I assume said machine does not have an on off button. We have this situation
in the lab at the college; 100 of them. Asign warns people not to do what
you think they should not do. And it mostly works.
Emphasis on "mostly" :-). (I work at the college in question.)
It is especially important in this environment because we have
multi-machine programs running on machines that look like they are just
sitting there.
Quite. Training people not to reboot at the first sign of
trouble has not been 100% effective either. The multi-machine
programs Aaron mentions sometimes need to run for days or weeks to
produce results, so reboots and shutdowns have real consequences.
Eventually the author of these programs found time to add a
checkpointing capability. User training only goes so far, after
all, and mistakes are sometimes made.

I'm hoping someone will come up with an answer to this question.
The "shutdown" menu option (once one is logged in) is particularly
a problem in that it seems all too easy to select accidentally
when one is trying to log out.

I have disabled mine at home on the desktop machine.
I modified my /etc/gdm/custom.conf file
This is older but will point you in the right direction.
It is from this mailing list back in 2005.
http://linux.derkeiler.com/pdf/Mailing-Lists/Fedora/2005-08/1928.pdf
If you look at the /etc/gdm/custom.conf file, it references
/usr/share/gdm/defaults.conf file. Take a look there.
I have not played with this for some time so I cannot remember the full
settings and I am not at home.
