Okay, so i'm helping a friend with his home network. The thing is, i've never worked with networking stuff and i don't know much about it.
So here's the problem:

The network consists of 3 macs. They are all connected together and they all share an internet connection.
But, when my friend is tries to connect a vista laptop to the modem via a hard line, (no wireless) one of the macs brings up a message that the IP address is in use.

I've tried to get a new IP address for the laptop, but i don't know how to use vista that well and it just keeps me going in a circle. I also tried on the mac, but i can't figure out if it has a static IP or not. Also, i don't think that he wants to contact his ISP to get a new IP address. I also unplugged the modem and then turned it back on, but it doesn't make a difference.

By the way, if you don't mind, can you explain these things so i will have some better knowledge of networking when something happens like this?

No where do you make mention of a router. I'm curious if one is in the 'network'? With only a single modem and no router present only one computer at a time can communicate through the modem.

More information on all components of the network, will be of great help in diagnosing what you need to do.
