How to Fix DNS Activation Problems Not Working on Windows 11: Step-by-Step Solutions

DNS activation problems on Windows 11 can prevent you from accessing websites or online services properly. This issue often occurs due to network configuration errors or system glitches. Fortunately, fixing DNS problems is usually straightforward with a few simple steps.

In this guide, we will walk you through easy and effective methods to resolve DNS activation issues on your Windows 11 computer. Each step is explained in detail, so even beginners can follow along.

By the end of this article, you should be able to restore normal DNS functioning and browse the internet without interruptions. Let’s get started with some quick checks before diving into troubleshooting.

These solutions require no advanced technical skills and can be performed using built-in Windows tools.

Quick Note: Basic Checks Before Troubleshooting

  • Ensure your internet connection is active: Check if other devices on the same network can access the internet.
  • Restart your router and PC: Sometimes, a simple reboot can fix temporary network issues.
  • Verify network cables and Wi-Fi: Make sure your PC is properly connected to the network.
  • Check for Windows updates: Keeping your system updated can resolve known bugs affecting DNS.

Step 1: Flush DNS Cache

Sometimes, outdated or corrupted DNS cache can cause activation problems. Flushing the DNS cache clears old records and forces Windows to retrieve fresh DNS data.

  1. Press Windows + S and type Command Prompt.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the command window, type the following command and press Enter:
ipconfig /flushdns

You should see a confirmation message saying the DNS Resolver Cache was successfully flushed. Close the window and check if your DNS issues are resolved.

Step 2: Restart DNS Client Service

The DNS Client service manages DNS requests on your PC. Restarting it can fix glitches affecting DNS activation.

  1. Press Windows + R to open the Run dialog.
  2. Type services.msc and press Enter.
  3. In the Services window, scroll down and find DNS Client.
  4. Right-click on DNS Client and select Restart.
  5. Wait a few seconds for the service to restart, then close the window.

After restarting the service, test your internet connection again.

Step 3: Change DNS Server Addresses

Your DNS problems may be caused by issues with your current DNS servers. Switching to a reliable public DNS, such as Google DNS or Cloudflare, can help.

  1. Press Windows + I to open Settings.
  2. Navigate to Network & Internet > Advanced network settings > More network adapter options.
  3. Right-click your active network connection and select Properties.
  4. Scroll and select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
  5. Select Use the following DNS server addresses.
  6. Enter the following DNS addresses:
  • Preferred DNS server: 8.8.8.8 (Google DNS)
  • Alternate DNS server: 8.8.4.4 (Google DNS)

Alternatively, you can use Cloudflare DNS:

  • Preferred DNS server: 1.1.1.1
  • Alternate DNS server: 1.0.0.1
  1. Click OK to save changes and close all windows.

Try accessing the internet again to see if DNS activation problems are fixed.

Step 4: Reset Network Settings

If the above steps don’t help, resetting your network settings can restore default configurations and fix DNS errors.

  1. Open Settings by pressing Windows + I.
  2. Go to Network & Internet.
  3. Scroll down and click Advanced network settings.
  4. Under More settings, click Network reset.
  5. Click the Reset now button and confirm.
  6. Your PC will restart automatically to complete the reset process.

After reboot, check if your DNS issues are resolved. Note that this will remove and reinstall all network adapters and reset settings to default.

Step 5: Run the Network Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and fix common network problems automatically.

  1. Open Settings (Windows + I).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Internet Connections and click Run.
  4. Follow on-screen instructions to let Windows diagnose and fix issues.

This tool can identify DNS-related problems and attempt automatic repairs.

Alternative Methods and Advanced Options

If you are comfortable with more advanced steps, consider the following options:

  • Update Network Adapter Drivers: Outdated drivers can cause DNS issues. Use Device Manager to check for updates.
  • Check Hosts File: Sometimes, entries in the hosts file can block DNS resolution. You can edit this file located at C:WindowsSystem32driversetchosts using Notepad (run as administrator).
  • Disable VPN or Proxy: VPNs or proxies may interfere with DNS activation. Temporarily disable them to test connectivity.

Frequently Asked Questions (FAQs)

What is DNS and why is it important?

DNS (Domain Name System) translates website names into IP addresses, allowing your computer to find and connect to websites. Without DNS working properly, you cannot access websites using domain names.

Why does flushing DNS cache help resolve problems?

Flushing DNS cache removes stored information that may be outdated or corrupted. This forces your computer to request fresh DNS data from servers, fixing potential lookup errors.

Can changing DNS servers improve internet speed?

Sometimes, yes. Using faster or more reliable DNS servers like Google DNS or Cloudflare can reduce the time it takes to resolve domain names, improving browsing speed.

Will resetting network settings delete my Wi-Fi passwords?

Yes, resetting network settings removes saved Wi-Fi networks and passwords. You will need to reconnect to Wi-Fi and enter passwords again.

Is it safe to use public DNS servers?

Yes, popular public DNS servers like Google and Cloudflare are widely used and considered safe. They often provide better performance and security than some ISP DNS servers.

When Nothing Works

If you have tried all the steps above and still experience DNS activation problems, consider these final options:

  • Contact your Internet Service Provider (ISP): The issue might be on their end or related to your account.
  • Run System File Checker (SFC): Corrupted system files can affect networking. Open Command Prompt as administrator and run sfc /scannow.
  • Seek help from Microsoft Support: Visit the official Microsoft Support website for advanced assistance.
  • Consider a system restore: If DNS problems started recently, restoring Windows to an earlier point may fix the issue.

Conclusion

DNS activation problems on Windows 11 are common but usually easy to fix. Starting with basic steps like flushing the DNS cache and restarting services often solves the issue. Changing DNS servers and resetting network settings can help if the problem persists.

Remember to perform simple checks before troubleshooting, and use built-in Windows tools like the Network Troubleshooter to automate fixes. If all else fails, don’t hesitate to contact your ISP or Microsoft Support for further help.

Following this guide will help you regain a stable and functional internet connection quickly and without hassle.
