I'm trying to make an OPC connection to a Kepware OPC server using the simple OPC example provided by Kepware, or by my own code. Either way, and I call the CONNECT method, it just returns an error 430. I've gone through all of the DCOM configuration that I can find, but no luck. Can anyone point me in the right direction? This is on a Windows XP SP2 box, trying to connect to the local OPC server.
