Domain Control Settings

[Miguel Nunes]

Hi all,

I am trying to configure a active directory domain controller and I am stucked.

When I use a valid DNS server as the DNS forwarder, the DNS server of FreeNAS changes to an existent node.

Current FreeNAS address is 192.168.0.90

I use as the DNS forwarder a dns server with IP 192.168.0.253. It responds to the domain .home

In network Summary the Name Server gets changed to 192.168.0.103. This node doesn't exist, so a loose name resolution.

What exactly is a dns forwarder?

What exactly is a dns forwarder?

Well, normally a DNS server tries to resolve names by looking in its cache and its zones, and then starts looking out on the internet for the authoritative DNS server. With forwarding you add an intermediate step. Instead of having every DNS server on your network scour the internets, you set up a DNS server that acts as a DNS forwarder. This changes the name resolution process so that

(1) DNS server checks local cache and zones, then
(2) if these don't have the answer, query the forwarder,
(3) if the forwarder can't answer in its local cache or zones then it searches the DNS servers on the internet,
(4) once it has the answer the forwarder sends the response back to the querying DNS server.​

Of course, if the forwarder times out, the querying DNS server just gives up on the forwarder and searches the DNS servers on the internet itself. If you're using samba's internal DNS for the AD DC role, then you need to properly configure a DNS forwarder.

Is the FreeNAS DC configured to have a static address?
Are you trying to add the FreeNAS DC to an existing domain?
