domain.local vs. _msdcs.domain.local |
|
|
Gurus,
I am slow to get my head around the true meaning of the forest root domain
and how it is represented in the DNS management console. As I understand it,
in MS Windows 2000+ DNS, you basically have two main zones.
domain.local
_msdcs.domain.local
Here is my point-by-point understanding of these zones, and correct me if
I'm wrong.
1) domain.local is the obvious one. That contains all the host , SRV
records and sites locations for the AD domain. This is the first domain
created in the forest so it would also be called the forest root domain.
2) _msdcs.domain.local zone contains the records of all the Global Catalogs
and all domains in the entire forest. This is essentially the forest root
domain also. So now we have two root domains, do we not? :-)
3) Finally, there is the delegation for _msdcs.domain.local in the
domain.local zone. This delegation zone contains NS records that point to
the _msdcs.domain.local - which again is basically the forest root domain.
BUT. The forest name is said to be the same as the first domain name, in
this case domain.local. So what, my scholarly friends, is the true
representation of the forest root domain? Is it domain.local or is it
_msdcs.domain.local?

It's not two domains in the same sense. _msdcs is a sub-domain and it
continues with .domain.com which is the forest name. The forest and
domain name *could* be the same or it could not if you have multiple
domains deployed in the same forest but the _msdcs remains the same across
all domains (it's forest-wide).
Read the doc and post back if still a question. Or drop a note offline if
you prefer.

My interpretation of that article is that _msdcs.domain.local contains the
records of all the Global Catalogs and the GUIDs of all domains in the
forest. It is a way for child domains of a multi-domain forest to find all
the other domains. So it is not the forest root but in fact a container of
pointers to all domains.

Also, to add another doc to Al's post, look at this too:

But don't forget it's how other domains know who the forest root is too,
which is essential.

LOL! I found that along with another one, and I meant to post the other one,
but now I can't find it! I think I meant to post this one explaining the
SRVs for Spin but could have sworn there was another one I had found:
