DNS Server not responding properly - windows 2003 server
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?

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_F
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

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?

192.168.0.2 is this correct IP address of your DNS server(the new IP address)?
Are you able to connect to computers in your domain using DNS name like \\ServerName.DomainName.Co
ASKER
The DNS server serves request on both 192.168.0.2 and 192.168.0.3.
Yes I can connect using the DNS names.
Yes I can connect using the DNS names.
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.
And try NETDiag again
ASKER
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_

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

Where are you running this NetDiag. Try this on the Domain Controller.
ASKER
When trying to run netdiag on the server I get the error message:
The procedure entry point DnsGetPrimaryDomainName_UT
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?

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

I dont have 2000 server, only 2003 and sbs 2003.
I also have windows 2000 professional but not server.
I also have windows 2000 professional but not server.
You can install the support tools available with 2003 server on the DC.

ok I ran netdiag on the DC and it passed all tests - see below:

Every thing looks fine only following could be a problem.

You need to trubbleshoot....
1. WINS

2. Also reverse lookup zone on the DNS sever as your NSlookup fails

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