Speaking of scan tools, does anyone have recommendations for tools to do baseline configurations on Windows systems? Looking for pre-change configuration baseline and post change configuration baseline - to identify differences implemented by the change?

Network scan tools are a great way to verify what important protocols you left out of your control plane policing non-default policies.  Had a scanner totally clog up our 6500 core router DHCP relay (ip helper) function once.
Uggghhh, security people....
