1) You have tried several times I hope?
If not, just try again - maybe ther was a mismatch between your two passwords.
2) How about password requirements?
AFAIK that is most commonly set with PAM.
Check under /etc/pam.d/ (or whatever GUI-tool there might be for this).
3) Are all accounts local, or do you use an authentication system (AD, LDAP etc)?

Is the root filesystem mounted in read only mode by any chance?
