Fixing a failed Hyper-V Guest Network Adapter

Sometimes you have a day when you think, “Why did I ever get into IT?”. Just when everything seems to be running smoothly an unexpected “blip” happens that seems to have no logical explanation. Then you remember that you sadistically enjoy solving these ambiguous problems and you start to dig.
