control panel
network and internet connections
network connections
right click the Local Area Connection
properties
double click TCP/IP
check the Obtain IP address Automatically radio button
check the Obtian DNS server address automatically radio button

also, if you are using XP, check the Alternate Configuration tab and make sure that is set to Automatic private IP adress

once this is done open up a DOS prompt and then type:

ipconfig /release
and then
ipconfig/ renew

and hopefully everything should work.
