Hi friends, I need to install a new server as Replica DC but on our LAN we
use a Linksys Router as DNS, I mean, we don't have a DNS server under
windows platform, when I execute dcpromo and select to install the new
server in an existing domain it show me an error telling: Cannot consult DNS
to find DC (something related to _SRV)

my question...

Can I install a replica DC without a DNS server?

If not, Can I install DNS server first on my new server, then execute
dcpromo to convert it as replica DC (with DNS server already running) ??

HB

Hi Mr Weber, right now we have a DC running without a DNS under windows, our
Router act as DHCP and use DNS of our ISP, and now I need to install a new
server as Replica DC but I found this problem (explained before) .....

Hello Euro,

If you talk about a replica DC means that you have one DC running? So how
is DNS handled there? Please describe more in detail what you have. Active
directory relies on a well ggod configured DNS.
I can strongly recommend to use the windows DNS server and disable the router
dns, this will create a lot of unneeded problems.

Best regards

1. Stop using the DNS on the NAT Box.
2. Install DNS on the Server,...but leave it unconfigured
3. "Replica DC" to me implies that their is another DC somewhere that this
one is supposed to "replicate"??? Point the TCP/IP Config DNS to the same
DNS IP# that the existing Domain Controller is using. If their is no other
DC then there is no "Domain",..then do Step #5 next,..and then step #4 and
create a new Domain.
4. Run DC Promo to make it a Domain Controller
5. Change the TCP/IP Config DNS to point to itself
6. In the configuration of the DNS Service add the ISP's DNS to the
Forwarders List. Make sure the Linksys box allows the DC to make outbound
DNS queries,..by default it already should be.

Now on the original Domain Controller,..you're gonna have to straighten that
mess out....But if there was no other Domain Controller then you are already
done and skip the rest of this post.

1. Wait till the new DC above has fully replicated and has a complete copy
of AD and the Local DNS on that server has fully replicated it entries
2. Run DCPromo on the original DC to demote it to a member server.
3. Install DNS on the machine but leave it unconfigured. I am assuming it
was using something else for DNS before that??? But if DNS was already
installed on it and being used, *uninstall* DNS, and then reinstall it and
leave it unconfigured.
4. Set the TCP/IP Config DNS to point to the other DC you built earlier
5. Run DCPromo to make it a Domain Controller.
6. Reset the TCP/IP Config DNS to point to itself, and second to the other
DC. Follow this pattern on both DCs
7. In the configuration of the DNS Service add the ISP's DNS to the
Forwarders List. Make sure the Linksys box allows the DC to make outbound
DNS queries,..by default it already should be.
8. Manually make sure that at least one of them is a Global Catalog Server.
9. Adjust the FSMO Roles if you feel you need to. Use this article to guide
you:

Hello Euro,

Please post an unedited ipconfig /all from the running DC and the new machine.
As i said before to prevent you for additional problems use the windows DNS
server and configure a forwarder to the ISP's DNS server. Also use windows
DHCP for correct updating of the DNS records from clients. Your domain will
not work properly with this setup.
