I believe that ESX is a derivative of Red Hat.  You will have to reboot the ESX host, and at the grub bootloader, press Tab.  This should allow you to enter in boot parameters to the kernel.  Type in "linux 1" and it should boot into a root shell, where you can reset the root password by using "passwd root".  Then restart again and you should be all set.

Good luck,
