How do I analyze directory-level permiss

We’re beginning a large data/permissions analysis & cleanup project in our existing Win2K environment, so we can implement a full active directory organizational structure.

I haven’t found a way to report on the permissions attributed to each directory though, other than manually reviewing & documenting them one at a time.

Does anyone have any suggestions or know of any tools that would report this data (I can manipulatable the data myself in Excel if necessary).
