Just thought I would share this little gem I stumbled on this afternoon.
http://www.howtogeek.com/school/sysinternals-pro/lesson1/
"This How-To Geek School series will teach you how to use SysInternals tools like a pro, so your geek cred will never be in question. Not that we are questioning your geek skills. You do use SysInternals tools, right?"
Looks like a really good overview/tutorial.
