I have a working site:mysite.com
In the DNS Manager I assigned a Host (A) as sub1 and a IP Address as 192.168.1.xxx close to the IP Address of the Domain.
Then made it a Static IP.
Then in IIS assigned sub1 as a Site added it to an Application Pool and Binded it to *80 under sub1.mysite.com.
I also populated it with a working ASP.net Program just like mysite.com.
But when I entered sub1.mysite.com nothing comes up.
