Without changing a single file or setting on IIS, I'm getting 404 errors for the root of my site. FREB is turned on, and it seems the FastCGIModule is involved somewhere.
I run Drupal, installed via WPI, and PHP 5.2.9 also installed via WPI. When attempting to access /index.php I get a 404 error. Because I can get to install.php, but update.php?op=info returns a 500 server error, I think that there could possibly be some sort of rewrite error, but I'm not sure.
The trace looks like this:
