Heres my setup:

Computer 1:
Ethernet NIC Cable to Wireless Router
IP 192.168.0.2 / 255.255.255.0 / 192.168.0.5
Static assignment by router
Access to Intranet Yes
Access to Internet Yes

Router: DLink DI-624 Wireless
WAN IP Provided by ISP
LAN IP 192.168.0.5 Static
DHCP Server Yes
Range allowed: 192.168.0.1 to 192.168.0.2

Computer 2:
Wireless NIC to Router
Ethernet NIC Cable to Computer 3
Wireless NIC IP 192.168.0.1 / 255.255.255.0 /
192.168.0.5 - Static assignment by router
(This IP is required for WinXP to enable Internet Connection Sharing on this NIC)
Ethernet NIC IP 10.10.10.5 / 255.255.255.0
Access to Intranet Yes
Access to Internet Yes

Computer 3:
Ethernet NIC Cable to Computer 2
IP 10.10.10.10 / 255.255.255.0 / 10.10.10.5
Access to Intranet Yes
Access to Internet Yes AND NO

Computer 2, running Windows XP Professional has IP Routing Enabled and Internet Connection Sharing Enabled for the Wireless NIC.

Computer 3 can see the router and computers 1 and 2. Computer 3 can ping its way as far as the ISP on the WAN side of the router.

Here's the problem: Computer 3 CANNOT access the internet using any browser (IE Explorer or Netscape).

Why can I ping the ISP but not access the internet with computer 3?

Please Help, Thanks

Computers 2 & 3 is it a Crossover Cable?

Are you using at least 1 Gigabit Ethernet Connection?

If the answer to either of the above is YES either fit a Crossover Cable between Computers 2 & 3 or a a Hub and 2 CAT 5 cables between them as that is the better option.

If you have a gig=bite Ethernet Connection on one of the computers crossover cables don't tend to work very well so it's better to go with a cheap Hub and 2 CAT5 Cables.

I think there is problem with the DNS , if you can ping your ISP and you can't access to internet ,so name resolution is missing.
a)set the DNS as well as Default gateway .
In addition to requiring an IP address, network and dial-up connections on a TCP/IP network may require a mechanism to map computer names to IP addresses ,Four name resolution options are available: DNS, WINS, broadcast name resolution, and the Hosts and Lmhosts files.
b)turn off firewall if you were able to access internet in your browser it means that firewall blocks tcp/ip port 80.
