The '''Distributed Computing Environment (DCE)''' is a software system developed in the early 1990s by a consortium that included [[Apollo Computer]] (later part of [[Hewlett-Packard]]), [[IBM]], [[Digital Equipment Corporation]], and others. The DCE supplies a framework and toolkit for developing client/server applications. The framework includes a [[remote procedure call]] (RPC) mechanism, a naming (directory) service, an authentication service, and a distributed file system (DFS). DCE RPC was derived from an earlier RPC system called the Network Computing System (NCS) created at Apollo Computer. The naming service was derived from work done at DEC. DCE DFS was based on the [[Andrew file system]] (AFS), originally developed at [[Carnegie-Mellon University]], and later extended by Transarc Corporation (which was later merged into IBM). DCE 1.2.2 was released on 12th January 2005 under a Free Software License (the LGPL) by The Open Group. DCE 1.1 was available much earlier under the OSF BSD license, and resulted in FreeDCE (freedce.sf.net) being available since 2000. FreeDCE contains an implementation of DCOM.
