Ping works fine to an IP address, but fails to resolve to a DNS address

I've seen this a few times as I'm a head technician and the only resolve I've had in the past was a reload of windows.  Thought I'd try and see if anyone else has seen this and found a solution.  

Here is a copy of the command prompt status that may help explain the difficulty of this problem:

C:\Documents and Settings\Nancy>ping

It seems that I've seen this when AOL 8 Plus has been installed on an XP Home version, but I don't know that is the case.

I have reset the IP interface several times with the log showing the below results:

reset   SYSTEM\CurrentControlSet\Services\Netbt\Parameters\Interfaces\Tcpip_{35B1E4A3-BFDC-49A0-84FB-4FA94B269E06}\NetbiosOptions

**This log didn't seem to look like the others I have done in the past.

Any help would be appreciated as it seems I run into this problem about once every quarter or so.

Thanks guys!

I'm not sure why the telnet attempts aren't working, but for DNS problems I would try this first:
ipconfig /flushdns
ipconfig /registerdns

Trust me on this, it wasn't a simple DNS problem.  The Application layer on the XP machine wasn't interacting with the lower layers.  The answer to the solution was to delete the winsock and winsock2 entries from the registry, reboot, and install TCP/IP over the top of the TCP/IP that was currently "installed".  Had to point the Install to the "nettcpip.inf" in the windows/inf directory.  That allows TCP/IP to install over the top of the TCP/IP required for operation of Windows XP.

I have used the /flushdns and /registerdns commands to fix quite a few problems, but this was on a home users pc, and it didn't have anywhere to register to;)

Have a great day.  Hope this helps everyone that might run into this problem twice a year;)

If I were you, I would remove the whole TCP/IP stack, including registry and files.
It changes depending on the OS you are using.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I've already got it working, but I don't know the process or even know if it's possible to "remove" the TCP/IP stack in Windows XP.

It is not possible to remove tcp from XP, it is considered a core component
but XP does have the netshell command

I used the process to remove the Winsock and Winsock2 key from the registry HKLM-System-CurrentControlSet-Services-(winsock/winsock2).  I removed these keys, rebooted.

After the reboot, I went into the Network Connection Propeties, selected install, went to "Have Disk", pointed it to the %SYSTEMROOT%/inf/nettcpip.inf file and then let it install.  Rebooted, and it all worked.  I tried the netsh command as you read above.  Didn't work, only this worked.

Hope this helps someone else!

Blaze, this was a life-saver. Thanks!

I had the exact same problem of Windows 2000 stuck with a tcp/ip configuration and not accepting my dhcp settings.
... followed your steps word by word and life is better now!

I have been working on a problem XP PC for 2 days straight - 16 hours...  I knew that TCP/IP was trashed, but I couldn't figure out how to fix it.

**** How did you know about the nettcpip.inf file?? How did you find this?? ****

I didn't even delete the winsock keys... I just went straight for the Network Properties Install button. After navigating to the nettcpip.inf file and then when it came back with a choice to install the TCP/IP protocol, I was shocked, to say the least! Everything started working immediately after a reboot!!

Through this whole process, I have come across a few people with the same problem, but no solution. I will now go back and pass this along! Thanks again!

Yeah, I figured it out after allot of researc on the Registry and the INF chain in XP.  It worked once so I thought I'd pay to pass it along.  

Super glad this helped someone else!

Thank you BlazeTaylor

Brilliant! Worked perfectly.

I experienced this same problem just now for the second time on one PC. Last time (8 months ago)  I solved it using the Microsoft Knowledgebase article, but this time it just didn't work.

I am so glad I found this post.

Just another thank you post... had exactly the same problem on a friend's laptop just now and followed the process outlined by BlazeTaylor.

First delete the two keys from the registry:

Reboot. Then go to Network Connections, Local Area Connection, Properties, Install, Protocol, Add, Have Disk, C:\WINDOWS\inf, OK, Microsoft, Internet Protocol (TCP/IP), OK. Once it's installed, reboot again.

Note that unlike HighTechGeek's experience, it did not work without first deleting the Winsock keys.
