One computer on network cannot connect to Internet
I've run into a bit of a strange circumstance here, where one of the computers connected through the router suddenly cannot connect to the Internet. No one had touched the computer since last night when it was working fine, and today I'm told it was running Windows Update and restarting just before someone tried to use it. Google's not coming up with anything that works for me, so I thought I'd try here.

This computer's running Windows XP and uses cable Internet through a router that two other computers are hooked up to. Every setting I checked was telling me that the computer was connected to a working internet connection, but no program is able to access it. Restarting the router changed nothing, nor did restarting the computer or running the diagnostic tool Internet Explorer prompted me with. This is what the IE diagnostic tool gave me:

Last diagnostic run time: 01/09/08 16:16:12

And here's what ipconfig said:

I may be missing something obvious, but I'm pretty stumped.

DHCP is disabled, not sure why you run that way.

Let's try a stack reset.

TCP/IP stack repair options for use with Windows XP with SP2.

Start, Run, CMD to open a command prompt:

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reboot the machine.
