If you enable this policy setting computers send dynamic updates to any zone that is authoritative for the resource records that the computer needs to update except the root zone. If you disable this policy setting or if you do not configure this policy setting computers do not send dynamic updates to the root zone or top-level domain zones that are authoritative for the resource records that the computer needs to update.
