IIS7 Failed to grant minimum permission requests

I had a similar problem when I rebuilt my dev machine with a clean Windows 7 install. After hunting around I discovered a solution that worked for me.

In your IIS application pool advanced settings, under “Process Model”, set Load User Profile to true.

There are some other things to check like your trust level, but none of them applied to me (it was all full trust already on my dev machine). Setting the application pool to load user profile fixed it.
