from another device, the issue might not be with your primary device alone. In such a situation, the problem may have something to do with your router.

3. Restart Your Router

The DNS Server not responding issue may occur due to high data traffic. Simply restarting your router can often fix this issue. To restart your router, press the power button on the device and then unplug its power cable. Wait about 30 seconds, and then plug the power cable back in. Finally, press the power button to restart the router.

4. Run the Network Adapter troubleshooter

Running the Network Adapter troubleshooter is a reliable fix that automatically detects and resolves common network adapter issues. The troubleshooter scans for network adapter settings problems relating to IP configuration and connectivity and attempts to fix them. Here is how to do it.

  1. Press the Windows and I keys together to open the Settings menu.
    0x80d03801
  2. Then, open the System option.
  3. Now scroll down to find the Troubleshoot option and click to enter, then click on Other trouble-shooters.

6. Clear DNS cache

Clearing the DNS cache means removing stored domain name records from your computer’s temporary storage. When you visit a website, your computer checks the DNS cache for its IP address. If not found, your computer queries a DNS server. Once obtained, your computer stores the IP address in the DNS cache to avoid querying the server again.

Use the Command Prompt to flush the DNS cache on your computer. To complete this task, here are the steps:

  1. Hold the Windows + S keys simultaneously, enter the command keyword in the search field while holding the CTRL and Shift keys down, and hit ENTER to start the Command Prompt as an admin.
    CheckNetIsolation.exe
  2. When you receive a prompt, click Yes.

  3. Once the Command Prompt opens, enter the following command and hit Enter:
    ipconfig /flushdns
    flush dns cache on windows
  4. Finally, restart your PC.

7. Change Your DNS

In case of any issues with DNS servers, changing the DNS can help resolve the problem. Different DNS can improve internet speed and reliability and prevent errors during updates. To change DNS in Windows 11, follow these steps:

  1. Press the Windows + S keys simultaneously to open the search bar, type network connections, and click View network connections.
    Windows 11 Update Error 0x8024402f
  2. Then, right-click on your desired adapter and click Properties.
    DHCP Error 0x79
  3. Then, click on Internet Protocol Version 4 (TCP/IPv4) and click on the Properties button.
  4. When the new window opens, choose Use the following DNS server addresses: from the second section and set the following:
    Preferred DNS server: 8.8.8.8
    Alternate DNS server: 8.8.4.4
    Windows 11 Update Error 0x8024402f
  5. Finally, click on OK and try restarting your PC.

8. Update the Wireless Network Adapter

Updating the Network driver will install the latest updates and security patches. A wireless network adapter allows your computer to connect to a wireless network by converting the router’s radio signals into electrical signals that your computer can understand. With this, no cable is required.

Follow the steps below to complete the installation.

  1. Press Windows + X to open the Quick Link menu, then choose Device Manager.
  2. Then, expand Network adapters.
  3. Right-click your wireless network adapter and click Update driver

  4. Once the next screen opens, choose the Search automatically for drivers option.
  5. Wait for the process to complete.
  6. Finally, restart your PC.

9. Boot the PC in Safe Mode

Booting your PC in Safe Mode and checking Event Viewer can help troubleshoot and fix kernel-mode heap corruption. Safe Mode starts only basic drivers and services needed to run the system, helping to eliminate potential software conflicts. Event Viewer logs events related to kernel mode heap corruption.

Follow the steps below to complete the task:

  1. Press the Windows + S keys to access the search box, enter Recovery options, and click on the correct app to open.
    exit safe mode windows 11
  2. Then, find Advanced startup and select Restart now.
  3. When the next window opens, choose Troubleshoot.

  4. Then click on Advanced options.
    eax dll
  5. Afterward, select the Startup setting.
  6. Finally, choose the following option:
    • F5 – Enable Safe Mode with Networking
      Error code 0x8024000c

In conclusion, encountering a DNS Server Not Responding error on Windows 11 can be frustrating, but effective strategies to overcome it exist. This guide provides insights on resetting DNS configurations, checking network hardware, and exploring alternative DNS servers.

Remember to be patient and thorough as you implement these fixes. May your online experiences be uninterrupted and your connectivity remains steadfast.
