I've been trolling around the boards for a day and neglected to introduce myself.
I'm currentlly a enterprise desktop architect for a large health care orginazation in the eastern half of the United States. Most of my OS experience is in Microsoft Systems, this is not by choice but I am a firm believe that you don't bite the hand the feeds you. I'm currently working to complete my BS in ISS and continue to work through my certification alphabit soup.
There is a wealth of OS info here, especially in the *nix area.
