For a more in depth look at DCOM Configuration please refer to DCOM Background.
This is intended to be a general DCOM configuration tutorial for various Windows operating systems. Your particular settings may vary depending on whose OPC Server/Client you are running and how you intend to run your system. Software Toolbox is able to provide extensive assistance with settings for OPC Servers that are purchased from us. We are also able to provide limited assistance with OPC Servers that are not bought from us, provided you are using one of our client applications. If you are not using any of our products, then we are not able to provide free technical assistance.
