Per vmware... you can't. You have to re-install ESXi on the host. Attempting to do anything else is unsupported and may break things.

You can re-install ESXi and then re-import all your VMs into the inventory. Any other configuration (e.g. networking, resource allocation, user accounts and access controls) need to be re-done.

or, you can follow this article here, unsupported but works very well.

http://www.vm-help.com/esx/esx3i/Reset_root_password.php

and works for ESXi 3.0 all the up to the current latest ESXi 5.5 U2.

and the only thing that this method "breaks" is the password for root!

That must have been an upgrade ?

Did you do a full install ?

I have a question, as i just joined EE recently.

Somehow, our ESXI root password is lost or changed. I do not have a backup of this server, so i have some rudimentary questions.

1. If we reinstall esxi, what happens to all the existing live VMS. I am assuming they will all go down during that period, but is there a way quickly bringing them back online on the same hardware.

I have seen it mentioned in some articles but i have no expertise in this area, and need to understand what my options might be.

thanks
