Ошибка ОРС сервера!!! Как исправить???

вот фрагмент кода:


        public void Connect(string clsidOPCserver)
        {
            Disconnect();
            Type typeofOPCserver = Type.GetTypeFromProgID(clsidOPCserver);
            if (typeofOPCserver == null)

               Marshal.ThrowExceptionForHR(HRESULTS.OPC_E_NOTFOUND);
              
                    OPCserverObj = Activator.CreateInstance( typeofOPCserver );
            ifServer = (IOPCServer)OPCserverObj;
            if (ifServer == null)
               Marshal.ThrowExceptionForHR(HRESULTS.CONNECT_E_NOCONNECTION);

            // connect all interfaces
            ifCommon = (IOPCCommon)OPCserverObj;
            ifBrowse = (IOPCBrowseServerAddressSpace)ifServer;
            ifItmProps = (IOPCItemProperties)ifServer;
            cpointcontainer = (UCOMIConnectionPointContainer)OPCserverObj;
            AdviseIOPCShutdown();
        }



на   Marshal.ThrowExceptionForHR(HRESULTS.OPC_E_NOTFOUND); вываливается и возвращает 0xC0040011

ЧТО ДЕЛАТЬ???
