PHP FastCGI on IIS 7.0

So to give you a little background on a server issue, we were having problems with PHP running on IIS 7.0. PHP would run fine on some apps but did not run at all on others. We searched back through the code and all was correct. What could cause this?

Seems that PHP on IIS 7.0 with PHPFastCGI does not like the expose_PHP = On
line in the php.ini file. We changed the setting according to Microsoft Standards and viola PHP runs fine.

It is unknown to me why this is. Still doing research on this. Thanks
