My 'office' is a corner in the IT suite so I can't hide!! I've been working as a Technician for a year now and C2k is a double edged sword. In one hand you don't have to do a whole lot since if something goes wrong all you have to do usually is phone the helpdesk. The only thing is, you don't really get to improve your IT skills because you aren't allowed to do anything!!
If your school has a legacy network, get your hands dirty with it. I installed a Linux system on my Legacy network which kept me busy over the summer, but now its up and running, there isnt much to do on it until it gets an overhaul this summer again.
My advice to you is avoid teachers like the plague, you just would not believe some of the things they ask you...........
Good luck!
