Well, the DHCP backup script that I put in place at my current client ws a life-saver this morning. All of the scripts that I threw together are extremely simple to put into any environment and I encourage you to check them out if you haven't. You can find them in my “Shell scripts“ article category.

Our Primary DHCP server was rebooted this morning and for some reason it decided that bits of our scope configurations weren't valid anymore. So it decided to delete a number of scope options, delete a ton of reservations, and change the IP ranges for a few scopes to 0.0.0.0 through 0.0.0.0. Needless to say, we started getting calls pretty early.

But we were able to re-import all of our settings from yesterday (actually from this morning at 5am since that's when I have the scheduled task setup to run) in a matter of minutes. I'm not sure what we would have done without having the scripts in place.
