Why my server resolve DNS error？

Question

The operating system version is Windows Server 2016 Standard Edition, and an error occurred while resolving the domain name. For example, www.baidu.com resolved an IP address of 127.88.0.1. Therefore, the domain name was set to IP 1.1.1.1 in the hosts file, but still resolved to 127.88.0.1.

May I ask why such a problem has arisen and how it should be resolved?

Hello 延龙 孙,

Thank you for posting in Q&A forum.

 For a quick check, please check the settings below:

1. Check DNS settings on client.
2. Flush DNS cache: using the ipconfig /flushdns command on both server and client.
3. Check Host file.
4. Check DNS server and forwarder configuration.
5. Use Nslookup to troubleshoot DNS resolve process.

And I really recommend you follow this troubleshooting link, once you finished, you will understand how DNS works:
