DNS error on w3k

[timsayles1]

I am having an error with my w3k DNS server. I am getting the following error when I do a dns lookup:

on a client pc doing a nslookup.

nslookup

http://www.yahoo.com

Server: UnKnown
Address: 206.95.83.14

DNS request timed out.
timeout was 2 seconds.

The server: unknown just means you don't have a reverse lookup zone for the subnet that the DNS server is on.

As far as why the query times out, do you have forwarders enabled? Can you successfully perform any other queries? Does this query only fail on this one client?

I have deleted all my root hits, so it will forward out to my ISP's.

I can ping others, some I cannnot. It is hit a miss.

Have you checked with your ISP to make sure they are not having any issues with their DNS servers?

 

[timsayles1]

they are saying "no"

figures!

Try changing your forwarders to 4.2.2.1. This is Verizon's DNS server, and it is pretty much rock solid. If that makes a difference, you can be pretty sure it's the ISP.

Hi Guys

I've also got the same problem on my w2k3 server. I get the following message
Request to UnKnown timed-out.
Can someone give me detailed instructions on how to create the forward & reverse lookups

thanks

My problem was due to my firewall blocking port 53 for return dns queries. They were never making it back to the server.
