An IIS website is run via an Application Pool which has its Identity advanced property set to ApplicationPoolIdentity. The website runs PHP scripts via a FastCGI handler. These scripts try to write to a file but the access is denied even the application pool user has enough permission. I have run ProcMon and it shows that the scripts are trying to open the files using IUSR instead of the application pool user.



  • Website example.com

    • Basic Settings - Application Pool = example.com

    • Basic Settings - Connect As = Application user (pass-through authentication)


  • Application Pool example.com

    • Advanced Settings - Process Model - Identity - ApplicationPoolIdentity


  • Script tries to write to a file

    • C:ABCtest.txt


  • The directory C:ABC has permission

    • IIS APPPOOLexample.com - Full control, Type Allow, Applies to This folder, subfolders and files


When I open the scripts url, I get
PHP Warning: fopen(C:ABCtest.txt): failed to open stream: Permission denied



When I run Sysinternal's ProcMon I see:



  • Event

    • Operation CreateFile

    • Result Access Denied

    • Path C:ABC

    • Desired Access: Read Data/List Directory, Syncchronize

    • ShareMode: Read, Write, Delete

    • Impersonating: NT AUTHORITYIUSR


  • Process

    • Path …php-cgi.exe

    • User: IIS APPPOOLexample.com


How to fix it so the file is accessed using the example.com user?
