Windows Server 2003 Access-based Enumeration

Download details: Windows Server 2003 Access-based Enumeration

Overview
Windows Server 2003 Access-based Enumeration makes visible only those files or folders that the user has the rights to access. When Access-based Enumeration is enabled, Windows will not display files or folders that the user does not have the rights to access. This download provides a GUI and a CLI that enables this feature.

This is an awesome update. Windows system administrators have been looking for a tool like this since Windows Server was first released. I don't know why Microsoft didn't 'advertise' this update more. I stumbled across this on Bink's site this morning.
