Unknown Workstations

Thanks for the ideas! The switches are Cisco, but not ours. We were able to get the company that installed the switches to work with us on finding the workstations. Found them, and straightened things out.

You guys are the best.

Happy to hear that things have been sorted out, necronian. Would it be possible to tell us how you went about finding the workstations?

Using your idea, we got the MACs from the DCHP. There was one that didn't show up, for some reason, so we used nbtstat on the name and found the MAC that way. The switches belong to Knology, so we had to depend on them to tell us which ports those MACs were connected to on their switch (this took a little time.) After that, I had to have one of the electricians (who pulled the ethernet in the building) walk around with me with a map because the walljacks were not marked in the plates themselves.

Now, the only part I did personally was the nbtstat and the walk around. I didn't get to sit in on the snooping of the switches, so I don't know how it looked.

Thanks for that necronian. I hadn't actually used nbtstat before. I usually use the "arp" command to retrieve MAC addresses. I did some "google" research on nbtstat and came up with nbtscan . This is a free software utility that runs on Unix/Windows and allows you to scan entire IP networks for NetBIOS name information including MAC addresses.
