Permissions on each folder

The tool I have used in the past to get folder permissions is cacls. This is a windows tool and it does a decent job of giving you information. However, you cannot use share names as targets, you have to actually hit the drive(s) on the server(s) to get the ACL data.

EX: cacls \\servername\e$\*.*

This would give you the permissions for files and folders at the root of E on the specified server. You can also add directory names and go deeper. There is no switch for recursive processing, so it does take some time. I recommend creating a batch file and having it populate a text file. Run it at the end of the day and check the file the next morning.
