If you are using DHCP to get an IP address for your computer, then your NIC card 'leases' that IP address for an amount of time, usually a few hours. If you move your computer (this happens most often with laptops, but can also happen with people who cart around their desktops) to a new network, then the IP address that it was assigned from the old network may not be recognized by the new network. In this case, it will appear that no connection can be made.
To fix this problem, users of Win2k and WinXP should start a command prompt window. Then they should type 'ipconfig /release'. An error message of some sort may (or may not) be displayed. Now, type 'ipconfig /renew'. This should have your connection working immediately, but if not, restart.
Users of Win9x/ME should go to the start menu, then 'run'. Type in 'winipcfg'. There are graphical buttons to release and renew the IP addresses of NIC cards. Try to make sure the correct NIC card is selected (if you have more than one installed).
