Root Password Can't change


I am really new to Linux, in my new job place we have Signage display device running with Debian 5 and its not working at all. I try to reset the root password but its give me an error:



Passwd:user not known to the underlying authentication module.


Also I noticed that in the grub these details are mentioned:



kernel /boot/vmlinuz-2.6.26-2-686 root=/dev/sda1 ro single acpi=off


What do I need to do to change the password?
