I have a website sitting on an IIS 7 server: WWW.example.COM

I would like to create several sub domains that looks like SUBDOMAIN1.example.COM

I created an IIS website and I set the bindings to be http, port 80, the ip address of my server, and SUBDOMAIN1.example.COM and the physical path to a folder under example.COM

I restarted my website and clicked on browse, the browser than opened with the address: http://SUBDOMAIN1.example.COM

But the website doesn't show up.

Do I have to do something with the DNS?

This one drove me crazy... basically you need two things:

1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.

2) You must add an additional website in IIS 7 named subdomain.example.com

  • Sites > Add Website
  • Site Name: subdomain.example.com
  • Physical Path: select the subdomain directory
  • Binding: same ip as example.com
  • Host name: subdomain.example.com
