One of the best (and easiest) ways to recover the root password when you have physical access to the server is to boot from a different disk or partition and then mount the disk or partition with the lost root password file and edit the password file. Normally, just make the password entry blank.

Another way is to boot from a different disk or partition and then mount the disk or partition with the lost root password file and edit the password file and change the userid to "0" of a user whom you know the root password. This will give you root access to that "other user" and you can then change the password of root with that user (since their userid is 0).

Then reboot with the original disk and clean up any changes you made, change passwords, etc.

Always remember, if you have physical access to a computer / disk and loose any passwords, you can mount the disk (where the lost password file resides) and edit it on another computer, assuming of course you have root access on the secondary computer and the disk does not have special access controls in place (most do not).
