DNS issue, ping resolves IP, but times out, on any attempt.


I am experiancing a strange issue.
I am running dual DNS/DC servers. One as the main, and another as a backup.
When I attempt a ping, for say:  google.com, It resolves the IP, but then proceeds to time out on any ping attempt. I can ping any public name, get the IP, enter that IP into a browser and it works fine. I just cannot seem connect or ping to anything durring a ping test.
When I run a NSLOOKUP, it work just fine.
For example, I do the following command:  nslookup google.com
The response:
Server:  'My DSN server'
Address: (my dns address)

Non-authorative Answer:
Name:  google.com

Yet, when I ping anything, it shows the IP and then proceeds to time-out.
I have tried resetting the Stack and flushing DNS on my machine, etc.

Any Ideas of what to try next?

Most likely Firewall is blocking the ping request.

If nslookup is working properly then DNS is working correctly.

Type in ping www.google.com

Yea, also tried the WWW in front of all attempts.
I am Running an ASA, is there a way to block all outbound ping requests?
I know how to config inbound ICMP requests, but have never needed to deal with outbound pings, etc.

Cisco ASA 5510 (or something like that)

Can you ping the IP addresses?
icarus2256Author Commented:
No, like I said, I run a ping command with either www.google.com or google.com (yahoo.com, etc - does not matter): PING www.google.com
Pinging www.1.google.com []

Request Timed Out
Request Times Out..
etc, etc

Yet, I can go to a browser and enter the IP direct and it will pull right up.
Also, I can enter the name and not IP into URL and it too works!!
I think its just a senario where the outbound ICMP on my ASA is desabled.
I am not even sure if thats an option or even do'able, but about the only thing I can think of.

No what I'm saying is can you type ping and get a response?
Darius GhassemCommented:
What I believe is your DNS is solid there are no issues but you have a firewall or router disabled ping requests (ICMP)
