Good point about the not-yet-stale IP lease in the old subnet.
However, when I changed the subnet, I took down the network
for about five minutes thinking the clients would issue a new DHCP
request when it came back. I've witnessed that behavior on
my home PC when I unplug the switch.

The funny thing is that the "conflicting IP" popup was, in fact,
appearing on multiple machines. That's why I think there was
something nefarious running on the suspect machine.
