IIS Lockdown Tool

[Guru]

This tool lets you instantly configure an IIS 4.0 or 5.0 web server for secure operation. It provides two modes: an express mode that is appropriate for most basic web servers, and an advanced mode that allows the administrator pick and choose the technologies the server will support. The tool provides an undo feature that allows the effects of the most recent lockdown to be reversed.
