Q: If you right-click on a network connection and select Status, Windows displays a dialog box that includes the following information: Connection speed, duration of connection, and the active status of the packet (receive/send quantity). In the OS version above XP, Microsoft has added a "fix" option to the Status attribute in Support tab, and when you click "Fix", Windows will try to repair your network connection. In particular, the operating system performs the following steps (in effect invoking the internal function implementation, which is simply simulating a similar command-line process):

1. If this connection obtains an IP address from DHCP by broadcasting, the repair process first attempts to update the DHCP lease.

2, flush ARP cache (arp-d *)

6, re-register the computer name and IP address on DNS (IPCONFIG/REGISTERDNS)
