there is a device using one of my DHCP addresses which I don't know what it is, why, because it's not even listed under my DHCP lease pool. I found out about it when I got a message on a machine saying it has a IP conflig on the network. the service seen that IP as not been used but I can ping it. keep in mind I assign my servers and printer with different and static IPs.

how can I identify this device and hopefully locate it. I do have it's MAC address.

Is it listed under Dhcp reservations?

One thing to try is to look on your switches Mac address tables and find out which port that mac address is off of.  If you know the port you should be able to trace the port from the switch to physical drop, assuming this is a wired connection.
