DNS problem: nslookup works but ping does not

[Pancevo1956]

tracert and poing cannot do external name resolution. NSLookup works. See:

F:\>ping

http://www.yahoo.com

Ping request could not find host

http://www.yahoo.com.

Please check the name and try ag
ain.


F:\>nslookup
Default Server: fbrazContrDC.fucbraz.local
Address: 192.168.1.2

>

http://www.yahoo.com

Server: fbrazContrDC.fucbraz.local
Address: 192.168.1.2

Non-authoritative answer:
Name: any-fp.wa1.b.yahoo.com
Addresses: 69.147.125.65, 67.195.160.76
Aliases:

http://www.yahoo.com,

fp.wg1.b.yahoo.com

OS is MS Windows server 2003 SP2 Standar Edition:

"E:\> netsh winsock reset catalog does not resolve problem.

Installing and uninstalling KB945553 did not do the trick, Any idea how to slove the problem?

Have you defined

http://www.yahoo.com

on a local DNS server? You have to understand that Yahoo uses multiple servers so if you are attempting to ping

http://www.yahoo.com,

it is expecting to ping fp.wg1.b.yahoo.com. If another alias is being used you will probably not be able to ping. Do you have any internet forwarders configured on your DNS server?

Let say that I using ISP DNS server. OK. let say I am going to use

http://www.seek.com.au

instead of

http://www.yahooo.com.

The resuilt is the same. I think that the problem has something to do with dnsclient. No firewall problem.

First, tracert and ping are the same thing. Tracert is just a series of pings that are set to time out that helps you trace where the destination is. Next, have you tried pinging by ip address to find out if the problem is name resolution? Try putting yahoo in a host file and see if the ping command works. If it does, then you know you're dns is off. If it doesn't, something else is wrong. Have you checked you're logs? Just some thoughts. Good luck.

The issue is with your internal DNS server and it forwarding name requests to a an outside/Public DNS server:
