 Hard reboot (ie pull the plug), then boot into single user mode. This
isn't pretty, but it works. Then reset the root password, and reboot.

 What I would do is save the passwd file as something else (like
passwd.foo) so that you can keep your users' names and UIDs if you need
to. Then remove all entries from /etc/shadow and /etc/passwd and recreate
their accounts.  After that you can either chown their directores or
change the UIDs to match what they used to be. If you didn't do anything
fancy with groups/etc then you should be ok, but time consuming depending
on the number of clients you have. You'll have to tell your users that
you've reset their passwords and that they should contact you.

Good luck!

Cheers,

Chris
