x64 edition running 32 bit PHP issue

Recently I have found a need to install PHP on one of our web servers. The issues that have been cropping up with this installation have been a head ache and until this point solvable with a little google grease and some problem solving. However I seem to have hit a road block. Im not extremely familiar with the workings of servers in general and intalling PHP and getting to this point has been a great learning experience.

So i've got it working, sort of the .php sites are being found but im getting a 500 error. Now the tutorial I had been following

(http://www.peterguy.com/php/install_IIS6.html#phpConfigure)

suggested changing the configuration of my server using a CScript command. However when I execute the command

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1

my server does something funky and it no longer serves any of the files, you can't access the main site via ip or http nor can you access any of the files in the directories. I have a feeling that this has something to do with the 32 bit emulation but I am at a complete loss as to what to do next. Resetting the 32bitappon64 value to 0 fixes the issue but then I get the 500 error again and can't run my php scripts. Any helpful hints or instructions would be greatly appreciated.

 

To be more clear, the error I am getting is not with PHP. I run the script to start the 32 bit emulation and my server that was working just fine hosting the pages but returning 500 errors for my php pages (because they are 32 bit programs) begins returning a service unavailable error is there any service or ultility I may be missing?
