When the DNS computer server does not respond, it may be caused by a variety of reasons. The following are some possible causes and corresponding solutions:

1. Network connection problem: First confirm whether the network connection is normal. If the computer cannot connect to the Internet, then the DNS server will naturally not respond. In this case, you can try restarting the computer or router, or check the network settings to ensure that the network connection is normal.

2. DNS server failure: If the network connection is normal but the DNS server still cannot respond, then the DNS server itself may be faulty. In this case, you can try contacting the network administrator or service provider to determine the status of the DNS server.

3. DNS configuration issues: Sometimes, the DNS server configuration may be incorrect, resulting in the inability to correctly resolve the domain name. In this case, you can try to check the configuration file of the DNS server to ensure that it correctly configures the mapping relationship between domain names and IP addresses.

4. DNS cache problem: Sometimes, DNS cache may cause the server to fail to respond. In this case, you can try clearing the DNS cache, or wait for a while and try to access the website again.

5. DNS security issues: If the DNS server is attacked or tampered with, it may result in an inability to respond. In this case, you can try to protect the DNS server with a security tool such as a firewall, or contact the service provider for assistance.

6. Update the operating system and drivers: Ensure that the operating system and related drivers are the latest versions. Sometimes, older versions of operating systems or drivers may be incompatible with the DNS server, causing unresponsiveness.

7. Use a public DNS server: Try to use a public DNS server, such as Google's 8.8.8.8 or Cloudflare's 1.1.1.1. These public DNS servers typically have higher resolution speeds and less failure rates.

8. Restart routers and switches: Sometimes, routers or switches may malfunction, causing the DNS server to fail to respond normally. Try restarting the router and switch to see if the problem is resolved.

9. Check the firewall settings: Make sure the firewall does not block access to the DNS server. Sometimes, firewalls may misjudge DNS servers as malware, causing them to not work properly.

10. Contact the service provider: If none of the above methods can solve the problem, you can try to contact the Internet service provider or DNS service provider to report the problem to them and ask for help. They may offer a more professional solution.

In short, when the DNS computer server does not respond, you can solve the problem from many aspects. In addition to the methods mentioned above, you can also try updating the operating system and drivers, using public DNS servers, restarting routers and switches, checking firewall settings, and contacting service providers. Hope these methods can help you solve the problem.

In short, when the DNS computer server does not respond, you need to solve the problem from multiple aspects. First confirm whether the network connection is normal, then check the status and configuration of the DNS server, and finally consider clearing the DNS cache or using security tools to protect the DNS server. If the problem persists, you can contact your service provider or network administrator for assistance.
