I need an easy utility, either 3rd party or built into Windows 2000 that can resolve an IP address from the MAC address of a NIC. I have been doing it by pinging known adresses and then checking the ARP cache but this get to be very time consuming.

you can use nbtstat -a xxx.xxx.xxx.xxx to get the MAC address from a know IP but I'm not sure of anything that will get the IP from the MAC address.

Ahh that is the trick and what I'm looking for. How to resolve the IP address when all you know is the MAC address.

Hi, this would be the job of rarp (reverse arp). Since arp resolves the mac address to IP, rarp does the opposite. Now NT 4.0 did not support this, but 2000 may (I am on a 2000 learning curve and I'm not sure if 2000 supports this, but it certainly is worth checking). Good luck
