Thanks for the help.  We have 3 network interfaces on the boot server. 
hme0, hme1, and hme2.  hme2 is doing the DHCP, and is on the "81" 
network, hme0 is on the "83" network and serving TFTP.  The machine we 
are building is on the "81" network.  In the dhcpd.conf we had the 
next-server line explicitly pointing to the IP address for hme0 (83 
network).  After I removed that line and restarted the dhcp server, it 
worked fine.  So it seems that for some reason the PXE stack doesn't 
like having a next-server line if the machine being built is on the same 
network as the DHCP server.  That really doesn't make any sense to me. 
But it works now :).
