My dream job while in college was server admin. I had done it during the summer as a student and really liked it.
When I graduated I started off at the help desk for a few years then moved on to server admin, but at a customer site. The job itself was nice but the environment was really poisoned. I left it when I saw a NOC position come out, it's more telecommunication than IT, but I learned it, and enjoy it now, been almost 2 years.
I like playing with server stuff at home but realized it's a totally different beast in the corporate world. Too much politics.
