A.If you right-click a network connection and select Status, Windows displays information about the connection's speed, duration of connection, and packet activity. For XP and later, a Repair option appears on the Support tab. When you click Repair, Windows attempts to resolve a range of problems. Specifically, the OS
Attempts to renew the DHCP lease, if the connection obtains its IP address through DHCP, using a broadcast message.

问:如果你右键点击了一个网络连接并选择了"状态",Windows显示了一个包括以下信息的对话框:连接速度、连接持续时间以及数据包的活动状态(接收/发送数量)。XP以上的操作系统版本中,微软在状态属性中新加入了一个"修复"的选项在Support Tab中,当你点击了"修复",Windows将会尝试修复你的网络连接。特别地说,操作系统按照以下步骤执行(实际上是调用内部的函数实现,本文只是模拟一个类似的命令行流程):
1、如果此连接通过广播方式从DHCP获得了一个IP地址的话,修复过程首先会尝试更新DHCP租用。
2、刷新ARP缓存(arp -d *)
3、刷新NetBIOS缓存(nbtstat -R)
4、刷新DNS缓存(ipconfig /flushdns)
5、重新在WINS上注册NetBIOS名称和IP地址(nbtstat -RR)
6、重新在DNS上注册计算机名称和IP地址(ipconfig /registerdns)
