Windows DNS Question

hi
Windows Server 2003 behavior
When the DNS root domain of a new Active Directory forest is created on a Windows Server 2003-based domain controller, two DNS zones are automatically created. One zone is created for the forest root domain; this zone is replicated between all domain controllers in that domain. The other zone is created for the _msdcs.ForestName subdomain; this zone is stored in the forest-wide DNS application directory partition. This partition replicates to all Windows Server 2003-based domain controllers in the forest that are running the Windows Server 2003 DNS Server service.

so you don't need to change anything  its normal in windows 2003 DNS to have 2 Zones , which are automatically created during AD Installation and when you choose Active Directory Integrated DNS

Dear qadsad,

the _msdcs.xyz.com in your DNS contains service records for your Microsoft domain (e.g. those identifyinig your global catalogs) and you should leave this as is (unless if you for a very specific reason is required to manipulate - e.g. through a Domain Prep or similar).

This article explains a bit more: http://www.windowsitpro.com/article/dns/q-what-s-the-dns-_msdcs-zone-for-the-forest-root-domain-used-for-

Kind regards,

I noticed that in some configurations the _msdcs.xyz.com is at the root of the direct zone (and we end up with 2 direct zone) and sometimes it is "included" in the xyz.com (and we are left with only one direct zone: xyz.com)
Is all this normal?
Thanks
 

hi gadsad

do you have Windows 2000 and Windows 2003 Domain Mixed mode or can their was some upgrade from Windows 2000 to Windows 2003 ?
if yes then its normal behavior , Windows 2000 to Windows 2003 Domain migration dose not update DNS configuration and because of that you have _msdcs some places as root zone and some places as a sub-domain .

have a look to the link which i was given it contain all information !
