Ever wondered what happens when you choose the “Repair” option on your local area network (LAN) or high speed internet connection?

Here is a list of steps that are taken in the order that it happens:

  • 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 (Windows XP SP1 and above)
