Sorry for the delay. I couldn't find anything wrong with your dhcpd.conf 
file. The mention of pxelinux.0 should not be a problem.

The best I can determine from the info you've given me is that the 
booting node finds the DHCP server on the first node (you can confirm 
this if it displays the IP address that it's supposed to have) but it's 
unable to talk to the TFTP server on the first node (there is no stream 
of dots on the booting node indicating a download). The problem is 
something that's preventing TFTP from working correctly.

When you installed the first node, did you configure your firewall to 
treat the cluster interconnect interface as a "trusted" interface (or 
disable the firewall altogether)? If not, the firewall code could be 
preventing the booting node's connection request from reaching the TFTP 
server.
