I am using IIS7 on Windows Server 2008r2. I have recently installed php and IIS. I am trying to browse to the index.php but it returns a blank page. It loads the favicon and the header of my page. When I load an info.php file it is not blank. If I disable Anonymus Authentication it the same index.php returns IIS 7.5 Detailed Error - 401.2 - Unauthorized. What is strange is I installed this exact code onto another fresh IIS install I just did and it loads fine. Permissions for the directory are the same for both.
