Fix DNS Server Not Responding – Resolve Common Issues

Dealing with DNS server issues can be frustrating. In this article, we will discuss common problems and how to resolve them.

Check your internet connection to ensure it is stable and functioning properly.

Understanding “DNS Server Not Responding” Errors

When encountering a “DNS Server Not Responding” error, it is important to first determine the cause of the issue. Start by checking the network connection and ensuring that the DNS server settings are configured correctly.

If the problem persists, try flushing the DNS cache to clear any outdated information that may be causing the error. This can be done by opening the Command Prompt and entering the command “ipconfig /flushdns”.

Another common solution is to change the DNS server to a public DNS server such as Google’s DNS ( and or OpenDNS. This can be done by accessing the network adapter settings and entering the new DNS server address.

It is also important to check for any firewall or antivirus software that may be blocking the DNS server connection. Temporarily disabling these programs can help identify if they are the cause of the error.

If the issue persists, consider restarting the router or modem to reset the network connection.

Recognizing Signs of DNS Trouble

Another sign to watch for is slow or inconsistent website loading times, especially for sites you visit frequently. If you notice that some websites take longer to load than others, it could be a sign that your DNS server is struggling to resolve the domain names.

Additionally, error messages such as “server not found” or “DNS server could not be reached” are clear indicators of DNS trouble. These messages often appear when your computer is unable to connect to the correct DNS server to resolve a domain name.

By recognizing these signs of DNS trouble, you can take the necessary steps to resolve common issues and improve your internet connection.

Troubleshooting Network and ISP Issues

Another common issue is incorrect DNS settings. To fix this, reset your DNS settings to default or try using a different DNS server such as Google’s public DNS.

If you’re still experiencing issues, check for any firewall or antivirus software that may be blocking your connection and temporarily disable them to see if it resolves the problem.

It’s also worth clearing your browser’s cache and cookies as these can sometimes cause DNS issues. Additionally, run a ping test to check if your connection to the DNS server is working properly.

In some cases, the issue may be related to Winsock corruption or network adapter problems. You can reset your Winsock catalog or update your network adapter drivers to resolve these issues.

To fix DNS server not responding issues, a simple restart of your networking equipment and computer can often resolve the problem. First, unplug your modem and router from the power source. Wait for about 30 seconds, then plug them back in and wait for them to fully reboot.

Next, restart your computer to ensure that it establishes a fresh connection to the network. After restarting, try accessing the websites that were previously giving you DNS errors.

If the issue persists, you may need to troubleshoot further by checking your network settings or contacting your ISP for assistance. Remember to update your antivirus software and check for any firewall settings that could be blocking your connection.

By restarting your networking equipment and computer, you can often quickly resolve DNS server not responding issues and get back online without any further hassle.

Flush DNS Cache and Reset Network Protocols

  1. Open Command Prompt by typing “cmd” in the search bar and selecting it from the list of results.
  2. Type ipconfig /flushdns and press Enter.
  3. Wait for the confirmation message that the DNS cache has been successfully flushed.

Reset Network Protocols

  1. Open Command Prompt by typing “cmd” in the search bar and selecting it from the list of results.
  2. Type netsh winsock reset and press Enter.
  3. Restart your computer to apply the changes to the network protocols.

Perform a Clean System Reboot

In the Command Prompt window, type “ipconfig /flushdns” and press Enter to clear the DNS cache. Next, type “ipconfig /release” and press Enter to release the current IP address, followed by “ipconfig /renew” and press Enter to obtain a new IP address from the router.

After completing these steps, restart your computer once again to ensure that the changes take effect. This clean system reboot can help resolve common DNS server not responding issues and improve your internet connectivity.

Update and Reinstall Network Adapter Driver

To update and reinstall your network adapter driver, first press the Windows key + X on your keyboard. This will open the context menu. Click on “Device Manager” from the list of options that appear. In the Device Manager window, locate and expand the “Network adapters” section. Right-click on your network adapter and select “Update driver.” Follow the on-screen instructions to complete the update process.

If updating the driver does not resolve the issue, you can try reinstalling the network adapter driver. To do this, go back to the Device Manager, right-click on your network adapter, and select “Uninstall device.” Once the driver is uninstalled, restart your computer. Upon restarting, Windows will automatically reinstall the network adapter driver.

This should resolve any DNS server not responding issues related to your network adapter driver.

Configure to Public DNS Servers

1. Right-click on the network icon in the notification area and select Open Network and Sharing Center.

2. Click on your active network connection, then click Properties.

3. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

4. Select Use the following DNS server addresses and enter the preferred and alternate DNS server addresses provided by your chosen public DNS service.

5. Click OK to save the changes.

6. To verify the changes, open a command prompt and type ipconfig /flushdns to clear the DNS cache.

7. Finally, open a web browser and test whether the DNS server not responding issue has been resolved.

By configuring to public DNS servers, you can potentially resolve common DNS server issues and improve your internet browsing experience.

Disable Unnecessary Network Connections

Additionally, you can also disable IPv6 from your network adapter settings, as this can sometimes cause conflicts with DNS resolution. Right-click on your network adapter and select Properties, then uncheck the box next to Internet Protocol Version 6 (TCP/IPv6). This will help to prioritize IPv4 for DNS resolution and potentially resolve the server not responding issue.

By disabling unnecessary network connections and IPv6, you can streamline your network setup and potentially resolve common DNS server issues. Keep in mind that these steps are specific to Windows 10, but similar actions can be taken on other operating systems to achieve similar results.

Temporarily Turn Off Antivirus and Firewall Software

To fix DNS server not responding issues, you may need to temporarily turn off your antivirus and firewall software. Sometimes, these programs can block the connection to the DNS server, causing the problem.

First, locate your antivirus software icon in the system tray or in the start menu. Right-click on the icon and look for an option to disable or turn off the program.

Next, you will need to do the same for your firewall software. Find the firewall icon in the system tray or in the control panel. Look for an option to disable the firewall temporarily.

Once both antivirus and firewall software are turned off, try accessing the website or web page again to see if the DNS server issue has been resolved.

Check and Adjust Power Settings

If you’re using a desktop, ensure that the network adapter’s power saving mode is turned off. To do this, go to Device Manager, locate your network adapter, right-click on it, and select “Properties.” Then go to the “Power Management” tab and uncheck the box that says “Allow the computer to turn off this device to save power.”

Next, reset your TCP/IP settings by opening Command Prompt as an administrator and typing the following commands:
– “netsh winsock reset”
– “netsh int ip reset
– “ipconfig /release”
– “ipconfig /renew”

After doing this, restart your computer and check if the DNS server not responding issue has been resolved. If not, consider resetting your router or contacting your Internet Service Provider for further assistance.
