Do you mean tcpdump from the ISC DHCP server, or some networky
packet sniffer on the 202 subnet?  Our network guy is contemplating
the idea that somebody attached a rogue dhcp/wireless/NAT device
to the 202 subnet and disrupted traffic there.  This issue just 
started today.  Since it is near the start of school, new people
and new devices are showing up on our network...
