Do you have a tutorial for configuring DCOM in such a way that will allow my OPC Servers/Clients to communicate both locally and/or across the network?

To be able to access an OPC server remotely over a network from a client running on a different machine, there are three major pre-requisites:

1. The OPC server is properly installed on the machine where it will reside. The checkpoint here is "can you see the OPC server from an OPC client running LOCALLY on the same machine as the OPC server." If the answer is yes then the OPC server is installed OK.
   
2. The machine where the OPC server is installed must be properly configured for DCOM in terms of registry settings and security settings.
   
3. The remote client machine must be properly configured for DCOM in terms of registry settings and security settings. Items (2) and (3) have little to nothing to do with the OPC server vendor's product but are merely the nature of Microsoft DCOM.
