Evening lads,
I seem to be in a bit of a mess trying to get an opc connection to work out between two servers.
I was getting the "Access Denied" error but after a few hours of DCOM Security reading I managed to get through that.
However, now, whenever I try to connect I run into the following error:
COM/OPC error 0x80040154 on CoCreateInstanceEx()
Error string: Class not registered
I am using Matrikon's OPC Explorer as a client (run with the same user as the one running the opc server). And on the other side there is an Emerson DeltaV OPC Server.
Where is it not registered? On the Client server?
I am not very familiar with the concept of (D)COM, but I do know I have to register its interfaces (or classids) on the com components console. Moreover, I am completely unfamiliar with DeltaV system, so I would not know whether there is some com component I have to explicitly register on the client...
Cheers!
