It had an open file share, containing some Delphi books and from which we got the computer name too. So we walked over to the Delphi team's side, and kept yelling the computer name until some dude said "Hey, that's me!"
Turns out he was running a test-case, in an infinite loop until it worked (because that's how test cases worked), and he thought he was pointed at QA, but he somehow had it set up to target Prod.
Our job was done at that point, we left the rest to management (who made sure he didn't get fired but didn't do it again).
Reminds me of that Linux compromise years ago where they picked it up because the change was directly on the build box, except at least that one was hidden behind an apparent `=` vs `==` "bug" - this one has a bit less style.
