No boot filename received

I am running Zen 7 sp1 on a Netware 6.5 sp3 box and trying to use a PXE
disc. I am using a Dell Latitude CPx laptop to test this. When it boots
from the disc it gives me the error, " PXE-E53:No boot filename found".
The only TID I found was old and talked about back revving some of the
imaging components. I had this same problem with pre-sp1 7 too so that
makes no sense. Any ideas?
