How to Fix DNS Server Not Responding Error on Windows 8.1: Step-by-Step Solutions

Experiencing a “DNS Server Not Responding” error on your Windows 8.1 can be frustrating. This issue prevents your computer from connecting to the internet properly, even if your network seems fine. Fortunately, there are straightforward steps you can take to resolve this problem.

This guide will walk you through easy-to-follow methods to fix the DNS error. Each step is explained clearly, so even if you are not tech-savvy, you can follow along without confusion.

Let’s begin with some quick checks to save time before moving on to more detailed troubleshooting.

By the end, you should be able to resolve the DNS server issue and get your internet working again.

Quick Note: Prerequisites and Initial Checks

Before diving into the detailed solutions, make sure you have completed these basic checks. Sometimes, the problem is simple and can be fixed quickly.

  • Check your internet connection: Ensure your modem and router are turned on and connected properly.
  • Restart your computer and router: This simple step can clear temporary glitches affecting your connection.
  • Try connecting another device: See if other devices on the same network are facing the same issue. If yes, the problem might be with your network or ISP.
  • Disable any VPN or proxy: Sometimes, VPNs or proxies interfere with DNS queries.

Step 1: Flush DNS Cache

Flushing the DNS cache removes any incorrect or outdated DNS data stored on your computer. This can often fix DNS-related errors.

  1. Press the Windows key + X on your keyboard and select Command Prompt (Admin) or Windows PowerShell (Admin).
  2. In the command window, type the following command and press Enter: 
    ipconfig /flushdns
  3. You should see a message saying, “Successfully flushed the DNS Resolver Cache.”
  4. Restart your computer and check if the internet connection works.

Why is this important? Sometimes, your computer keeps old DNS information that no longer works. Flushing clears this so your system can request fresh information.

Step 2: Change DNS Server Address Manually

Your DNS server is responsible for translating website names into IP addresses. If your current DNS server is unresponsive, manually changing it to a public DNS like Google’s or Cloudflare’s can help.

  1. Press Windows key + X and select Network Connections.
  2. Right-click on your active network (Wi-Fi or Ethernet) and select Properties.
  3. Scroll down and double-click on Internet Protocol Version 4 (TCP/IPv4).
  4. Select Use the following DNS server addresses.
  5. Enter the following DNS addresses:
    • Preferred DNS server: 8.8.8.8
    • Alternate DNS server: 8.8.4.4
  6. Click OK to save the changes, then close all windows.
  7. Restart your browser or computer and check the connection again.

Why change DNS servers? Sometimes your Internet Service Provider’s DNS servers are slow or down. Using reliable public DNS servers often resolves these issues.

Step 3: Disable and Re-enable Network Adapter

Disabling and re-enabling your network adapter can reset the connection and fix minor glitches.

  1. Open Network Connections again by pressing Windows key + X and choosing Network Connections.
  2. Find your active network adapter, right-click on it, and select Disable.
  3. Wait a few seconds, then right-click again and select Enable.
  4. Check if your internet connection is restored.

Why do this? Sometimes, network devices get stuck or have temporary faults. Restarting the adapter refreshes its status.

Step 4: Reset TCP/IP Stack

The TCP/IP stack is critical for internet communication. Resetting it can fix deeper network issues.

  1. Open Command Prompt (Admin) again (Windows key + X).
  2. Type the following commands one by one, pressing Enter after each: 
    netsh int ip reset
netsh winsock reset
  3. Restart your computer to apply the changes.
  4. Try accessing the internet again.

Why reset TCP/IP? This clears corrupt or misconfigured network settings that can cause DNS errors.

Step 5: Temporarily Disable Firewall and Antivirus

Sometimes, firewalls or antivirus programs block DNS requests mistakenly. Temporarily disabling them can help identify if they are causing the problem.

  1. Open your antivirus program or Windows Defender.
  2. Look for an option to temporarily disable protection.
  3. Disable your firewall temporarily via Control Panel > System and Security > Windows Firewall.
  4. Try reconnecting to the internet.
  5. If this fixes the problem, add exceptions for DNS or network programs in your security software.

Important: Always remember to re-enable your firewall and antivirus after testing.

Alternative Method: Use Network Troubleshooter

Windows 8.1 includes a built-in troubleshooter that can automatically detect and fix network issues including DNS problems.

  1. Open the Control Panel and go to Network and Internet > Network and Sharing Center.
  2. Click on Troubleshoot problems on the left side.
  3. Select Internet Connections and follow the on-screen instructions.
  4. If the troubleshooter finds issues, it will attempt to fix them automatically.

Frequently Asked Questions (FAQs)

What does “DNS server not responding” mean?

It means your computer is unable to communicate with the DNS server, which translates website names into IP addresses. Without this, you cannot browse the internet.

Can restarting my router fix the DNS issue?

Yes, restarting your router can clear temporary glitches or network congestion that might cause DNS errors.

Are public DNS servers safe to use?

Yes, popular public DNS servers like Google DNS (8.8.8.8) and Cloudflare DNS (1.1.1.1) are safe and often faster than ISP-provided DNS.

Will resetting TCP/IP affect my other network settings?

Resetting TCP/IP restores network settings to default, which can fix issues but may also remove custom network configurations. You might need to reconfigure VPNs or static IPs afterward.

Why does disabling antivirus help fix DNS errors?

Some antivirus or firewall software may block DNS requests by mistake. Disabling them temporarily helps identify if they are the cause.

When Nothing Works
