If you have physical access to the hardware, you can always reset the root password. Here are two methods:
1. Boot into "single-user" mode. Typically, when the GRUB menu appears, stop the countdown by hitting the tab key. If in graphical mode, you might need to hit "escape". Edit the kernel line to add the word "single" at the end. then boot--you should wind up in a CLI mode with no password required. Type "passwd root' to change the root password.
2. Boot from any Live CD, mount the Linux partition, and edit /etc/passwd----remove the first "x" in the entry for root. It will wind up like so:
reboot and you will be able to log in as root with no password (at least to a terminal---many distros are set to not allow root to log in to the GUI)
