I have no idea what I'm doing inside IIS.  I don't even know if my terminology is correct.

(using IIS 7)

When installing some software that runs a site, the site gets put under the default website, making it "mysite.com/newpage"  (I'm calling that a nested page)

I want to make that it's own root site, like "Newpage.Mysite.com"

How do I move it in IIS?

I already have the DNS record created with GoDaddy, already have NAT'ing setup for the site that I want to create, just need to get it created the way I had envisioned for all that to work.  

Should be called a subdomain?  (not certain, I'm more of an apache guy)

Bingo - Subdomain is the word I'm looking for.  Thanks!

Been a while since I used IIS7, but I think it's close to 8.

You want to create a new site (right click Sites -> Add Web Site)

Use whatever you want for a name and set the physical path to the root of where the app web files are installed.

Under the site binding is where you define the host name, they give an example but you would enter newpage.mysite.com

You will also need a DNS record pointing newpage.mysite.com to the IP address of your web server. If this is all being done local, you can modify your hosts file and create a manual entry.

*edit - sorry, missed your note about DNS already being set up with godaddy

This is not an IIS problem.

 

This ^
And what shnelson said.

Trying to do anything with the existing page/site just broke it.  Ended creating a new site, then just copying the defaultly installed as far as directories and applications.  

I'm up and running now. And know a wee bit more about how IIS works :)
