I am using ZLM 7.2 IR1 on a IBM x3650 SLES10 SP1. I am running ISC DHCP on that server. The config of this DHCP is below:

option domain-name "xxxxxx.yyy";

option vendor-class-identifier "PXEClient";

default-lease-time 600;
max-lease-time 7200;

ddns-update-style none; ddns-updates off;

log-facility local7;

subnet netmask {

host c7f14n7 {
hardware ethernet 00:1a:64:23:5d:82;

Novell-ProxyDHCP is also running, and seems to be working.

When I PXE boot the above system (c7f14n7), I get a response from both the ISC DHCP server and the Novell-ProxyDHCP, as I get the following result:

Novell Preboot Server -- <IP of Preboot server>

BOOT SERVER IP: <IP of Preboot server>

Novell PreBoot Execution (PXE) Agent v7.0.0
Copyright Novell, Inc. All Rights Reserved
Sending queries to <IP of Preboot server>

After that it hangs. I am at a loss. I get a timeout message in the zmgprebootpolicy.log file:

Anyone have any ideas??
