ARP -A lists all IPs and its MAC addresses. Type ARP -? for for information.

This doesn't allow you to search by MAC address though, you have to ping every machine and then do ARP -A to return the MAC address.  What I want to do is query by MAC address, and be told what the IP address is:

ie.

C:\>MACSearch 00-30-A0-0B-CE-F0-A3
MAC Address: 00-30-A0-0B-CE-F0-A3
IP Address: 193.48.126.27

C:\>

Or even better, if there is a windows tool that does this.

you find a trial version of grep for Windows 95/NT at
http://www.unixdos.com/

arp -a | grep 123.23.45.67

the answer is one line with
123.23.45.67     08-20-56-34-23-56     dynamic

BTW: you have not to ping each machine, try ping 123.123.123.0 to ping the network

I get destination host unreachable when I ping 123.123.123.0, I get the same response when I ping our own network

TSchock's answer is same as my first answer, except using filter. In fact, there is no need to use UNIX like command Grep, use DOS Find command instead.
