Repair feature

As an alternative to ipconfig you can use Repair to renew LAN or high-speed Internet connection IP settings. Repair performs a series of commands that repair a connection. The commands that are invoked by Repair are listed below with their command-line equivalents:

Repair	Command-line equivalent
Checks whether DHCP is enabled and, if enabled, issues a broadcast renew to refresh the IP address	No command line equivalent available
Flushes the ARP cache	arp -d *
Flush the NetBIOS cache	nbtstat -R
Flushes the DNS cache	ipconfig /flushdns
Re-registers with WINS	nbtstat -RR
Re-registers with DNS	ipconfig /registerdns

Important

•	Repair uses a broadcast renew and will cause a computer to accept any lease from any DHCP server that is on the network. In contrast, a unicast renew (ipconfig /renew) will only renew the existing lease from the last DHCP server from which the client got a lease.
