I am using Red hat 9.0.Tomorrow I was (sunday) using XCHAT as root. When I login next time, as Root or my one user account. It gives message "Authentication Failed". But when I login with non existing accounts then it simply blank the text area for another user name entry.
This way my system is useless. It do not want to format my system. Because there is very important data. So tell tell me the right way to access my system.
