The Problem
The other day I was attempting to fix what appeared to be a configuration issue with our farm. We were receiving version mismatch errors when running code within our farm. It turned out there was two problems. First the farm did indeed have a misconfiguration (I am writing about that one separately) and it was found one of our servers in the farm wasn’t functioning properly due to a recent patch not applying properly. This post discusses the steps I took and the end result.
