When encountering the problem of "DNS server not responding", it is usually because the computer cannot access the website through domain name resolution. Solutions include: 1. Check whether the basic network connection is normal, confirm the router's running status and whether other devices can access the Internet; 2. Change or reset the DNS server address, and manually specify public DNS such as Google's 8.8.8.8 and 8.8.4.4; 3. Reset network settings and services, and execute commands such as netsh winsock reset, netsh int ip reset, ipconfig /release, ipconfig /renew and ipconfig /flushdns; 4. Ensure that the "DNS Client" system service has been started and set to automatic; 5. Update the network card driver and check whether the firewall or antivirus software interferes with DNS requests.

When encountering the problem of "DNS server not responding", it usually means that your computer cannot access the website through domain name resolution. Although it may be connected to the network, the web page cannot be opened. The solution is actually not too complicated, and it mainly focuses on network settings, DNS configuration and system services.

Check whether the basic network connection is normal

First, confirm whether it is a problem with the network itself. for example:

• Is the router running normally? Can other devices be accessed online?
• If it is a Wi-Fi connection, try switching to a wired connection to see if there is any improvement.
• Restart the router and modem, sometimes a simple restart can solve the problem.

If other devices are fine and only your Windows computer has an error, you can basically confirm that the problem lies in the local configuration.

Replace or reset the DNS server address

By default, most Windows systems will automatically obtain DNS addresses, but sometimes the operator's DNS server is unstable or blocked, which will lead to resolution failure. It will be helpful to manually specify a public DNS at this time.

You can try the following:

1. Open Control Panel → Network and Sharing Center → Click the name of the currently connected network.
2. Click "Properties" → Double-click "Internet Protocol Version 4 (TCP/IPv4)".
3. Select "Use the following DNS server address":
   • Preferred DNS server: 8.8.8.8
   • Alternate DNS server: 8.8.4.4 (This is the public DNS provided by Google)

After saving, try opening the browser again. If you don't want to use Google's DNS, you can also change it to Cloudflare's 1.1.1.1 or OpenDNS address.

Reset network settings and services

Sometimes, problems with the system's own network protocol or service can also lead to DNS exceptions. You can try the following commands:

• Open a command prompt (run as administrator):
  • Enter netsh winsock reset to enter
  • Enter netsh int ip reset reset
  • Enter ipconfig /release and ipconfig /renew to refresh the IP
  • Finally, execute ipconfig /flushdns to clear the cache

These commands can fix some common network protocol errors and DNS caching issues. After completion, it is recommended to restart the computer to see the effect.

In addition, check whether the DNS Client system service is enabled:

1. Press Win R and enter services.msc to enter
2. Find the "DNS Client" service and right-click to view the properties
3. Make sure the startup type is "automatic" and the current status is "running"

If not, click the "Start" button to make it run.

Troubleshooting driver and firewall interference

Sometimes the network card driver is too old or damaged, which can also affect the DNS response. You can update the network card driver in the device manager, especially the related devices under the "Network Adapter".

In addition, some antivirus software or firewalls may intercept DNS requests. You can try temporarily closing third-party security software to see if the problem is alleviated.

Basically these common ways of handling it. In most cases, changing DNS first and then resetting the network service can solve the problem of "DNS server not responding". If you accidentally correct the wrong settings, remember to restore to "Automatically obtain DNS server address".
