Windows Authentication Module not available in Home Vista Premium?

I am running Vista Home Premium and am attempting to set my machine up to do
some IIS 7.0 development using Visual Studio 2005. Ive followed the steps
outlined in the following article:

Ive also applied a hotfix that enables debugging without requiring windows
authenticated authentication:

Which leads me to my question/problem. When I go into Windows Features,
under IIS, World Wide Web Service, Security, I dont have an option to select
"Windows Authentication". Does anyone know of a work around that will
enable me to have windows authentication as an option under Vista Home
Premium? I'd hate to upgrade to "Ultimate" just for this.

Thanks in advance!
