NSLOOKUP PROBLEM

Hi,

Thank you for posting your question in the Microsoft Community Forums.

Appreciate your efforts to work on this issue.

I would like to let you know that nslookup is a command line tool which helps you to find the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. It can also perform some other complex functionality
like finding details about FTP server, Mail server and so on, but most of them are used by IT administrators. It also queries the DNS server directly and doesn’t rely on the cache.

You can refer to these articles for more information.
