sudo and all admin accounts disabled?

we have the latest ubuntu installed. everything was working
fine. all  
of a sudden, we have no superuser access. all admin accounts
that  
were previously working fine now have no ability to run sudo
or sudo - 
s with the error that these usernames are not in the sudoers
file.  
However, I know they were all admin accounts when they were
setup. I  
know this is not simply someone taking away my privileges
because I  
setup all admin accounts and have checked each one and they
are all  
not allowed to do a sudo or a sudo -s.

do i need to do a reinstall? Please advise.

thanks,
Jordan

No, though should be recoverable. As Schalken said, you'll
need to boot
to recovery mode. If you don't see that selection a few
moments after
you turn on your computer, you should at least see a line
that says
"Press ESC for boot menu". Press escape and
you'll see the menu. There
should be at least one entry that has (recovery mode)
mentioned. Select
that entry and press return. In a few moments, you'll have
a root prompt
from which you can manually edit /etc/sudoers, say with the
nano
program:
# EDITOR=nano sudo visudo
double check that you have this line in the file:
%admin  ALL=(ALL) ALL

If it's there, already, you may want to simply add your
user account on
a new line, for example:
burner ALL=(ALL) ALL

Thank you to everyone in this thread. It works flawlessly
now, no  
reinstall required. Just thought I'd write back to tie up
loose ends.  
Thanks again!
