Doing it manually... didn't find that option.

Tried it but still the same error.

sanitized (no real reason to but I guess it's common practice)

Oops, I misjudged the situation. It does NOT work if I replace with:

next-server 10.215.144.60;
filename "/BStrap/x86pc/BStap.0";

It gives me the same error message (sorry).

It starts working if I remove the whole class "pxeclient" clause, ie.
I remove next-server, filename and the whole class.

So where is my PXE client picking up the information?
I'm guessing it may be the Altiris PXE server doing some DHCP on its own but
the admin of that system told me that it wasn't.
I'm going to have to check that out.

In any case, my client doesn't seem to like booting
"/BStrap/x86pc/BStap.0" and this may not be the right image to boot.
I'm not an expert in Altiris architecture.
I guess I should be listening to traffic on the Altiris server.

Thanks,

Vieri

Just another pointer: the ALtiris server seems to be configured to detect DHCP
on the LAN and set "option 69".
I'm new to this so I still need to find out how to read "option
69". I'm supposing it's a string or array.

Thanks,

Vieri

This is what I'm seeing on my DHCP server:

So the "filename" for 10.215.144.60 should be correct.

Option 69 is "SMTP server" which really doesn't make any sense...
