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
If your computer can't find the IP address associated with SUBDOMAIN1.example.COM, it will not find the site.
You need to either change your hosts file (so you can at least test things - this will be a local change, only available to yourself), or update DNS so the name will resolve correctly (so the rest of the world can see it).
