I am trying to find a way to resolve MAC address to ip address (or to Computer Name) on my enterprise network running windows server 2003 and XP.
I have a bunch of mac addresses from one of our switches but no IP's or computer name.
Is there a command or tool that will do this?
I already know how to resolve IP to MAC but not the other way around.

Command:
arp -a
lists the IP/ARP correlation table currently in the computer's arp-cache. Try that first and then you could try pinging all IP's and then doing "arp -p".

Instead of attempting to manually resolve, just login directly into the switch. You should see somewhere within your management interface depending upon the type of switch, a listing of IP's and MAC addresses associated with the IPs.

If you are running Cisco switches you can find out the ip address if you know the mac
show arp | include <mac-address in xxxx.yyyy.zzzz format>
You can also do a partial mac in the command as well and it will return the corresponding ip/mac relationships.
If you do this on a regular basis or need to, there is a tool by ManageEngine which will do switch port mapping for you. It will tie the ip address, mac address, and tell you what port the device is plugged into. www.deviceexpert.com

Yeah that's what we ended up doing. I knew about exporting the list in DHCP but that wasn't what they wanted until i showed them it was the easiest way to do it.

Checking the DHCP won't reveal MACs of any fixed IP-addresses though.
