I have a Vista Home prem computer that can not resolve internet names.  I can ping internally and ping internet ip address'.  Dns will not resolve the internet name via command  prompt.
I have reset winsock, reset int, ....not luck so far.
any ideas to move me along?
Thanks

How is your computer getting its IP address and DNS settings?

If you are connected directly to the web via a cable/dsl modem, then you should get the DNS settings from your ISP's service.

If you are using a router, or connected through some type of LAN, make sure the IP provider is handing-out a valid DNS server address. Try Google's DNS server, 8.8.4.4

Firebar,
I have the dns set to 8.8.8.8
I can ping 8.8.8.8 from the command prompt, but can not ping www.yahoo.com
the ip address is delivered by my router.  Ipconfig show a good address, gateway and the dns I set.  I have other computers on the same network and they all work fine.

Try flushing the cache.

1. Click the Microsoft Vista Start logo in the bottom left corner of the screen
2. Click All Programs
3. Click Accessories
4. RIGHT-click on Command Prompt
5. Select Run As Administrator
6. In the command window type the following and then hit enter: ipconfig /flushdns

I am using below DNS Server, which work perfectly fine without any issues.
Primary DNS Server:      8.8.8.8
Secondary DNS Server:      4.2.2.2

Also please check whether there any firewall is on for your PC. Disable Windows Firewall service and see if things changes. Also see if AV on your PC is blocking access by any chance.

Try to do ipconfig /flushdns as well.

Yep...tried that also.  I'm running a full malware scan right now.  so far nothing has shown up.
I also am planning on installing SP2 as soon as scan is finished.  Another clue...the computer also has a wireless card and the results are the same.  Connects local and no internet.
Oh my....

Also, let's focus on one connection. Windows acts weird when two NICs are present and functioning on a non-server OS.

Go to device manager. Remove NIC from there. Simply right click and then remove. If possible do a reboot of the PC and then see whether your PC detects the card again. This should refresh all the IP settings on your PC. If you got DHCP let IP get assinged automatically, if not assign the set of IP address and see if things change.

If possible keep only one NIC active.

I'll disable the wireless and remove the nic before the restart.

You want to a use a tool called nslookup. This is command-line tool that is included with Windows, so you already have it. Just open a command prompt, type nslookup, and press enter. Then you can start entering names to resolve. You can change the server it checks against by type "server x.x.x.x", where x.x.x.x is the IP of the new server. Type "quit" when finished.

The other thing I would check is IPv6. You may have a dns server that's returning IPv6 addresses, or a machine that is sending out IPv6 address requests, and then a browser that only knows IPv4 routes to the web. Better disable IPv6 while configuring the IP Address after you have done with the removal and addition of NIC

nslookup resolves fine.  IPv6 is disabled.  I am installed Sp2 now.

Last link which I gave have suggested to have SP installed or have the Hotfix installed.
In above article they have mentioned about some manual config changes. I would suggest to have registry backup first before doing this change.

To work around this problem, manually set the node type in the client computer's registry. To do this, follow these steps:
Click Start, type regedit in the Start Search box, and then press ENTER.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netbt\Parameters
On the Edit menu, point to New, and then click DWORD Value.
Type NodeType, and then press ENTER.
Right-click NodeType, and then click Modify.
In the Value data box, type the desired value, and then click OK.

Note To use P-node name resolution, set this value to 2.
Exit Registry Editor.
