For example if the machine belongs to the Fabrikam domain, the default domain for user logon is Fabrikam.
If you enable this policy setting, the a default logon domain will be set to the specified domain which may not be the machine joined domain.
If you disable or do not configure this policy setting, the default logon domain will always be set to the machine joined domain.
