Second IP does not register in dns

[Guest]

Archived from groups: microsoft.public.win2000.dns (More info?)

Hi all,
I've 4 server with windows 2000, all of them are domain controllers,
and two of them have the dns server with active directory.

Some days ago we had to set double IP on every server because the
mobile phone provider we use for vpn connections uses 10.0.0.0
subnets, the same of our internal network. Now the servers have a
10.0.132.x and a 192.168.0.x address, the first one for internal use
and the second one for the vpn clients, and vpn is up and running
using ip addresses but when I use the dns it shows me the 10.0.132.x
responses.

I've seen that the second IP do not appear in the dns, and if we
manually create the A record, vpn works great, but the new record
disappears after a few moments.
I've seen many articles about how to avoid to register an ip address
in dns, but how can I force the second IP to register and remain
registered in dns?

Thanks, Luca.

On the interfaces tab, set DNS to listen on this address, too.

No, that's not right, because the server are configured from the
beginning for listening on every ip address, I think also this is the
default behaviour.

The problem is that second IP does not register in dns, I set it
manually but after some time it disappear and only primary IP remains.

Ciao, Luca.

It should, but add this registry entry then:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
On the Edit menu, click Add Value, and then add the following registry
value:
Value name: PublishAddresses
Data type: REG_SZ
Value data: Specify the Internet Protocol (IP) address of the internal
interface. If you want to specify more than one IP address, separate the
addresses by using spaces.

Ok, thanks, this worked for the two dns servers, now in the zone
records they appear with both ip addresses, but what about the other
two domain controllers who are not dns servers? They obviously do not
have the dns section in the registry...
Maybe if I install the dns service onto all the DCs and set the
registry key in all of them? But it seems to me that having 4 dns
servers with 4 DCs is excessive....

Ciao, Luca.

Auto-follow:
i installed the dns service on the other two DCs, and set the registry
key, now all the 4 DCs appear in the dns zone with both IP addresses!!

Thanks again, Luca.

Four DNS servers are not excessive, you can have as many as you need.
Usually two at each location is considered sufficient.

This registry entry should only be applied to the Multi-homed DC that has
these addresses. The rest of your DNS servers should register their own
addresses, not the addresses of another DNS server.
