Local security database is corrupted.
Found reference as:
You might have to change permissions at the SECURITY level of the key."
Used regedt32 end go to the key, can not see anything under SECURITY hive, reseted permission on the key to give administrators full rights - still can not see keys under. Tried to create a key and all keys became visible. So deleted $MACINE.ACC key and was able to unjoin and rejoin the domain.
