Exceptions, if any, are noted in this section. If an update version, service pack or Knowledge Base (KB) number appears with a product name, the behavior changed in that update. The new behavior also applies to subsequent updates 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 3.1.4:  Windows Vista operating system, Windows Server 2008 operating system, Windows 7 operating system, Windows Server 2008 R2 operating system, and Windows Server 2012 operating system: Specify target level 6.0. Windows 2000 operating system, Windows XP operating system, and Windows Server 2003 operating system: Specify target level 5.0.

<2> Section 3.1.4.1: The Exchange 2003 and Exchange 2007 implementation of this protocol follow these NSPI server preference rules:

  1. Server is up and functioning.

  2. Server supports the client's protocol sequence.

  3. Server has a writeable copy of the object represented by pUserDN.

  4. Server is physically close to the NSPI referral server.

The NSPI servers are compared on these four properties in the order above. If two servers both satisfy or both do not satisfy 1, then 2 is used as a tie-breaker; if two servers both satisfy or both do not satisfy 1 and both satisfy or both don't satisfy 2, then 3 is used as a tie-breaker; and so on. The server that breaks the tie by satisfying a property that the other one does not satisfy is the preferred server. If multiple servers tie after comparing all four properties, those servers are returned in "round robin" order, meaning that each call to RfrGetNewDSA will return the next server in the list of tied servers. In the Exchange 2003 and Exchange 2007 implementation of this protocol, the administrator can configure the protocol to reverse the priorities of properties 3 and 4.

<3> Section 3.1.4.2: In Exchange 2003 and Exchange 2007, the CN=" instance-name " element is not supported.
