What it sounds like is that he is using a router of some type, most likely something small for home use like a 4 port linksys. what you want to do is make sure the nic is set to obtain an ip address automatically. If it is and he still cannot connect try this:

1.) go to start > run > and type cmd
2.) at the prompt type ipconfig /all
you will get something like this

Windows IP Configuration

Host Name . . . . . . . . . . . . : computername
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection 4:

Connection-specific DNS Suffix . : yourisp.com
Description . . . . . . . . . . . : Intel 8255x-based PCI Ethernet Adapter (10/100) #2
Physical Address. . . . . . . . . : 00-80-29
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 169.254.....
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
DHCP Server . . . . . . . . . . . :
DNS Servers . . . . . . . . . . . :
3.) if you ip is 169.254.....
type
ipconfig /release
ipconfig / flshdns

4.) then go to your nic card setings in local area connection and uninstall tcp/ip for your nic
5.) reboot and reinstall tcp/ip
6.) shutdown the computer / router / cablemodem
7.) turn on cable modem first and let it light up all the way
8.) turn on router and wait 1 min.
9.) boot up computer and repeat step 2
10.) check your ip and see if it is something like 192.168.1.100
if it is you should be able to connect
if not check for conflicts in device manager such as irq / also make sure it is properly installed under network adapters

Ok all some of you are right on the money we found out that it was just wrong configuration, although I still dont understand how it became that way?He and I both play on-line games like counterstrike,tfc,half-life,starwars galaxies, dont know if anyone is able to mess around with his settings when we are connected to those games? but installing norton firewall this weekend so that should stop any direct attacks then we'll just wait and see if it happens agian.thanks alot to all of you for replies everbit helps......
