My ASP.NET MVC2 application with Forms Authentication is blocking access even to Images, Styles and Scripts

I'm developing a MVC2 application and using Forms Authentication on it.

The scripts, images and styles are all blocked to unlogged users and, consequently, the login page looks awful.

It works well local, the problem is when I publish to the server.

Does anyone has any idea WHY????

PS: The server IIS is version 7.5

My Web.config:
