[syslinux] Has anyone any insight as to why RedHatEnterprise Level 5 is broken as far as PXE booting is concerned.

Client recieves fixed address of  172.16.0.30 bound to mac 
"00:01:6c:ca:24:7b "of client
So that works.

ditto
Client recieves fixed address of  172.16.0.30 bound to mac 
"00:01:6c:ca:24:7b "of client
So that works

The DHCP server is on box  with ip of  172.16.0.254 with  00:02:B3:99:05:A0
The TFTP server is on box  with ip of  172.16.0.254  with  ditto

Yes I tried to find info on next-server but couldn't find a search function 
on the list.
So downloded the last 3 months archives uncompressed them & searched for 
next-server but haven't yet found much info.
I tried the next-server set as  below with the other 2 commented out .. with 
no joy. so I tried  (didn't make much sense) all  3,  also no good.
Obvioulsy  I really don't know how to set the 3 below options.
Should I put the tftp server on a different box?
Is the "next-server" simply a DNS server?  if so how ........

         next-server 172.16.0.254;
      #    hardware ethernet 00:02:B3:99:05:A0;
      #    fixed-address 172.16.0.254;

Thanks for your reply   XL
