We have identified an IP address on our network that is constantly requesting an IP address lease from the DHCP services that are running on a Netware 6.x box.

We've identified the MAC address of this machine, however can't seem to find it on the network.

The display on the DHCP Mgmt console doesn't show a true host name (it shows garbage) and the usage tab just shows the address to expire one minute ahead of when I'm looking at it.

We are using a packet sniffer on the switch to identify the IP address, however since we can't find the particular machine we don't know which port in the switch it's hooked to.

Does anyone know of a sniffer that can sniff by MAC address?
