Make sure caps are off.

What is the distro you are using? Are you trying to login as root in GUI? Some distro doesn't allow graphical root login. You'll need to enable graphical root login then.

We are using Redhat linux desktop version 9...

In the same operating system working in some other system....

We are trying to login in GUI mode as a root user...

It shows the error like that....

Press Ctrl+Alt+F1, try login and see what happens.

we are try in command mode also....from ctrl+alt+f1 to ctrl+alt+f6....it's again asking username & password....

red hat 9
you do know that rh9 is WAY past it's end of life
there have been NO security fixes for it in many years - i think the last was in `07 on the extended life support ( 7+ year support contract)

it is very possible the system was cracked and the passwords were changed


try this
reboot but hit a key right before the system starts

edit the boot line in the grub.conf by hitting the "e" key
add a 1 # one to the end of the boot line
hit b to boot

that will put you into single user mode root only
from there you can change the user names and paswords
