	TDG - a technical introduction to DCOM (Site not responding. Last check: 2007-11-03)
		Components in a distributed application need to be notified if a client is not active anymore, even—or especially—in the case of a network or hardware failure.
		DCOM provides a multitude of ways to "tweak" the actual network protocol and network traffic without changing the way that clients perceive the component: Client-side caching, referrals, and replacing the network transport when necessary are but a few techniques that are possible.
		DCOM on the component's machine then validates the username again using whatever authentication mechanism is configured and checks the access control list for the component (actually for the first component run in the process containing the component).

	The DCOM (Distributed Component Object Model) and CORBA (Common Object Request Broker Architecture) technologies are ...
		DCOM is a set of Microsoft concepts and program interfaces in which client program objects and server program objects can request services from server program objects on other computers in a network.
		Distributed objects can be implemented in one language and used by client applications implemented in a different language.
		Object handles that are used to reference distributed object instances within the context of a client’s programming language or script.

	What is DCOM? - a definition from Whatis.com - see also: Distributed Component Object Model
		DCOM (Distributed Component Object Model) is a set of Microsoft concepts and program interfaces in which client program objects can request services from server program objects on other computers in a network.
		DCOM is based on the Component Object Model (COM), which provides a set of interfaces allowing clients and servers to communicate within the same computer (that is running Windows 95 or a later version).
		DCOM is generally equivalent to the Common Object Request Broker Architecture (CORBA) in terms of providing a set of distributed services.

	[No title]
		Object RPC specifies: @ How calls are made on an object @ How object references are represented, communicated, and maintained 1.1 Purpose There is a natural tendency in a networked environment to create entirely new application-level protocols as each new or seemingly unique combination of client, user agent, and server requirement arises.
		Objects which are not pinged in fact need not be reference counted either, though it is legal (but pointless) for a client to reference count the IPIDs of such objects.
		For all other objects, assuming a non-zero ping period, it is the responsibility of the holder of an interface reference on some object to ensure that pings reach the server frequently enough to prevent expiration of the object.

	Technical Introduction To DCOM (Site not responding. Last check: 2007-11-03)
		Components in a distributed application need to be notified if a client is not active anymore, even-or especially-in the case of a network or hardware failure.
		In the conventional approach, either clients and components have to be updated simultaneously or the old component has to be retained until all clients have upgraded-an undertaking that can become a major administrative burden when a significant number of geographically dispersed sites or users is involved.
		Components can require different levels of encryption and different levels of authentication, while clients can prevent components form using their credentials when impersonating.

	Component Object Model (COM)
		Distributed computing is becoming a mainstream due to the advance in high-speed networking and the explosive growth of the Internet.
		Distributed objects combine the two trends and are becoming increasingly popular.
		The argument is that, by using COM/DCOM as a platform for building distributed object applications, researchers and developers can concentrate on important issues specific to their applications without having to devote a significant portion of their efforts to building the supporting infrastructure.

	COM (Component Object Model) (Linktionary term)
		COM (Component Object Model) is a Microsoft specification that defines the interaction between components in the Windows environment.
		DCOM (Distributed Component Object Model) is the network version of COM that allows objects running in different computers attached to a network to interact.
		This topic continues in "The Encyclopedia of Networking and Telecommunications" with a discussion of DCOM (Distributed Component Object Model).

	Distributed component object model - Wikipedia, the free encyclopedia
		Distributed Component Object Model (DCOM) is a Microsoft proprietary technology for software components distributed across several networked computers to communicate with each other.
		DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure.
		One of the key factors in solving these problems is the use of DCE/RPC as the underlying RPC mechanism behind DCOM.

	Network Computing (Site not responding. Last check: 2007-11-03)
		Distributed object technology is, without a doubt, the shape of middleware in the days to come.
		It provides the communications bus that enables plug-and-play interoperation of distributed components across diverse networks and operating systems, allowing them to be easily assembled, reused and managed.
		Unlike simple service daemons, distributed components require numerous options, such as invocation policy and threading model to be configured for defining the operating environment.

		DCOM has been submitted to the IETF as a draft standard.
		DCOM serves the same purpose as IBM's DSOM protocol.
		DCOM is broken because it's an object model that has no provisions for inheritance, one of the major reasons for object oriented programming in the first place.

	COM & DCOM: Component Object Model and Distributed Component Object Model
		Component Object Model (COM) refers to both a specification and implementation developed by Microsoft Corporation which provides a framework for integrating components.
		This framework supports interoperability and reusabilityof distributed objects by allowing developers to build systems by assembling reusable components from different vendors which communicate via COM.
		DCOM allows COM objects executing on one computer to create COM objects on other computers and access their methods.

	Distributed Communication Utility Page
		DCOM protocol provides communication among software modules directly across a network given a secure, consistent and efficient procedure.
		DCOM uses Internet protocols as HTTP, based upon the Open Software Foundations's DCE-RPC specification, appropriate to both Java applets and ActiveX given the Component Object Model(COM).
		Quote from their white paper however indicates their solution may not be a DCOM solution with portability across all platforms, "...providing native COM, CORBA and RPC integration using an industry standard transport protocol." A truely portable solution would not consist of native code, specific to the system.

	Component Object Model - a definition from Whatis.com
		Component Object Model (COM) is Microsoft's framework for developing and supporting program component objects.
		It is aimed at providing similar capabilities to those defined in the Common Object Request Broker Architecture (CORBA), a framework for the interoperation of distributed objects in a network that is supported by other major companies in the computer industry.
		COM includes COM+, Distributed Component Object Model (DCOM), and ActiveX interfaces and programming tools.
