I just did a clean install of Orchard into a load balanced environment (2 - 2008R2+IIS7.5 servers, 1 - SQL 2008 server). All files reside on a shared network folder and I configured the machine key as the docs indicate.
However...when browsing to my site (unauthenticated) all the pages are ugly (not themed) and I get the following js error:
Webpage error details

If I try and navigate to the /core/shapes/scripts/html5.js file I get an access denied error and am redirected to the login page. If I am logged in things look fine both in the admin pages as well as the regular pages.
