IIS 6.0 with PHP and FASTCGI - error exited unexpectedly

I have a windows 2003 server using IIS6 and PHP. I am using a PHP Framework and on loading a page of the framework, after 15 seconds I get the following error:

FastCGI Error

The FastCGI Handler was unable to process the request.
Error Details:

The FastCGI process exited unexpectedly
Error Number: -2147467259 (0x80004005).
Error Description: Unspecified error
HTTP Error 500 - Server Error.
Internet Information Services (IIS)

My Fast CGI settings are as follows:

[PHP 5.3]
ExePath=c:\php5.3\php-cgi.exe
EnvironmentVars=PHPRC:C:\php5.3
IdleTimeout=9000000
ActivityTimeout=900000
RequestTimeout=900000
InstanceMaxRequests=10000

Does anybody know whats going wrong?

UPDATE

After looking at the Event Viewer, I can see the following error: Faulting application php-cgi.exe, version 5.3.9.0, faulting module php5.dll, version 5.3.9.0, fault address 0x00091818.

What exact version of PHP are you using?

You should use the VC9 versions, to use PHP with IIS.

Also you will need to have the Microsoft 2008 C++ Runtime installed:

x86 version: http://www.microsoft.com/downloads/details.aspx?FamilyID=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en

x64 version: http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6&displaylang=en

Also, if register_globals is set to 'On' in php.ini, you will get this error.

0x80004005 is normally a security issue.
