You can see the name and IP where?? DHCP? DNS? ADUC (which usually doesn't show IP addresses?) The question is vague and so far the goal isn't clear.

Well, if it isn't in DHCP, DNS, or ADUC then it *probably* means someone simply plugged in a device on an unsecured port or on an unsecured AP. An IP scan doesn't mean the device is in AD. So removing said device can take anything from physically inspecting each switch and securing APs to using something like 802.1X or MAC filters to attempt to lock things down.

You could inspect your switches' CAM Tables to find which switch port the device is on, look up which physical wall port that is, visit it and then give the person responsible a clip round the ear  :)
