If you encounter the "DNS Server Not Responsive" issue, you can resolve it by changing your DNS settings. The specific method is to manually replace it with a more stable public DNS, such as Google 8.8.8.8 or Cloudflare 1.1.1.1 to replace the default automatically acquired ISP DNS.

When encountering the problem of "DNS server not responding", many people's first reaction may be to restart the router or computer. In fact, this problem is quite common on Windows. In most cases, it is not a big problem, but it does affect the Internet experience. The solution is not complicated, mainly checking network settings and system configuration.

Check basic connections and hardware

Many times, the problem of "DNS server not responding" is not a problem with DNS itself, but a result of unstable network connections or device failures. You can try the following steps first:

• Confirm whether the network cable is plugged in properly. If it is a wireless connection, check whether the Wi-Fi is connected normally.
• Restart the router and modem, sometimes the device will run for a long time and may cause some temporary failures.
• If you are using public Wi-Fi or corporate network, it may be that the network administrator has restricted it. Try changing to another network.

Although these steps seem simple, they can often eliminate many problems. If it still doesn't work after it is done, then you have to start with the system and settings.

Change DNS settings

Windows will automatically obtain the DNS address by default, but if there is a problem with the DNS provided by the ISP, it will cause the Internet to be unable to access. Manually changing to a more stable public DNS is a good choice at this time.

Common alternatives are:

• Google Public DNS: 8.8.8.8 and 8.8.4.4
• Cloudflare DNS: 1.1.1.1
• Alibaba Cloud DNS: 223.5.5.5

The operation method is also very simple:

1. Open Control Panel → Network and Internet → Network and Sharing Center
2. Click the currently connected network → select "Properties"
3. Double-click "Internet Protocol Version 4 (TCP/IPv4)"
4. Select "Use the following DNS server address"
5. Fill in the DNS address you selected and save it

This method is suitable for most home users, if you are not sure which one to use, Google's 8.8.8.8 is a safe choice.

Clear DNS cache and reset network settings

Sometimes errors in locally cached DNS records can also cause problems. You can clear the cache through the command prompt:

 ipconfig /flushdns

If it doesn't work, you can also try resetting TCP/IP and Winsock:

 netsh int ip reset
netsh winsock reset

After executing these commands, you need to restart the computer and take effect. This method is suitable for people who are not very familiar with the command line but are willing to do it. It is not complicated to operate, but you should pay attention to the order that cannot be reversed.

In addition, some security software (such as firewalls, antivirus software) may also interfere with DNS requests. You can try to close them temporarily to see if the problem is resolved.

Basically these are the methods. In most cases, you can do it by changing DNS or clearing the cache. If none of them works, it may be a problem with the Internet service provider, and they will be fine after they are fixed.
