Ok guys here's the situation.

Setup:
Cable Modem
3 PC's and 1 Laptop.

PC#1 and PC#2) Cannot connect to the internet at all. IE giving Message saying "You cannot search the internet while offline click here to connect"....::click::..."cannot conenct to internet, page cannot be displayed." Or soemthin like that. AIM doesn't work, nothing.

PC#3) AIM can connect to the internet, but IE and other stuff cannot connect.

Laptop)Everything can connect properly, no problems here


We tested all machines on the same Cable Modem.
The ISP said that our cable modem is fine and in working condition, and that the problem may be a firewall problem. What do u guys think our problem is?

I can see several possibilities:

- The ISP allows only ONE computer, and put its recognition code on the laptop.

- The cable modem software is not on PCs 1 and 2, and is only partly configured on #3.

- The wrong port is configured in the browsers.

- The browsers are trying to use a dial-up modem.
