Running ZENworks in 2 servers!!

I am currently running zenworks 7.0 on OES Netware 6.5 sp5. I had an
idea of running two servers and divide the tasks of each server, meaning
I have one server that is taking care of the remote management, WOL
service, everything except imaging. The other server is just for imaging
running the imaging service and everything. Everything is running
smoothly except when I try to setup a multicast or even give an imaging
job to an individual workstation, when booting from PXE, it comes with an
IP address, but it doesn't get the job to do. I don't know if the setup
I am trying to do is doable, but I just want to know and see if it is
possible if not then I can install the imaging service to just one
server. Any help will be greatly appreciated.

Thanks,

Horacio Hernandez
