Repair Option on a Local Area Network or High-Speed Internet Connection
In the latest versions of Windows, you are given a repair option when you right-click a network connection in the Network Connections window. Below, you will find exactly what Windows does, in order, when you tell it to repair a network connection:
Dynamic Host Configuration Protocol (DHCP) lease is renewed (ipconfig /renew)
Address Resolution Protocol (ARP) cache is flushed (arp -d *)
Reload of the NetBIOS name cache (nbtstat -R)
NetBIOS name update is sent (nbtstat -RR)
Domain Name System (DNS) cache is flushed (ipconfig /flushdns)
DNS name registration (ipconfig /registerdns)
IEEE 802.1X Authentication Restart (WinXP SP1 or later)
Note: The bit in parenthesis is the actual command that is issued, which you can perform yourself from a command prompt.
