While I have since moved on from Central Michigan University, part of my job as systems administrator of the Woldt Computer Lab was to maintain the lab's Macintosh network.

While your particular lab setup will inevitably differ from the Woldt Lab setup, I hope you'll find a few good ideas to incorporate into your lab's unique needs.
