History
DCE/RPC was commissioned by the Open Software Foundation in a "Request for Technology". Apollo Computer brought in NCA - "Network Computing Architecture" which became Network Computing System (NCS) and then a major part of DCE/RPC itself. The naming convention for transports that can be designed (as architectural plugins) and then made available to DCE/RPC echoes these origins, e.g. ncacn_np (SMB Named Pipes transport); ncacn_tcp (DCE/RPC over TCP/IP) and ncacn_http to name a small number.
MSRPC is a Microsoft proprietary technology also derived from the Distributed Computing Environment 1.1 reference implementation, but has been copyrighted by Microsoft. MSRPC is featured in Microsoft's Distributed Component Object Model (DCOM), a proprietary technology for software components distributed across several networked computers to communicate with each other. The addition of the "D" to COM was due to extensive use of DCE/RPC. DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure. It has been deprecated in favor of Microsoft .NET. DCOM would be "donated" by Microsoft to the Open Group, an industry consortium to set vendor- and technology-neutral open standards for computing infrastructure. It was formed when X/Open merged with the Open Software Foundation in 1996. However, DCOM comes without several of application-level class libraries, such as ODBC, OLE DB, ADO, and ASP to run on top of it. Microsoft never released these specifications to the Open Group or the public.

Famous quotes containing the word history:
“The thing that struck me forcefully was the feeling of great age about the place. Standing on that old parade ground, which is now a cricket field, I could feel the dead generations crowding me. Here was the oldest settlement of freedmen in the Western world, no doubt. Men who had thrown off the bands of slavery by their own courage and ingenuity. The courage and daring of the Maroons strike like a purple beam across the history of Jamaica.”
—Zora Neale Hurston (1891–1960)
“It’s not the sentiments of men which make history but their actions.”
—Norman Mailer (b. 1923)
“I believe that history might be, and ought to be, taught in a new fashion so as to make the meaning of it as a process of evolution intelligible to the young.”
—Thomas Henry Huxley (1825–95)
