The NT_TRANSACT_NOTIFY_CHANGE request is an SMB transaction, not an MS-RPC call. It is carried within an SMB_COM_NT_TRANSACT exchange, and MS-RPC messages are transported over SMB_COM_TRANSACTIONs which are a little bit different. The SMB and MS-RPC mechanisms are quite similar, however, and that may be what Mike means here. Note that any outstanding notification request counts against the MaxMpxCount limit.
