multicast DNS MAC address ...dhcp and tftp servers

I read that your server gets an IP address from the university network?
(I'm thinking the laptop actually is getting an IP address, but instead of you supplying it it's the university's DHCP server that does it. Which, obviously, isn't configured to PXE boot your laptop :e)

While my posting was hard to follow while I struggled with this - and I applaud you for trying -
this was not the case.
If I disconnected from the university system, then booted up by USB or DVD iso,
the dhcp servers were on/in the unix or linux filesystems - and the server was getting IP addresses like 10.0.0.1 . . .

Why are you using multicast to PXE boot a machine?

Try using 'regular' unicast.

The university computer - even though ethernet cable was unplugged and I boot it (either FreeBSD or Fedora live versions with servers) then
with ethernet cable plugged directly into the laptop - was multicasting to a Laser Printer -
it was just configured to do that even after the live version OS boots -
so I guess it made little difference to it that the actual physical MAC address for the laptop is really (now known to be)
Code:
00:40:D0:xxxxxx

The fixes included getting the Intel UNDI, PXE-2.0 (build 082) starting up correctly on the laptop,
with also changing to unicast by the terminal command
Code:
# ip link set dev eth3 multicast off
