As per vmware documnetaion

Reinstalling the ESXi host is the only supported way to reset a password on ESXi. Any other method may lead to a host failure or an unsupported configuration due to the complex nature of the ESXi architecture.

Now if you can take the risk then check ESXi - Reset the password for root . This use a Slax Linux Live CD to reset the password.
