While the OPC standard is useful in this application, OPC and DCOM together can pose challenges to implement and maintain.
This document, enumerates the DCOM challenges, presents the most suitable replacement technology, compares Dot Net Remoting technology with DCOM, overviews a flexible architecture with Dot Net Remoting, and offers a solution that addresses the security issues with the proposed architecture.
