Two PC names, Same IP Address, why is this?

We have two workstations, say Terminal A and Terminal B.

The name Terminal B was once used in the past but is now a dead computer name (as far as i know) When i ping Terminal A, which is a current workstation I get the correct IP address. However when i ping the name Terminal B it comes up with the same IP address that Terminal A has.  How can this be?? Terminal B is not listed anywhere in DNS, yet it is resolving to an IP address that already belongs to another station.

    Accepted Solution

    Somewhere in your HOSTS file or your DNS listings you have a cross reference of the old system to its old previous IP Address

    This might happen if the local PC's ARP cache has not updated itself, check this for more info:
    Check your ARP tables, if that is the case using these commands:

    Also try pinging Terminal B from couple of other PCs to confirm if it returns duplicate IP from all PCs.
