I love how people ask me questions like, "What's ISAM Error 101 mean", like I remember 200 plus error codes from the DB backend this company used for it's MSDOS releases.

"ISAM Error 101 means STOP RUNNING YOUR COMPANY ON A COMPUTER THAT IS OLD ENOUGH TO VOTE"

That's the correct answer to the question, actually. I just have to frame it with a little diplomacy.
