6 Appendix A: Product Behavior
The information in this specification is applicable to the following Microsoft products or supplemental software. References to product versions include released service packs.
Note: Some of the information in this section is subject to change because it applies to a preliminary product version, and thus may differ from the final version of the software when released. All behavior notes that pertain to the preliminary product version contain specific references to it as an aid to the reader.

Exceptions, if any, are noted below. If a service pack or Quick Fix Engineering (QFE) number appears with the product version, behavior changed in that service pack or QFE. The new behavior also applies to subsequent service packs of the product unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.
Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms SHOULD or SHOULD NOT implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term MAY implies that the product does not follow the prescription.
<1> Section 184.108.40.206: In the Windows implementation of the DNS server, the DNS client will find that the DNS server signed a DNS update response, as described in [RFC3645], only if the RCODE value in the response message is zero (indicating success).
If the RCODE value in the DNS update response message is not zero (indicating failure), the DNS client will find that the DNS server did not sign the response. Instead, the DNS server copied the DNS update request message, changed the RCODE value to the applicable nonzero error value, and sent that message back to the DNS client as the response. The message was otherwise unmodified; that is, the response message contains the same signature that was in the request message.
