Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).
Tips:
If it is not necessary to view the current IP addresses on a computer, simply type 'ipconfig /release' or 'ipconfig /renew' (without the quotes) in the text box that appears in Step 3.
To bring a computer back onto the network after moving it to a different location, or experiencing an unexpected outage, first release, then renew the IP address. Computers on DHCP networks often (but not always) re-establish network connectivity automatically.
