This reminds me of something dumb but I didn't do it, but I did get to fix it. At my old company, we had a file server set up where the IT dept got to put files. This was not on the domain network at the time as we had two networks (and two internet connections). One was for sales and the outward facing servers, the other was for the tech department PC and the deployment network. At some point we decided to redo the network and move this file server onto the domain. So we hooked a monitor up to it and booted it up to join it to the domain. Well that's when we discovered the problem. The original user account that it was set up with didn't exist, and the default one was suffixed with "II" ... so we couldn't log into it. After we got into the OS, a horrible truth was discovered.... This particular PC (being headless) had been running as an Unreal Tournament dedicated server for at least 5 years! After all the data was backed up, we wiped it out and reloaded it, and put all the data back. Since I was in charge of naming the servers in the tech department, I wrote up a survey with a list of possible names and passed it out. When I collected all the results, the new name became "Redeemer" which was appropriate considering the prior circumstances.
