I am currently experiencing issues accessing one of my client’s servers, and it appears to be a problem with the network connection between my computer and the server. I attempted to troubleshoot by using the nslookup command in the Windows command line to retrieve the server’s IP address, but it did not work. Running any nslookup command returns “No response from server.” For example, when I run “nslookup www.google.com,” I get the following output:
C:\Windows\system32>nslookup www.google.com
Server: UnKnown
Address: 2606:4700:4700::1111
*** UnKnown can't find www.google.com: No response from server
I have set my DNS to use Cloudflare, but the same issue occurs when using my provider’s DNS or Google’s DNS. I am able to access and use the internet without issue, indicating that my DNS is working. Can anyone suggest why nslookup may not be working for me? Here is the output of my “ipconfig /all” command:
C:\Windows\system32>ipconfig /all

There are several possible reasons why nslookup is not working for you. One possible issue is that there is a problem with your DNS settings. You can try resetting your DNS settings to their default values by running the command “ipconfig /flushdns” in the command line. Additionally, you can try running the command “nslookup” with the IP address of the server instead of the hostname to see if that resolves the issue.
Another possible issue could be that there is a problem with your network connection. You should check if your computer is connected to the internet and check the status of your network adapter by running “ipconfig /all” command. Also, you could try to troubleshoot your network connection by disabling and re-enabling your network adapter, or resetting your router.
Lastly, the problem could be with the server itself. In this case, you should contact the server administrator to see if they are aware of any issues with the server or network.
