User Management NT 4.0 (New Here)

Up until recently we had a pretty good track record, maintaining our user list, but as with any company, we've also had somewhat of a revolving door, when it comes to users. we are also weeks away from our corporate IT and data center audit. Although we could build a spreadsheet and the data manually. I was wondering if there is a product or plug in for user manager, that allows us to compile a list of our users, their specific groups, and their rights on our network?

Similarly might there also be a package that can generate a report on our shared directories and the groups and individuals who have rights to them, and just what those specific rights are.

I happened upon this site, and thought that it might be worth my while to ask if any of the members here, might have an recommendations?

The NT4 Resource kit comes with a utility called addusers.exe, this allows you to do a bulk import of users to an NT server, it also allows you to create a text file which will show all users, groups and who is a member of what group.
