I have a several users or locations showing on our network that don't exist. How do I fix these or remove them?

Is there a Active Directory domain? What machines are on the network? Exactly, where are the names & locations seen? Did they exist at one time or are they totally fake? How do you know when a politician is lying? His mouth is moving.
Or by locations do you mean wireless networks? It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.***William Henley***
