Early comments

The second paragraph is so wrong that it makes my head hurt. How can DCE have something as a close competitor a technology that it incorporates?

I think that if the author tried a wee bit harder the author could maybe praise IBM more, though it'd be difficult. --86.15.128.97 19:42, 25 April 2006 (UTC)[reply]

Microsoft Controversy

I remember reading up into DCE several years ago, I found a lot of accusations on the web that Microsoft "hijacked" a of code from DCE/RPC in "MSRPC" MSRPC is derived from the Open Group's DCE 1.1 reference implementation, but has been copyrighted by Microsoft. None of the UNIX vendors at the time wanted to implement DCE/RPC it at the time, so it was generally considered a non-issue.

Later on, DCOM would be 'donated' by MicroSoft to the Open Group as a marketing stunt. The "D" to COM was due to extensive use of DCE/RPC – more specifically Microsoft's "enhanced" version, known as MSRPC. However, DCOM is pretty worthless without a bunch 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 public, so these technologies have never been available for Unix. Cuvtixo 18:58, 16 August 2007 (UTC)[reply]

Microsoft didn't "hijack" anything. It just decided the OSF royalties were too high, and used the AES to reimplement DCE. Basically, Active Directory is DCE, and still interoperates using the ncacn_ip_tcp protocol. MS has since extended the ncadg_ip_udp stack so that it no longer works with stock DCE. The MS IDL compiler is slightly different, etc.

Needs cleanup

The information about Open Software Foundation clearly needs to go there, and not duplicated here. System V release 4 was an operating system, not a distributed computing environment. Certainly stating unsourced opinions and speculation or personal observation should be removed. Also much overlap with DCE/RPC which is really just the RPC layer. Or perhaps we should merge them? I will work on it as time permits. COI alert: I was part of a group that submitted technology to OSF that was rejected. But I will try to be neutral and state what actually happened with sources if we can find it. W Nowicki (talk) 23:40, 4 April 2011 (UTC)[reply]
