Logging Network interface status

Okay, this should be easy, but atm its eluding me.
I need to log the status (active/disabled etc) for a network interface in Windows XP. ATM I have a continuous ping logging to a file… It works, but its bulky and not so elegant, and the time stamp is plain unreadable =\ Though I can parse it to see if there are any failures, matching it to server log times is a pita.
I just need some sort of proof that the computer in question is not loosing network connection, or, to verify he is correct.
You would think MS would add this functionality to performance logging or event viewer (only logs if iface is disabled or media is unplugged).
Any one have a suggestion?
