Here's a kicker that happened to me just the other day....
I bought an APC BX800 for a server that I mantain for a computer center. I plugged everything in, only to find that the "Faulty Building Wiring" light came on. So I called an electrician to come out and see if we were missing a ground wire or something. Well, he decided that he needed to switch the breaker off without asking anyone first. Sure, this would have been ok if I had plugged the server's power cord into the battery backup part of the UPS, but it was only plugged into the surge part of it. DOH! For some reason one of the hard drives in my RAID 1 switched to RAID 0! I don't know how the power outage effected it in that way, but it did. I had to delete the RAID 0 array, and rebuild the RAID 1 array, which thankfully worked (although it took about 3 hours).
Oh yeah, and then once I rebooted into W2k3 it was only to find that my Active Directory was corrupt, and I hadn't made a backup yet. And thus, I did a full re-install.
Leasons Learned: 1) Make sure you plug the computer into the battery backup rather than just surge protection on an APC. 2) After you build an Active Directory make sure to set up a backup routine. 3) Install the APC software immediately after the APC. -- If the computer HAD actually stayed on during the power failure, I hadn't installed the software for it yet, and so it would have eventually crashed rather than shut itself down with 5 minutes of the battery remaining like it does with the software installed.
All in all, it took about 10 hours to get everything back up and running.
