forgot the root password to esx3.5 but my VC has it cached and it is working fine. Is there any way to change the password without rebooting the esx?
There's no way without a reboot. Two in fact. So if you've got ESX is in a cluster, VMotion your VMs off the ESX server onto another, and reboot it.
At the first menu type "a", then
at the prompt type "single", then
at the prompt type "passwd" and enter, then
type in your new password and then enter. then
type "reboot".
