PHP Permissions on IIS

I have no experience using PHP on IIS but a customer is having a problem so I have been forced to try and understand how it works.

The problem I am having is with permissions. My program tries to upload a file to a specified folder. In anything other than Windows I can just chmod 0777 and everything will be fine.
On IIS I have to used their web-based “permissions manager,” but it doesn’t seem to work. The only options you have is for “read” and “write” access. I have granted both read and write access for every user and applied the permissions to every sub-folder but I am still getting a permission denied error from PHP when I try to upload the file.

Does anybody have any tips on what I might be doing wrong?


What version of IIS?

It’s IIS 6.0 running on Windows 2003.
