I have a Linux server at ip address running DHCP, TFTP and syslinux.

DHCP config contains the following:

filename "/pxe/syslinux/pxelinux.0";

and the 'default' pxelinux.cfg contains:

LABEL altiris
    MENU LABEL ^7. Altiris
    COM32 pxechn.c32

When a PXE client boots in my network it loads the menu from
However, when the user selects menu item 7 the following message is displayed right after the "greeting message" from the second PXE server at

PXEPreZero: Invalid PXE Server list format

Note that the server at is running a proprietary PXE software (Altiris).

Any ideas?
How can I debug this?

As a test, I modified my DHCP server at and replaced the following line:
(without specifying 'filename')
and the PXE client seems to boot the Altiris menu correctly.

So I don't know what I'm missing.
