IIS / PHP / mkdir - cant create
 

OK so I've done something to the permissions of the wwwroot folder on a server.

If I want the admin side of a site to be able to do mkdir and create files from php only within a gallery folder and any subfolders, what do I need to do with the windows permissions.

Basically mkdir() wont work, tried with trailing slashes, quotes, 0777 but it simply wont work.

Do I have to enabled IIS user full control of the gallery folder and replace on all child objects?

This is driving me crazy. Please help.
