Recently I was onsite with a client doing a pet test when I came across a production server running NT 4. It was a PBX, supplied by a vendor, and therefore unable to be administered or upgraded by the client without voiding the warranty. Amusingly, the company I was at had only existed for about two years; which means that at least sometime in the past two years, there is a company selling a PBX appliance that runs on NT 4 (I don't even know how they can get a license for it). Off topic; port scanning it was like trying to remove yourself from a landmine that you stepped on. It required action-movie dexterity.
