PHP5 on IIS7 - Inetserver

It seems like you are using PHP5 ISAPI, and it is failing with
0x800703e6 (Win32 Error Code 998 = Invalid access to memory location)
after IIS7 executed the PHP ISAPI DLL through the ISAPIModule module
in the ExecuteRequestHandler event.

I don't think this problem is within IIS7. Assuming you are still
using the same PHP binary that was once working, I would start
checking PHP configuration changes that could result in this state.
Your IIS configuration is fine because PHP ISAPI DLL is executing --
most people get confused and never get to this.

GDay All,

Seems that I have solved my own problem.

It appears that Vista marks some foreign files as blocked whenever you copy
files to the C:\ Drive. Checking each file (from Windows Explorer, right
click on the file and select properties) shows that the file is blocked.
Clicking on the unblock button allows that file to be accessed.

I had to do this for each and every file in my php folder, but I eventually
got php working! Yay!

I experienced the same problem getting "PHP Version 5.2.14" with IIS7. The PHP isapi filter was being called but something in the configuration was throwing the 0x800703e6 error. I got past the error by commenting some of the "Local Variables:" defined in the php.ini file.

I started by commenting out all the "Local Variables" then slowly put them back in one at a time.

These are the ones I had to comment out:

;[PHP_OCI8]
;extension=php_oci8.dll

;[PHP_PDO_OCI]
;extension=php_pdo_oci.dll
;[PHP_PDO_OCI8]
;extension=php_pdo_oci8.dll

;[PHP_PDO_SQLITE_EXTERNAL]
;extension=php_pdo_sqlite_external.dll

;[PHP_PSPELL]
;extension=php_pspell.dll

;[PHP_SYBASE_CT]
;extension=php_sybase_ct.dll
