This is interesting.
Laptop comouter - has IP address (ipconfig) and connects to the internet
without a problem. I am using it now.
Desktop on same router or connected directly to cable modem - gets IP
address, can ping, the IE and Firefox both showit can get to the website
(website found) and waits for reply. Says it cannot display the webpage.
Ipconfig release and renew brings up the same ip address that is valid
(starts with 192) but I cannot see websites on this computer.
Again, the laptop is hooked up to through the same router, gets the same DNS
and similar IP address, but connects and downloads websites. The Desktop does
not.
The desktop doesn't appear to have any software blocking content, ie.
zonealarm. I also reset internet explorer to all default settings.
It is IE7 on Media Center.
 
Yes. I have 2 computers hooked up to the router and one does not have
problems... the other one does. I don't think it is possible to filter one
computer and not the other. Especially because I have tried it on multiple
ports on the router.

Other ideas?

Actually, it is perfectly possible to have a router restrict Internet
access based on a computer's IP or MAC address, irrespective of what
router port to which the computer may be connected ... but if this is
your router, you probably would remember having done that.

And it worked before. The desktop that is having issues connecting doesn't
connect when going directly to the cable modem either. Same issues. So it
seems that it is software somewhere on the system, but I can't identify it.

The router has nothing to do with the issue. It is just the computer doesn't
load web pages. It connects to the internet via ping and dns lookup, but not
a webpage.

Ideas???

What happened between the time things worked and the time they didn't?
Did you remove any malware?

Try these suggestions from MVP Chuck (it may be easiest to try #7 first):

I think there may have been a bad install of google desktop. I do not have it
on my computer... but when looking at winsock and winsock2 -->it showed 2
entries for google desktop search.

Now that I followed #7, the computer is stuck saying that local area
connection is "unplugged" when in fact it isn't. I tried going directly to
the modem and that didnt work. I tried different cables, that didn't work.

The light on the back of the computer where the network cable is connected
is lit.

Do I need to reinstall something so it will see the connection again?

I suggested that you start with #7 of the list of LSP/Winsock fixes
listed on Chuck's site because because it's pretty easy to do in WinXP
sp2. I didn't mean that you should stop there. As Chuck writes:

There are multiple possible solutions to an LSP / Winsock problem, and
not one of them have been found to be consistently more effective than
the others. Some of them may fix some problems, but find additional
problems when run a second time.

Try each solution, if applicable to your system, one after the other,
until your problem is resolved. If any of these tools recommend changes,
and / or make any changes for you, yet the problems are not fully
resolved, continue with the other tools. Then, repeat the entire list.
