php upload files

Hi all a i am running a windows 2003 server with IIS. I have created a php script that uploads a file to a server. in the server i have users and a user1 has permission to folder1, user2 has permissions to folder2. I want an administrator to run the script and upload a file to these foldes. how can the script access the folders that only various users have access? _________________________________________________________________ Explore the seven wonders of the world http://search.msn.com/results.aspx?q=7+wonders+world&mkt=en-US&form=QBRE
