hii atee,
some linux distributions like fedora, ubuntu, red hat doesn't provide to login as a root user.
if you want to perform administrative tasks you need to run as root by using "su" command. Some distributios like SUSE provides to login as root. so you are not able to login as root !

so I've got no choice But to format the system.

DO you want to format the system ?? You have to remember one thing, some enterprise editions doen't allow to run new softwares until registered.

RH9 is old distro,but you should've been prompted for entering the root password during installation,so when you're in the terminal type su - and enter password,you want see what you type but when you're done press enter.Now you're root.Then you can use command;
to specifie the maximum number of days the password is valid,so in this example the password will be valid for 30 days for the user that you have to specifie.
You can folow this guide to change the root password.

And better still install a recent distro like Fedora 10 or Ubuntu-8.10 or the LTS version (for long term support)

First, by default, an user's password is set to "expire" after first use by the user. That allows the administrator to create the user's account with a known password, but forces the user to change the password after they first use the password. This works well if the user logs on via a console connection, since the message that the password need to be reset is displayed there, with, IIRC, the requirement to make the change before proceeding. I suspect that the older GUI interface you're using may not handle this so gracefully, leaving you with an expired password and no message that the password had expired so you didn't know to change it.

One approach to solving the problem is to boot the system in maintenance mode, log on as "root" and reset the user's password. Then log on as the user, and re-set the password to whatever will work. (There are "rules" for "good" passwords that are enforced when a password is changed.)

To log on in "maintenance" mode (assuming you know the "root" password), just press the <Escape> key as soon as the GRUB boot splash screen is displayed (before the system starts to boot), and follow the on-screen instructions to edit the line that starts with kernel to have a " 3" (no quotes, of course) at the end of the the line, and then boot from the altered commands. (Note: Changes made to the GRUB boot instructions in this way are only temporary.)

Thanx guys it really works but as i 've created new user at shell prompt set its name and password but still its no accepting on GRUB login screen.

Even i have change the expiry date duration by the command chage -M 30 username it showed the message at login screen "no authentication"

wats going on ...?

Then this is a PAM issue.I don't know where on RH9 PAM is,but you can search for something like /etc/pam.d or /etc/pam.conf and change the configuration file.If you try to do so keep this in mind;

"Samba" is a new topic, so you should start a new thread on that issue. In any case, please read the samba tutorial so you know what you're talking about before posting.
