Active Directory Explorer

This tool (from Mark Russinovich and Bryce Cogswell) is basically ADSI Edit on steroids.
It allows you to connect to your AD environment directly thus providing you a “raw” view
of your directory and in turn the ability to change the directory directly(which might cause a lot
of pain since you are working without the net provided by the traditional AD tools).

A feature of this tool that seems extremely useful to me is it’s ability to take a snapshot
of a directory (and then another snapshot) and eventually to compare the two snapshots
providing you with a list of what has changed.

The tools ability to filter the results and to provide a very focused view of what has changed
makes this tool very useful even in dynamic environments.
