How to set up subdomains on IIS 7

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

Wildcard method: Add the following entry into your DNS server and change the domain and IP address accordingly.

*.example.com IN A 1.2.3.4
