Why is it that I have a machine that, for all purposes, appears to be on the domain yet I can not find it anywhere in AD? The machine states it is on the domain. Domain users can log onto the machine with their domain credentials. They can access resources while logged on. Yet, if I search within ADU&C and within Hyena, that computer name is no where to be found? It is not in the transfer group, it is not in the built-in computers group. It is not in any OU.
