after issuing "nslookup" at the command prompt from any W2K workstation, I obtain a response :
*** Can't find server name for address 192.168.1.27 : Non-existent domain
This address belongs however to a domain controller, on which DNS and WINS services are running. The DHCP-service is running on a different domain controller. DHCP adds options Router, DNS Servers=the above address as well as the address of the ISP's DNS server, WINS/NBNS Servers (again running on 192.168.1.27), and WINS/NBT Node Type 0x8.
In the DNS server, I have also created the reverse-lookup zone. It contains a zone "192.168.1.x Subnet", which shows PTR records for all domain controllers.

What could be causing this problem ?
 
Found the answer myself...;-)
I discovered for the server that has the DNS server service, that it is no good to enter the address of the ISP's DNS server. Nor an address of any external DNS server.
Apparently you have to enter the server's own IP address in the field "preferred DNS server".
Otherwise all DNS queries are not processed by the DNS server, even if via DHCP the address of this internal DNS server is passed on to the clients.
The request is passed on to external DNS servers (ie of your ISP) via the list of Forwarders designated in the DNS console.
 
Thats correct.

How did you get it working? Where did you put the value, specifically? Do you mean you have to put the DNS servers own internal IP as the forwarder?

You put the IP of your ISP in the forwarder.

But the DNS servers own IP in its own Ip config tab.

What do you put in the tab where it says 'DNS DOMAIN'?

AM
 
"Any other domain" is the default that works for us.

Still doesnt work for me, I must be doing something wrong.

I have Any other domain.
Below that I have my ISP's DNS servers listed.
The server itself is pointed to itself for DNS.

What am I leaving out?

How do you mean its not working. What are the symptoms now?

Is is configured as a root server?

I just mean that NS lookup still does not work. I get the same result, non existant domain.

AM
 
Are you puting the IP address of your DNS server not your ISP's in the workstations ip configuration?

The stations must look to your server for resolution.
