Find physical location of network device

I have a device that shows up on my network with the name “AP4”. I can see the ip and mac address on the dhcp server. I am running a win2k AD domain. I am pretty sure its a Cisco Aironet Access point (thats their default name convention). I would appreciate any suggestions on how to physically find where the device is plugged in on the network besides going throughtout the whole organization cube by cube. Thanx
