Aardpsymon:
We typically copy all intallation media to some network storage. We're horrible for keeping track of media... so as soon as I get my hands on it, it's dumped to disk. As we get new versions, I'll either move the old versions to an archive or just delete it.

Caveman:
Thanks for the DHCP tip. I need to move my DHCP servers very soon... but I'm changing IP schemes. I was dredding doing it one by one. I can probably just find/replace in the dumped file and then import that. I'll toy around with it.
