move_uploaded_file - Permission denied

Hello, I had created a website some weeks ago on my Windows XP Professional computer using IIS and PHP4 before I did format c: and reinstalled XP and IIS. Now I'm using PHP5 and move_uploaded_file does not work. I don't why, because the specific folder has read and write access. But I always get the following Warning: Warning: move_uploaded_file(full/1.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in c:\Inetpub\wwwroot\file-upload.inc on line 76 Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'C:\inetpub\php\uploadtemp\php1BD.tmp' to 'full/1.jpg' in c:\Inetpub\wwwroot\file-upload.inc on line 76 The paths are correct because otherwise the message would be "No such file or directory". Here are some more bits of information: Directory to upload: C:\inetpub\wwwroot\bilder\full ( READ + WRITE access set through ISS console) PHP-Temp-Upload: C:\inetpub\php\uploadtemp Can anyone help me? Thanks in advance, Henning
