if you want to split dhcp/tftp and nbd server you need to add:

nbdroot="<serverip>:<nbdport>" to your pxelinux.cfg/default file in your
tftp dir (nbdport is usually 2000 by default, each subsequent image
served from the same server will add +1 to the portnumber)

though note that this split really doesnt gain you much, and its painful
to have to update the configs manually in two places all the time ...

keeping the nbd image on the same server as tftp and dhcp really makes
sense, you usually dont change the nbd image anyway after the initial
confguration, since all it does is fire up X, LDM and some basic
services for hardware enablement (i.e. sound and local devices) on the
client ...

the actual application server you use is the server LDM then logs in to
and where the actual desktops run ... 

aiming for a three server split instead of a two server split provides
to be painful in maintenance though indeed it is possible with the right
setup ...
