Do you have questions like:
Who has access to this file?
What does this user account or group have access to?
If so, take a look at this description of NetVision's latest - free reports that answer complex questions. Or to get started right away, go directly to the TryIt! edition product page.
It's nice to have something free to give away that is actually useful.
Two reports provided that every admin should care about are:
Direct User Assignments – report on all instances of permissions being assigned directly to user accounts (instead of via groups).
Explicit Deny Entries – report on all instances of explicitly denied permissions (these can cause headaches when trying to figure out why someone doesn't have expected permissions).
