tdi connect 的问题

打开了地址对象和文件对象，建立了association，在connect时总是返回STATUS_INVALID_ADDRESS_COMPONENT不知道是怎么回事
。。。
pConnectInfo->RemoteAddressLength = sizeof ( TA_IP_ADDRESS );
pConnectInfo->RemoteAddress = (PUCHAR)pConnectInfo +
                           sizeof( TDI_CONNECTION_INFORMATION );
pConnectInfo->UserDataLength = 0;
pConnectInfo->UserData      =NULL;
pConnectInfo->OptionsLength  =0;
pConnectInfo->Options       =NULL;
pAddress = (PTA_IP_ADDRESS)(pConnectInfo->RemoteAddress);
pAddress->TAAddressCount = 1;
pAddress->Address[0].AddressLength = sizeof ( TDI_ADDRESS_IP );
pAddress->Address[0].AddressType = TDI_ADDRESS_TYPE_IP;
pIp = (PTDI_ADDRESS_IP)(pAddress->Address[0].Address);
pIp->sin_port = W_LITTLE_TO_BIG_ENDIAN(MY_PORT);
pIp->in_addr =D_LITTLE_TO_BIG_ENDIAN(0L);  
。。。
TdiBuildConnect (
                 pIrp,
                 pDeviceObject,
                 pObject,
                 NULL,
                 NULL,
                 NULL,
                 pConnectInfo,
                 ReturnConnectionInfo );
dStatus = TdiCall ( pIrp, pDeviceObject, &IoStatusBlock );
