IIS 7.5 error 500 in fastcgi module after upgrading wordpress to 3.0.2

Question

I am running multiple wordpress blogs on the following setup:

Server 2008 R2; IIS 7.5; PHP 5.3.3; MySQL 5.0.7;

I upgraded my wordpress install from 2.9.2 to 3.0.2 (on 2 different sites) today and the upgrade went fine. I can serve .php pages without errors, log into the admin system etc. I can browse my blog by going directly to mywebsite.com/index.php, but when I try to go to mywebsite.com (without the index.php) I get he below 500 error.

I reset IIS, removed and re-attached the default document, but I am running out of ideas.

Please if anyone has a solution for this that would be great.

This is the 500 error I am getting:

Error Summary
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.

Solution

Open your PHP.ini and look for the "error_log" value. Make sure it points to a file where the IIS worker process can write. Also check the "error_reporting" value and make sure it includes "E_ALL".

After that, open the file pointed at by the "error_log" value: it should contain more information about what broke.

Looks like it might have something to do with permalink redirects, I am using IIRF to do the redirects and not of them are working anymore anyone could see how that is related?
