trace MAC address

[fc]

I got a ip address conflit this morning on some of the
server with static ip assigned. I checked event viewer
and get MAC address of the unknown PC. How could I trace
with the MAC address I known to know the pc still on our
network.

If you are connected to a managed switch, you can lookup the MAC in the CAM
tables. This would lead you to the port that the offending NIC is on. This
doesn't work very well however if you have a hub or unmanaged switch plugged
into that port.

Alternatively, you look for a RARP program ( Windows does not come with
one ) which would convert the MAC to an IP. then you could Ping -A the IP
returned to get the hostname.

It's also possible to look in the ARP table and search for the MAC (
ARP -G ). The MAC will only be there if it has communicated with the
machine you run the command from directly.

Change your IP to something else for a minute (be ni the
same sbnet), and try pinging your original IP with -a and
get the name. wild guess..
