I wonder if anyone can help me with this.

I have a machine on my network (of about 100 machines) that apepars to be generating alot of network traffic. Unfortunately my network monitor just shows its mac address rather than its ip address which means that I cannot work out which machine it is.

I have been told that what I really need is a RARP tool (reverse ARP) to resolve the mac address to an IP address but all the ones i have found so far appear to be for unix or linux which we don't run.

Does anyone know a good RARP tool for Windows? Or a different way to resolve this mac address to it's ip address?

Thanks,

James.
