DNS Server not responding properly - windows 2003 server

1,136 Views
Last Modified: 2012-06-27
Hi

We have a network with one windows 2003 server acting as DC, DNS server, Terminal Server and DHCP server.

Problem is after our isp changed the internal IP address of our router we had to change the IP of the DNS server. Since this happened noone can browse the network through network neighbourhood. Also I cannot add any users/ computers to the domain through their control panels. nslookup fails saying "cannot find server for address 192.168.0.3: non-existent domain"
It then forwards this to our isp dns server which also says non-existent domain.

Any help would be appreciated.

Is it possible to back up all users and computer accounts etc from AD then delete AD, uninstall DNS and start again?

- On DNS server select Dynamic update( Not Secured Dynamic Update) and then restart your DNS server and domain Controller. This will update the zone.

If this does not work you need to delete the Zone and recreate it.

I ran netdiag from my win2k workstation and the only test that failed was DC list test

It said failed to enumerate DC's by using browser. ERROR_NO_BROWSER_SERVERS_FOUND

WOuld this be as a result of the dns server problem?

I have just deleted the dns zone and am in thr process of recreating it. Will let you know the result. Thanks so far

Ok deleted DNS zone and recreated it. Still encountering the same problems. cannot browse the network and cannot add compuiters to the domain from their end.

I dont know what else to try

Commented:
Do you see the Zone Corropoding to your domain in DNS server?
Under the zone, are there DNS records for your Domain?

Run NSlookup on the computer which you want to add. Verify that it shows correct DNS server IP.

Where is WINS server? You need to verify  its configuraion too.

This is the output from nslookup:

C:\Documents and Settings\cyrusj>nslookup
*** Can't find server name for address 192.168.0.2: Non-existent domain
*** Can't find server name for address 192.168.0.3: Non-existent domain
*** Default servers are not available
Default Server:  UnKnown
Address:  192.168.0.2

the domain shows under dns foward lookup zones as allens.local
Under this there are then entries for the dns server and the computers that have logged on since the rebuild.

WINS is on the same server. What steps do i need to take to verify WINS?

Commented:
192.168.0.2 is this correct IP address of your DNS server(the new IP address)?


Commented:
Are you able to connect to computers in your domain using DNS name like \\ServerName.DomainName.Com

Author

Commented:
The DNS server serves request on both 192.168.0.2 and 192.168.0.3.

Yes I can connect using the DNS names.

Commented:
So now, it looks like you have ony problem left  with WINS. You need to verify that WINS records. Check it shows correct IP addresses.

Commented:
And try NETDiag again

Author

Commented:
WINS is displaying correct ip address for the DNS server.

I ran netdiag and still got the following test failure

DC list test . . . . . . . . . . . : Failed
        Failed to enumerate DCs by using the browser. [ERROR_NO_BROWSER_SERVERS_FOUND]

Milind00 Thanks for all of your help so far!

Are you running DHCP on your network?  Have the new addresses been added to the DHCP scope information?

Author

Commented:
Hi kabaam

Yes the same server is running the dhcp and the scope has been changed to incorporate the new addresses

Commented:
Where are you running this NetDiag.  Try this on the Domain Controller.

Author

Commented:
When trying to run netdiag on the server I get the error message:


The procedure entry point DnsGetPrimaryDomainName_UTF8 could not be located inthe dynamic link library DNSAPI.dll

This file isn't missing, I found it in c:\windows\system32  it is version 5.2.3790.0. Is NetDiag supposed to work with 2003 server?

Commented:
I just verified it works on Win2k Server. Have you installed Windows 2000 Support tools on the server?

Author

Commented:
I only installed netdiag which i downloaded from ms ftp site, under the win2000 resource kit folder. Is there something else I need to install?

Commented:
Only copy will not work. I think you need to install Support tools.
In Windows 2000 Server installation CD, you will find support tools in following location SUPPORT\TOOLS

Author

Commented:
I dont have 2000 server, only 2003 and sbs 2003.

I also have windows 2000 professional but not server.

Commented:
You can install the support tools available with 2003 server on the DC.

Every thing looks fine only following could be a problem.
>>  [WARNING] At least one of the <00> 'WorkStation Service', <03> 'Messenger Service', <20> 'WINS' names is missing.

You need to trubbleshoot....
1. WINS
http://www.jsiinc.com/SUBP/tip7500/rh7501.htm

2. Also reverse lookup zone on the DNS sever as your NSlookup fails
>>nslookup fails saying "cannot find server for address 192.168.0.3: non-existent domain"

I will give milind00 points for helping out so much. Still having the same problem with this server, temporary solution was to promote our backup dc to primary dc and take the other server off line for reinstall.
