Existing tree with an existing ZDM7SP1/NetWare 6.5 server - PXE works
for the XP VMs. All servers/clients are on the same network. DHCP is
running on a separate server.

Added a new ZDM7SP1IR4a/OES2 SP1 server to the tree and shutdown PXE
services on the old server (pxeStop). No DHCP services are installed on
the new server and I have verified that there are no port conflicts via
nmap. I have also disabled the firewall temporarily to assist in
troubleshooting. The novell-proxydhcp, novell-tfp and
novell-zmdprebootpolicy services are running - no errors in the
respective logs.

Booting an XP VM produces the following:

PXE-E53: No boot filename received

PXE-M0F: Exiting Intel PXE ROM.

I bumped the log level for the above novell-* services from 2 to 4 but
after restarting the services, the verbosity of the logs hasn't
increased and i'm not seeing any client requests being logged.

Thoughts? I'm still getting a feel for tcpdump...
