IIS Configuration Help Please

I would like to setup a few sub domains on my server but my host asked me if my server was configured using Virtual Host or Virtual Domain. Two issues: 1-- How do I find that out? 2-- How do I setup sub domains?

Example: (subdomain.domain.org)

Please understand I am new to IIS admininistration and would not understand known IIS jargon. Thank you for any help.

Virtual Hosting is how you set up the latest versions of IIS to host multiple sites with one IP address... I have no idea what a virtual domain is as it pertains to IIS...

But, in order to set up multiple sites on your server, you just have to add the "host headers" to the sites... host headers are just the addresses you will access the websites by...

So, say you have two domains...

mydomain.com
myotherdomain.com

You want both of those domains to map to the same site... so under the advanced properties of the site, you would put in the proper host headers for both domains.

Then say you also wanted another site called support.mydomain.com and support.myotherdomain.com... they point to the same ip addresses as the main sites, but you give them the "support" FQDN host header, and viola... two sites on one server.

In IIS admin window, right click the website, click properties, click the advanced tab and enter the host headers there...

Note that you can only have multiple sites on Server based Operating Systems, XP, 2000 Pro, cannot do this.
