I installed at my office a sniffer on a host in order to see just what's happening on the network in order to detect broadcasts etc. And I had a packet indicating a duplicate ip on the network. In short I have two hosts (one server) that have the same ip.
My problem is the following:
I have the ip of the two hosts (for that is the same), I have their MAC address (sent by my sniffer), I identified one of the hosts, and I would identify the second (in order why it has the same address and if this is normal or to change where it would not).
So my question is simple: Do you know a way to retrieve the NetBIOS name of a host from its MAC address? Note that I can not stop the server, or at least change their ip.
