An example is a publisher who uses two different endpoints (5) to publish data. These endpoints can publish the same category. However, each endpoint requires a different instance number to be considered a distinct publication by the server (2). An instance number is provided by the publishing client.

(2) A specific occurrence of a game running in a game session. A game application process or module may be created more than one time on a single computer system, or on separate computer systems. Each time a game application process or module is created, the occurrence is considered to be a separate instance.

Integrated Windows authentication: A configuration setting that enables negotiation of authentication (2) protocols in Internet Information Services (IIS). Integrated Windows authentication is more secure than Basic authentication, because the user name and password are hashed instead of plaintext.

Interactive Connectivity Establishment (ICE): A methodology that was established by the Internet Engineering Task Force (IETF) to facilitate the traversal of network address translation (NAT) by media.

interactive report: A visualization that has a presentation mode that provides sort, filter, and pivot capabilities for displaying different views of the data. The underlying data can be stored either in the workbook or in an external data source.

interface: (1) A specification in a Component Object Model (COM) server that describes how to access the methods of a class. For more information, see [MS-DCOM].

(2) A group of related function prototypes in a specific order, analogous to a C++ virtual interface. Multiple objects, of different object class, may implement the same interface. A derived interface may be created by adding methods after the end of an existing interface. In the Distributed Component Object Model (DCOM), all interfaces initially derive from IUnknown.

(3) This term is used exactly as specified in [C706] section "Introduction to the RPC API" in Part 2.

(4) A collection of messages used together. Interfaces support inheritance and extensibility through the Interface Query message as defined in [MS-RDPEXPS] section

(5) Represents a network that can be reached over an adapter. Each interface has a unique interface identifier also known as an interface index. interfaces that are active have an adapter that is providing connectivity to the network they represent. interfaces that are inactive do not have an adapter providing connectivity unless an administrator disabled the interface after it already had an adapter. Routing a packet to a network represented by an interface will cause the router to allocate an adapter for that interface, and will establish a wide area network (WAN) connection to the remote network. Allocating an adapter to an interface is referred to as binding. In the case of a local area network (LAN) interface, the interface corresponds to an actual physical device in the computer, a LAN adapter. In the case of a WAN interface, the interface is mapped to a port at the time that a connection is established. The port could be a COM port, a parallel port, or a virtual port (for tunnels such as PPTP[RFC2637] and L2TP[RFC2661]). WAN interfaces have the additional quality that they typically receive a network address only at the time that a connection is established. For example, a WAN interface using PPP [RFC1661] receives its network layer address from the remote peer during the connection process. Receiving a network address as part of the connection process is sometimes referred to as late-binding.

Interface Definition Language (IDL): The International Standards Organization (ISO) standard language for specifying the interface for remote procedure calls. For more information, see [C706] section 4.

intermediate NAT: A network address translation (NAT) address that is present in the communication path of two endpoints (5).

IIS version 5.0 shipped as part of Windows 2000, IIS version 5.1 as part of Windows XP, IIS version 6.0 as part of Windows Server 2003, and IIS version 7.0 as part of Windows Vista and Windows Server 2008.

IPsec supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. The Microsoft implementation of IPsec is based on standards developed by the Internet Engineering Task Force (IETF) IPsec working group.

Internet protocol server: A software program that implements the server host of a standard Internet protocol such as HTTP or FTP.

Internet Protocol version 4 (IPv4): An Internet protocol that has 32-bit source and destination addresses. IPv4 is the predecessor of IPv6.
