We are trying to set up DCOM so our client can talk to an OPC server located on another machine in our organization's domain. The error we are running into is:

Unable to cast COM object of type 'System.__ComObject' to interface type 'OPC.IOPCServerList'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{13486D50-4821-11D2-A494-3CB306C10000}' failed due to the following error: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Does anyone know what could be causing this error?

Thanks
