DNS server is not working..

My ISP changed the secondary & tertiary DNS IP addresses from, to, respectively in their system. Now our DNS server is not working. My question is, what will be the next step to solve this problem? I have a cisco router, do I have to change the IP in this router?

Tried These Troubleshooting Steps Yet?

In reply to: DNS server is not working..

My question is about your status in this issue... Do you manage the server? What error messages are you seeing to notify you of the problem? Or...Are you a homeowner with a computer which can't connect? If so, I'll guess you had a static IP address and needed to change it? Yes, No? If it was static, can you change it to automatic detection in the network adapater's properties?

Which operating system are you using?

Tried flushing DNS?

Hope this helps and let us know more.

Hi Grif, I manage the server. This is the error message after I type my address from OpenDNS:

Nameserver trace for

* Looking for who is responsible for and followed

Nameservers for

* returned (NORECORDS)
* returned (SERVFAIL)

I'm using a Linux. A cisco router -> firewall server -> DNS server

I will try later flushing the DNS. As of now, I will take a look the link that you sent. Thanks for the input. I will post the outcome.

A Couple Of Other Thoughts..

In reply to: I will try your advise

Try reinitializing the router.. Turn OFF the computer, turn OFF the router, then turn OFF the modem (if they are separate modem/router). Wait ten minutes, then turn ON the modem, wait two minutes for it to reinitialize, then turn ON the router (if it's separate), wait two minutes, then turn ON the computer.

Of course, you might consider using OpenDNS which works for some..

Hope this helps.

Ok Grif, I will do that. Also, I will try to post some message from utility like nslookup, traceroute. For further analysis.
