Windows Server - Netdiag DNS test failed - DNS records for DC not registered

Asked By David Taylor on 17-Jul-11 02:00 AM
I have a WIN 2003 R2 SP2 domain controller ( which is also a DNS server but I can't add computers to my domain. Neither does the DNS server resolve internet urls.

netdiag/fix reports:

Make the Preferred DNS for the W2K3 server .

then do an ipconfig /flushdns and ipconfig /registerdns

then net stop dns & net start dns

the net stop netlogons & net start netlogons.

Hope this will help you.

Thanks for your prompt reply. I did what you advised but netdiag reports the same DNS failure.

The forward lookup zone for the DNS server contains one SOA record, one NS record and four A records.

Of the four A records two point to the same IP address

(same as parent folder) Host (A)
dtserver2 Host (A)

And the other two point to invalid IP addresses.

There is no SRV record (there is another server on the network - Win 2008 hosting one HYper V virtual machine).

Is any of this significant?

Hi David,

If ur DNS server couldnt resolve internet urls. Then Please refer the following Fixes.

Fix 1: Check your Windows HOSTS file – Make sure there’s no entry in the hosts file that maps the website’s address to localhost or an incorrect IP address like – it is a possibility if you have imported some third-party hosts file.

    cmd /k notepad c:\WINDOWS\system32\drivers\etc\hosts

Fix 2: Find Faults in the Pipeline – Paypal website may be up and running but it is possible that the real problem lies with a router that is between you and the computer hosting the Paypal website. Do a traceroute and check for messages like “Request Timed Out” – they will help you find the location of the breakdown.

Type the following command in the Run Window:

    cmd /k tracert – remember to replace abc with address of the website that is unreachable.

Fix 3: Clear DNS Cache – The DNS cache keeps a record of sites that you have recently visited on your computer. If that gets corrupted, you may have issues opening sites that were previously accessible without problems.

    Type cmd /k ipconfig /displaydns in the Run window to see the cache entries. If that unreachable website is listed in the cache, type cmd /k ipconfig /flushdns to clear the cache.

Website May Be Blocked – The chances are rare but it is possible that access to some particular website may be have been restricted by the Office firewall. To test this, send an email to with the problematic website URL in the subject field. If the website is up, you will get a text copy of the web page in an email message.

Fix 4:
Suspend the Anti-Virus and Firewall – If you are running an external software firewall or anti-virus program (like Norton, ZoneAlarm, etc), exit and restart the web browser. Is the problem solved now ?

When nothing works, open and reboot the modem. If that fails, restart your computer and as a final step, call your ISP support.
