If your server doesn't boot after modifying lts.conf you have some much
bigger issues than you currently think. lts.conf is only used for
booting clients, your server doesn't read it at boot. Changes in the
file should never affect server boot.
Perhaps you have installed the ltsp-client package on your server
alongside the ltsp-server package? If so, then that's your problem.

Thanks Rob,
Here is what lts.conf says
[default]
LDM_THEME=edubuntu
LANG=en_US.UTF-8
LANGUAGE=en_US.UTF-8
LDM_LANGUAGE=en_US.UTF-8
I added to it
XSERVER = vesa
X_MODE_0 = 1280x1024
but that was a no-no (the server wouldn't boot afterwards). As I am
reinstalling Edubuntu for yet another time I'll mention what may be
another symptom/cause. When installing we are given the option to
download updates as we install. Updating seems to cause edubuntu to
not be able to access the Internet afterwards (not positive but sure
seems like it).

Clients should auto-detect their graphics hardware and load the
appropriate drivers. Yours seem to not be doing that. Perhaps
you have
an outdated version of Edubuntu (or a too-new version that has bugs).
Or maybe you're just unlucky. Either way, you can manually
specify the
drivers and resolution in lts.conf.
I think Edubuntu keeps that file in /var/lib/tftpboot, but I'm not
sure.
I also think you need to run another command after editing lts.conf
(this is related to Edubuntu using a squashed image instead of
NFS, like
my Debian system). Somebody on this list is sure to know what that
command is -- I can't remember it.
Anyway, you'll want to run 'man lts.conf' to get some details on how
that file is structured. You'll probably want to include
something like
this for your problem clients:
XSERVER = vesa
X_MODE_0 = 1280x1024
vesa is a good xserver value to start with, because it usually
works. It is
slower than others, so once you get things working you may want to try
other values. You can specify these settings as default or per-client
(by MAC address or by hostname, I believe).
