Jon, this smacks of 10base2 network problems so I'd check for dodgy 
connections and especially, correct termination.  If you ping to / from the 
workstations which do not respond for DHCP, what percent packet loss is 
seen?  A less likely cause would be a faulty NIC transceiver jabbering on 
the segment.
