I am running NetWare 6.5 SP5, ZFD6.5 SP1b. The server policy package is
created and associated with the server. When I try to enter the PXE menu
I get the following error:

Heap:dispose fail
Heap:dispose fail
ERROR: No response from port map service.
Executing DNX imenu.dnx with parameters "defmenu.dat"
Zenworks shutting down....
PXE-MOF Exiting Intel Boot Agent

....any ideas?
