Here are the 2 new KB articles I'm linking to:

XGEN: You Receive a "The 'SendUsing' Configuration Is Invalid" Error Message If You Use CDOSYS and Outlook 2002 (Q322338)
SPS: The Inheritance Overrides Dialog Box Appears When You Use the IISLockdown Tool and Microsoft Baseline Security Advisor (Q323215)

And the Web Part, shared with the rest of the community by Richard M. Beyer:
SPSFAQ090122 - Can I open a folder from the Dashboard in a Web Folder?
