I'm running a site on my dedicated server with windows server 2008 , iis & dns has been installed without any configs, have one dedicated ip address.

when I type the dedicated ip of the server in a browser, I can see my website working OK.

I have a domain registered with a reseller and I'm attempting to have the domain resolve to my server (built-in localhost website).

How do I properly setup the ns1 & ns2 nameservers and web zones for that domain , so its publicly live and view able? 

I have access to my registrar panel that enables me to change DNS of registered domain to ns1 and ns2. 

summary : how to create these ns1 and ns2 in my server?
