DNS problems

[AIK]

Hi,

I am unable to access internet on my domain controller, and I believe it is
due to some tangled DNS settings. The reason I say so is because I can
access internet on all my other computers which are on the same network.
Just the domain controller is unable to access internet. The DC can also
ping the wireless router which is the main gateway for all the other
computers. However, when I go ping yahoo.com or something, it says unknown
host. I believe it is because its trying to find yahoo.com locally or
something. I also tried creating a forwarder using my ISPs DNS, but that
didn't help either. What should I do?

On the DC, do you have the IP of the DC as the preferred DNS server?

On the DC, do you have the IP of the DC as the preferred DNS server?

How do I verify that?

BTW, NetDiag on DC returns this:

DNS test . . . . . . . . . . . . . : Failed
[WARNING] Cannot find a primary authoritative DNS server for the
name
'ws01.wirelesssigma.com.'. [ERROR_TIMEOUT]
The name 'ws01.wirelesssigma.com.' may not be registered in DNS.
[FATAL]: The DNS registration for 'ws01.wirelesssigma.com' is
incorrect on all DNS servers.
PASS - All the DNS entries for DC are registered on DNS server
'192.168.1.50' and other DCs also have some of the names registered.

Open up a command window and type:

IPCONFIG /ALL

What shows up there for the DNS configuration?

I have two network cards on the DC. one is connected to another machine
carrying exchange over a crossover cable (192.168.1.50) and the other is
connected to a router. The first one used NICs own ip address for the DNS
Server, and the second uses my ISPs DNS Server (24.153.22.195).

Try:

1. Remove the default gateway from the 192.168.1.50 NIC.

2. Configure the 192.168.2.100 NIC to point to 192.168.1.50 for primary
DNS.

3. Configure Forwarders to point to 24.153.22.195

4. Right click My Network Places and select Properties, click
Advanced/Advanced Settings. Make sure the Local Area Connection for the
192.168.1.50 NIC is at the top of the binding order list.

3. Configure Forwarders to point to 24.153.22.195

where do you configure forwarders?

 

[Doug Sherman [MVP]]

On the server open the DNS console, right click on the servername, and
select Properties. Click the Forwarders tab. If Forwarders is greyed out,
delete the "." zone.
