I am running a NW6.5 sp4a 3 node cluster I have installed Zen 7 to it
however I am now having some problems getting the desktop machines to pick
up via PXE if It will return with a error PXE-E53 I have tried with option
60 set and without. Does Imgserv or similar need to be running on all
nodes and what else if so. However, I have a test tree with Zen installed
and if I start zen on that pxe from the workstation will work and the
proxy image server with come from that box what is the cluster setup

Any suggestions please.
