This is a DCOM Security error. Typically this error occures when the proper DCOM permissions have not been applied to the server for Access and Launch. DCOM will tell the server if a request from a client appli8cation is coming from an allowed user. Likewise, a response from the server is validated int he same way. If DCOM informs either the server or client applications that a user is not authorized then the connection fails as denied.
Look at the documentation provided with the OPC server for recomdantions on DCOM Security settnigs.
