arpwatch doesn't run on windows, but if you have other boxen on your network, it might be of use to you. (note: IP has been inferred from your question, but not stated. Windows has been inferred, though the OS running on the PCs is also unstated.) arping also has a dependency of unix or unix-like OS. Both tools provides output that predictable and therefore easily parsed by perl.
