今天是週六，上午讀了讀書，下午準備把代碼繼續寫下去。在前一次將一個定製的Name Query廣播發送出去的
那個小程序的基礎上。今天則要將SMB的NetBIOS中Name Service的第一功能：Broadcast Name Registration完成。
總體上將Name Service提供了下面三個功能，
Name Registration/Refresh： The process by which an application adds and maintains a NetBIOS Name to IP address
mapping within an NBT scope.
Name Query： The process of resolving a NetBIOS name to an IP address.
Name Release: The process by which a NetBIOS name to IP address mapping is removed from within an NBT scope.
