Permissions Summary

Is their an application out there that will recursivly scan all NTFS permissions in a Win 2K3 Server outputing a summary report of which local/domain user/group has access to what directory. Preferably giving me a resultant set of rights for each user.

I know the Resource Kit offers command tools such as SHOWACLS and a few others that can do some of this for me, but I'm trying to avoid too much manual work as possible.
