Computer can't connect to the internet

[Booshanky]

this one has kind of stumped me. It's an older gateway pc with an intel pro 100 VE network card in it.

I can ping my router, I can ping ip addresses on the internet, but I can't pull up web pages in IE or Firefox and I can't ping any domain names like www.yahoo.com.

I thought it was a simple DNS problem, but I'm using the same DNS server addresses (opendns) as I use on all my other computers. Also, if I type in http://209.131.36.158 rather than http://www.yahoo.com into a browser window (firefox or IE) it doesnt pull up the web page either. Which is strange because you'd think if I can at least ping the IP it should pull it up.

Anyone know what might cause this?

Try doing a repair on the TCP/IP protocol.

 

[Booshanky]

No luck, I ran a program that's supposed to repair tcpip and winsock but I've still got the same problem.

Any chance throwing another machine on there and see what happens? If the TCP/IP stack is ok I would suspect something in the router/firewall area. Port 80 isn't blocked is it?

Here's what I got from Micro$oft

Can ping public IPs but not web sites

Symptoms: 1. You can ping any public IPs but not web sites. 2. The routing table and ipconfig look OK but you can't browse any web sites.

Resolutions: 1. Check the DNS, for example using nslookup to troubleshooting.
2. To test, disable any firewall. If it works after disabling firewall, re-configure the firewall and make sure the firewall doesn't black port 43..
3. Check the status of winsock.dll, wsock32.dll or download winsockfix to fix the problem
4. Also try to disable DNS client service if you don't have domain network or use ipconfig /flushdns to purge the DNS resolver cache.
5. Apply SP.
6. Try to logon another user.
7. Check Event Viewer for any errors
8. Remove and re-install NIC with latest drive.
9. Assign static IP, Gateway and DNS manually.

I've got 30 other PC's on the network so i know it's fine. It's something with this PC specifically.

That pretty much eliminates anything beyond that machine. If you run a tracert does it seem ok? I had a similar problem years ago with Adelphia but that affected the whole network and IIRC I could ping but not resolve. I put a different DNS server address in (not adelphia's ) and it would work fine. But like i said, this was my whoe network.

I thought it was a DNS issue as well at first, but i've got all the same DNS info set up on it as I have with every other computer on the network (such as the one I'm on right now) and they all work just fine.

1. Checked DNS. The other strange thing about it is that if it was a problem with DNS, I should be able to plug the IP address of a site into IE and it should load, but it doesn't.

2. There is no firewall installed.

3. I'm going to try this winsock thing. We'll see if that fixes it.

4. I've tried this, no go.

5. I'm going to install SP2 to see if it fixes it.

6. I'll try this as well.

7. No errors about this stuff.

8. did that, no luck

9. I have assigned all this manually. Still no good.

 

[RiverDog]

Let me know and if I run into any other info I'll pass it on.

 

[Booshanky]

Ok, tried the winsock fixer, that didn't work. I'm in the process of installing SP2. Hopefully that resets it. If that doesnt fix it I'm going to see if maybe I've got another NIC laying around somewhere that I can try.

Another nic is a good idea. You said you can ping a website address, what happens if you try to access google through the IP instead? If you put 66.102.7.99 in the web browser does it work?
