DNS on my 2k server will not resolve www.bestbuy.ca

[raylward]

We have a win2000 server running with active directory integrated dns on our network. All of the client computers on our domain are running windows xp pro and use the DNS from our server. The other day, one of the secretaries asked me if I was blocking

http://www.bestbuy.ca

with our firewall. I was not blocking this site so I checked her computer to see what was happening. When I tried to access

http://www.bestbuy.ca

from the web address bar, the page status indicator would just slowly move along and then finally, instead of the site ending up in front of me, I get a yahoo search page that shows me the same link for best buy in a search page. The link also shows that best buy’s address is "

http://www.bestbuy.ca".

So you click on the link and status bar sluggishly moves along and then you finally get a page that says "the page cannot be displayed". I went to the command prompt and tried to ping

http://www.bestbuy.ca

but had no responses. I then went and tried all of the above steps again on three different machines ending with the same results. I finally went to the TCP-IP settings on my machine and cleared the dns address for our 2k server and entered our ISP DNS instead. Now when I try to reach

http://www.bestbuy.ca,

it works! So I now know that there is a problem with my DNS on my 2k server. It has been running rock solid for two and a half years until this. All other internet sites can be reached except the one I mentioned. So, what is one to do in this situation? I have looked at my dns and cleared the cache and what not, but have had no success in fixing this issue. Any ideas as to what I should do next with my DNS server?

Have DNS forwarding enabled in your DNS server?

The DNS should be set up as follows:

1. All clients use your internal DNS only
2. Your DNS server has the root "." zone deleted.
3. Your DNS has a forwarder set up to use your ISP's DNS to resolve internet addresses.

Use the advanced view in DNS and clear the cached lookups in the forward lookup zones. Now you should be able to resolve it.

also... check for an entry in the hosts file.

Thanks for the advice.....I had no forwarders setup. I am suprised that I got away with it for the last two years without incident. What did you mean by this comment " Your DNS server has the root "." zone deleted."

Please clarify

Otherwise, all websites are resolving nicley after I inputed my ISP's dns into my forwarders.

You won't be able to configure forwarders in your DNS server if it is already configured as a root DNS server ("."). If you have configured your DNS server as a root server, you will see a root zone. Deleting this zone makes it a normal DNS server. Now you can proceed with configuring forwarders. This will enable your DNS server to forward unresolved DNS queries to the ISPs DNS servers. In the "Forwarders" tab, add your ISPs DNS server IP addresses in order.
