An instance of the OPC COM server is created. The server is launched if it is not already running in the same user. If different applications access the same OPC server then you need to configure DCOM so that all applications launch the OPC server under the same user. Otherwise multiple instances of the OPC server are created.
The OpcEnum server browser is accessed on the remote machine to find the CLSID of the named OPC server.
The Disconnect method needs to be called to release the OPC server before the client program exits.
