Deletes all information for the specified realm from the registry. For examples of how this command can be used, see Examples.
The realm name is stored in two places in the registry: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001 and \CurrentControlSet\Control\Lsa\Kerberos.
You cannot remove the default realm name from the domain controller because this will reset its DNS information, and removing it might make the domain controller unusable.
