The Domain Name System (DNS) is responsible for translating host names to IP addresses (and vice versa) and is critical for the normal operation of internet-connected systems. DNS cache poisoning (sometimes referred to as cache pollution) is an attack technique that allows an attacker to introduce forged DNS information into the cache of a caching nameserver. DNS cache poisoning is not a new concept; in fact, there are published articles that describe a number of inherent deficiencies in the DNS protocol and defects in common DNS implementations that facilitate DNS cache poisoning.

If you experience a network connection problem. Here are some of the most useful network troubleshooting commands. Just type the command in a Command Prompt Window (CMD.EXE).
# ipconfig /all [ Display full Information about Network configuration]
# ipconfig /displaydns [ Displays the contents of the DNS client resolver cache ]
# ipconfig /flushdns [ Clear the local dns cache.]
# ipconfig /registerdns [ Is used for manual dynamic registration for the DNS names and IP addresses that are configured at a computer.]
# ipconfig /release [ Sends a DHCP release message to the DHCP server to release the current DHCP configuration and discard the IP address configuration for all network adapters.]
# ipconfig /renew [ Renews DHCP configuration for all network adaptors. *It does not clear the client resolver cache on client computers.]
Another excellent command is Netsh – Netsh.exe is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running.
# netsh interface ip set dns [ is used to configure the source of DNS server addresses, set a DNS server address, and manage DNS registration behavior. And not to clear client resolver caches.]
# netsh interface ip set address “Local Area Connection” dhcp [ Typing this command changes the interface named “Local Area Connection” to DHCP configuration.]
