A co-worker has put up a few post about Windows that are well worth the to time read:

• Server 2008 R2: Active Directory Functional Levels
• 2008 Server to the Core
• Who’s Being Promiscuous in Your Active Directory? <- Great for finding sniffers and who’s running VMware in you environment.

@mmurray: Sickest blog post of the year - @cneckar explains implementing a sniffer without privileges. http://bit.ly/LtLZO
