Thanks David.

My arpwatch file confirms TruemanLT-PC was the last machine to use 
192.168.37.132 (on 30 March 2007) before it was assigned to the PC 
with MAC 00:19:d1:82:7a:17.

Thanks for responding Niall.

No.  I should have mentioned I was using that PC at the time and had 
just booted it from a NetBSD installation CD and run dhclient.
