Use this tool to determine the current access levels of each user. It wont give you the magic answer but it will help you quickly determine ACLs.

Intro from the DL page:

While the flexible security model employed by Windows NT-based systems allows full control over security and file permissions, managing permissions so that users have appropriate access to files, directories and Registry keys can be difficult. There's no built-in way to quickly view user accesses to a tree of directories or keys.

AccessEnum gives you a full view of your file system and Registry security settings in seconds, making it the ideal tool for helping you for security holes and lock down permissions where necessary.
