I have a very annoying issue where a desktop lost trust with the domain. As a standard practice I joined it to a workgroup and rebooted. When I tried to join it back to the domain, it gave me the following error "Unable to load the specified registry hive". One of the common posted solutions is to go into the GPEditor and add the admin to the \computer configuration\Windows Settings\ Security Settings\ Local Policies\ and filed the Backup and Restore files and directories. When I locate these the ADD button is greyed out. I have reset the group policies to NOT Configured and ran GPUPDATE /force and rebooted.
None of this has made a difference and I am unable to join the domain.
Is there a way to repair the registry hive and get this system back on the domain without completely rebuilding the desktop?
