I've just upgraded to php 4.4.9 on iis6/fastcgi and an image uploader app is now broken. The code creates a directory with: mkdir($dir, 0777)
The permissions appear correct on that created directory, but the files that are uploaded into it now do not have the correct permissions.
Instead of having admins, users, iusr_host, system & iis_wpg, it has admins, power users, network service & system.
Thanks in advance for your help!
