Hello

I'm reading some documentation/e-mails from a client that stipulated the following :-

Domain.com is the AD Domain.  This DNS zones for this are domain.com and anotherdomain.com dns zones.  Is this possible ?

I thought that the DNS zone anotherdomain.com would have to have its own AD Domain ? anotherdomain.com hasn't been delegated.

Thanks in advance

If anotherdomain.com has it's own DNS server, you can create a trust relationship between the 2 domains, and after that you can create a secondary dns zone in the domain.com domain.

Hi,

What i understand, you have Active directory integrated DNS for Domain.com and you want a another new Zone for anotherdomain.com.

then yes, it is possible and very simple.

Hi Sven

I'm not sure if I explained this very well.  The correspondence I've read and I'm not sure I agree with states

There is only one AD Domain - domain.com
It has two DNS zones - domain.com and anotherdomain.com

anotherdomain.com does not have an associated AD Domain.

my question is that - is this possible.  Can a DNS zone exist without an associated AD Domain ?

Cheers

Hi Sanosh

So you can have a DNS zone without an associated - that is - related AD Domain.?

anotherdomain.com does not have to have a anotherdomain.com AD domain ?

I was reading in Minasi that every AD Domain needed a related DNS zone and assumed that worked in reverse.

Can you point to some articles that show what you mentioned please for my further knowledge and understanding

Yes, Go to DNS management console, Right click on server name and select new forward lookup zone and follow the wizard.

OR

if you want to create a Zone for External DNS then, you should set up split DNS (sometimes referred to as split horizon DNS).
 On your internal DNS servers, add the domain.com as a new zone.  The new zone should be a primary zone, not a secondary zone because you want the ability for the external and internal zones to contain slightly different records (for some hostnames).

•Add all existing external DNS records on domain.com (external) to your domain.com (internal zone).  This allows you to resolve all names from inside or outside.

•The internal side can point to your internal IP addresses while the external side can point to your public IP addresses (and in some cases, internal will also point to public IP addresses).

so the domain.com AD domain looks after domain.com and anotherdomain.com just by adding anotherdomain.com as a forward lookup zone ? .. this will then be replicated around by the AD Integrated DNS ?

yes.

In addition, you can create reverse lookup zone as well if you want to resolve IP to host name of anotherdomain.com

Not sure if I need to add another question for this, but this leads me on to thinking about when a user logs into a machine that is in the domain.com AD Domain but has its DNS name/ip in the anotherdomain.com dns zone.  I wonder what the point of this could be?
