HTTP Error 500.19 - Internal Server Error The requested page cannot (WCF + REST + IIS7 + SSL)

I am having a "dandy" time trying to get my WCF REST service hosted on IIS with SSL.

Environment: I am testing on a Windows7 box with a local IIS server. I have self-registered a certificate on my dev box and have:

1. Created a site in IIS for the purposes of exposing this WCF service via HTTPS.
2. Created an application under this site and named it "api"
3. Navigated to my site in IIS
4. Clicked 'Bindings...' in the Actions panel on the right.
5. Clicked 'Add'
6. Selected 'https' and selected my certificate.

A lot of the REST plumbing is handled via extensions in WCF using the WcfRestContrib library. While this has been useful from a programming point of view, there is little out there in the way of documentation when something goes wrong.

The error I am currently getting is:

Error Summary

I am really not surew what I am doing wrong here. So far I have tried resenting feature delegation for my site but that didn't work. Any ideas? Anything look odd in my web.config?

Thanks.

It looks very much like this thread

The proposed answer was

1. Right click the folder where your site is located: "C:\Users\NAME\SiteName" and selecting Properties
2. Select the Security tab and click on Edit
3. Add.. and type in "IIS_IUSRS"
