I've moved to a new host provider and on my last host provider they'd configured all sub-domains that don't exist to map to my base domain.
Aka,
products.searisen.com doesn't exist, but it would call searisen.com and then my default file would handle the request for it.
My new provider has me manage the IIS myself and I'm a newb at it.
I'm using IIS Manager.
Edit: It's a shared site.
Edit: The shared site is on a Windows 2008 IIS7 server.
Thanks
