I took over a job at a marketing firm once who had lost their senior developer about a year before. They had been running on luck and a whatever quick fixes their front-end developers could hack together when anything went down. Needless to say, no one had any idea where the servers where or even how many servers we had. Took a while to track them down. Almost a year after I had thought that I had tracked everything down we had an odd error start cropping up on our sites where the domains on a couple older sites wouldn't resolve on just some computers. After digging through it we found that there was some name-server that I had missed but we still didn't know where it was until a thunderstorm killed out office router. In the process of replacing it we tracked one cable to a closet in the basement where, lo, the mystery name server was sitting.
