IIS 7.5 PHP failure “The FastCGI process exited unexpectedly”

\"HTTP Error 500.

I know its an old thread, but someone might save some headbashing.

In php.ini, changing

; Whether or not to enable the dl() function.  The dl() function does NOT work
; properly in multithreaded servers, such as IIS or Zeus, and is automatically
; disabled on them.
; http://php.net/enable-dl
enable_dl = Off

to

Having enable_dl = Off doesn't work, commenting out the entire line does.
