One of the most irritating errors is that of a "DNS server not responding"; it just literally cuts off your way to the internet. DNS, or the Domain Name System, is responsible for translating such domain names as example.com into IP addresses used by computers to talk with one another. When it goes down, you can't access any websites or online services. Now let's try to take a closer look at some of the common causes and practical solutions which could work on this problem.

What Does the Error Mean?

Well, whenever you see "DNS server not responding," it only implies that your computer is not communicating with the DNS server used for resolving domain names. The reasons can be anything-from server issues to incorrect settings to problems related to network connectivity.

Common Causes of the Error

  1. Incorrect Network Configuration
    If the DNS settings or network properties are set up incorrectly, it may prevent proper communication with the DNS server.

  2. DNS Server of your ISP
    Sometimes, the DNS server of your ISP is down or overloaded.

  3. Firewall or Antivirus blocking DNS
    Sometimes, one of your security applications has wrongly blocked DNS traffic, and that leads to the error.

  4. Outdated Network Drivers
    In addition, the use of very old or incompatible drivers will crash network functionality and can cause DNS errors.

  5. Hardware Problems
    These are problematic routers, modems, and network cables interfering with DNS communication.

How to Fix DNS Server Not Responding Errors

Following are the actual steps toward troubleshooting and solution of this problem:

  1. Reboot Your Devices
    Reboot your computer, router, and modem. This will refresh the transient glitches and often solves small problems.

  2. Check Your Internet Connection
    Ensure your internet connection is fine. Try it on other devices on the same network.

  3. Change Your DNS Server
    Change your DNS server to some public DNS services such as:

    • Google DNS: 8.8.8.8 and 8.8.4.4
    • Cloudflare DNS: 1.1.1.1 and 1.0.0.1
      Renewing these settings can get around issues with your ISP's DNS server.
  4. Flush DNS Cache
    This will clear corrupted DNS entries. Please run the following command inside your terminal:

    ipconfig /flushdns
  1. Temporarily Turn Off Firewall or Antivirus Software
    Sometimes security software will block DNS traffic. Briefly disable them just to rule them out as causes. Remember, don't forget to turn this back on later.

  2. Update Network Drivers
    Outdated drivers could also be a cause of connectivity issues. Update your network adapter driver through your device manager or download the latest version from the manufacturer's website.

  3. Try Another Device or Network
    Isolate whether the issue is just to one device. If other devices work fine, then the problem may be with your computer.

  4. Reset Your Router
    Reset your router to its default settings. Consult your router's manual for instructions, as this will erase any custom configurations.

  5. Use Safe Mode
    Boot your computer into safe mode with networking. If the issue is resolved, it could indicate software interference in normal mode.

  6. Contact Your ISP
    If all else fails, your ISP might be experiencing DNS server issues. Contact their support team for assistance.

Preventing Future Issues

  • Keep updating your devices and drivers regularly.
  • Use public DNS services of a reliable service provider.
  • Set the correct network security settings.
  • Hardware wear or failure in the network should be checked.

Conclusion

DNS Server errors sound huge, but actually most of these are quite simple to resolve through a step-by-step methodology. These steps should help to identify the cause and reconnect to the Internet.

If the problem persists, then it is time to consult professionals or upgrade your networking equipment. Stay connected-keep your DNS updated and check up on your network every so often.
