Re: Why adding secondary IP to NIC of DNS servers failed ?

I know, but in this case, both IP and DNS information has been input
manually. Any idea what could have caused this ?

Configuration of the TCP/IP settings for IP address and DNS are
independent. You can have a static IP address, but still select "Obtain
DNS server address automatically", and vice-versa.

Make sure you have both set to static (and have the correct addresses) if
you aren't using DHCP. Later when you switch to DHCP, make sure to switch
both again.

I hope this helps!

On MyApplicationServer on the network 1.0.0.0, here is the IP address
configuration:
The servers which freaked out are all under static IP address
configuration. It is true folks are testing a new DHCP server on given
networks, but since our servers point to static IP address, I think that
is unrelated.


DHCP Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 1.0.0.200
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 1.0.0.254
DNS Servers . . . . . . . . . . . : 200.1.1.2 (note it is pointing to the
original DNS IP address)
200.1.1.1
Primary WINS Server . . . . . Wrong IP ( I don't think this is related
to the DNS issue, but I noticed that WINS IP existing there is invalid)
Secondary WINS Server . . . Wrong IP

Are the people on other networks using a different DHCP server?

What is the order of the preferred DNS servers being sent to clients on
the 200.1.1.x network?

This is the situation:

DNS-ADI-WINS1 = IP=200.1.1.1
DNS-ADI-WINS2 = IP=200.1.1.2

I will have to replace DNS-ADI-WINS1 IP addresses by IP=1.0.0.1 and
1.0.0.2 respectively.
What I did:

I added the IP addresses to the NIC of the DNS servers. That way
addresses 200.1.1.1 and 1.0.0.1 coexist. I did that so people could
start updating firewall rules, static member server IP addresses, DHCP
scope to point to the new DNS IP addresses 10.0.0.x. At scheduled date
I would remove the 200.1.1.1 addresses from the NIC of the respective
DNS-ADI-WINS servers.

Problem:
After adding the secondary 1.x.x.x IP addresses to the DNS servers
TCP/IP properties, people with servers on the specific network
200.1.1.x experienced problems with server resolution. All servers on
200.1.1.1 was unable to successfully return nslookup queries and locate
DNS resources.
Can someone explain what could be causing this ? Servers on other
networks performed OK, only the ones on the same network than the DNS
servers
