go to your "start menu"..
go to "run"
a black screen should pop up
do ipconfig -all (this reviews by suming up the information)
if you see a ip address
you should go ipconfig -refresh
this updates anything in the operating system.
(IF it still doesn't work after that)
if not then go to internet explorer
"tools"
"internet options" and it gives you a
the tab that states "connections"
you can either add your modem if you have 56k
or go to lan "settings" and have it automatically obtain a random ip address.
Or if your on a network....to input a dynamic Ip address giving to you by the router.
for futher information.....just contact me on aim.
