1. A distributed system including a plurality of computer systems coupled together through a common communication network, a first one of said computer systems corresponding to a non distributed computing environment (DCE) computer system which includes a first type of operating system for running non DCE application programs on said first one of said computer systems and a second one of said systems corresponding to a DCE system including a second type of operating system which is compatible with said DCE system for running application programs compiled on said second system and wherein said distributed system further includes: an ally component and a distributed computing environment (DCE) application system installed in said second system to run in conjunction with said second type of operating system, said DCE application system including a plurality of basic distributed services and a remote procedure call (RPC) component for processing remote procedure calls between client and server application programs communicating through a pair of RPC stub components according to a predetermined RPC protocol, said ally component including a plurality of management routines for enabling local requests made by said client application programs running on said first system to be processed by accessing said plurality of distributed service components of said DCE system; and, an RPC runtime component included in said first computer system, said RPC runtime component including a RPC subcomponent and an application program interface (API) subcomponent operatively coupled to each other, said RPC subcomponent including a minimum number of ported routines responsive to a corresponding number of standard DCE RPC requests for determining when any local client request is to be forwarded to said ally component of said second computer system and said API subcomponent including a plurality of subroutines for enabling transfer of said each local client request received from said RPC subcomponent of said RPC component of said first computer system to said ally component of said second computer system using said predetermined RPC protocol established by said client and server RPC stubs for accessing a designated one of said distributed service components of said DCE application system of said second computer system thereby eliminating the need of having to port said DCE service components to operate on said first computer system.
