I am using VMware ESXi 4.1 for running my virtual machines. Once i accidentally set "no access" permissions for user "root" over vSphere interface. AS root is my only account, i `ve lost everything, even SSH and Local Tech Support rejects root credentials. Only i have is acces to the System customization menu. If any way to restore root user permissions?
According to this a VMware KB Article the only solution for ESXi is to reinstall. I believe that you an do a repair reinstall that leaves the VMs unaffected. You may need to re add the VMs to the inventory and setup the virtual networking though.
