Specifies if the DNS client may send dynamic updates to zones with a single label name. These zones are also known as top-level domain zones, for example: "com." By default, a DNS client that is configured to perform dynamic DNS update will update the DNS zone that is authoritative for its DNS resource records unless the authoritative zone is a top-level domain or root zone. If you enable this policy setting, the DNS client sends dynamic updates to any zone that is authoritative for the resource records that the DNS client needs to update, except the root zone. If you disable this policy setting, or if you do not configure this policy setting, the DNS client does not send dynamic updates to the root zone or top-level domain zones that are authoritative for the resource records that the DNS client needs to update.
