Lost ESX-server's root password ?!?!! :-(

After a little google-ing I found a Red Hat Enterprise password reset procedure, that also works on ESX 3, actually it's quite easy.

1. Reboot your ESX-server.
2. In the Linux GRUB menu select "Service Console" and press "e" to edit.
3. Go to the line that starts with "kernel" and press "e" again
4. Append the word "single" at the end of the line and press enter
5. Press "b" to boot with these options
6. Once the system is booted you get a Linux command prompt, where you can enter "passwd" to change the password
7. Reboot and login using your new password
