HI experts..
We recently demoted our last 2003 DC and upgrade all our DC to 2008 r2. All seems to be working without issues.
However I did notice that in Dns we are missing the "domaindnszones" and "forestdnszones" under our domain folder structure.
so it looks somethihng like this:
MyDomain
_msdcs
_sites
_Tcp
_UPD
(missing _"domainDnsZones")?
(missing _"Forestdnszones")?
This domain was an old NT to 2000 to 2003 upgrade.
my question is since we are completely on a windows 2008 r2 platform should I have to worry about the "domaindnszones" and "forestDnszones" in Dns. And how do I go about recreating this two partitions.
I try to create a new delegations under "ourdomain" called "DomainDnszones" but it stays grayed out. It does populated it with a SOA record tho..
Can someone please upload what a health Dns folder structure should look like that was upgraded from window 2003
thansk in advance

Some of this possibly depends on how exactly you executed the sequence of events to migrate the domain from 2003 to 2008R2.
Fundamentally, ForestDNSZones and DomainDNSZones are the application partitions that are used by Active Directory Integrated DNS. If you did not configure the new DNS servers with AD Integrated DNS, then they would not have replicated the partitions, and taking the last DC offline that did have Integrated DNS would have destroyed those partitions.
Simple fix: Turn on AD Integrated DNS on the new DCs.
If you DID configure the new 2008R2 DC with Integrated DNS, the absence of those nodes may suggest a defect in the replication of those application partitions from the original WS2003 DC(s).
Simple fix: Recreate the partitions using the dnscmd utility.

hello experts.
when i issue the two below commnads
dns /enumdirectorypartitions
dns /directorypartitionsinfo
I see the partitions there? If they are there it won't let me recreated it. however Its not showing up In DNS? We already migrated over to 2008r2 and the old 2003 dns/server has already been removed from the domain using dcpromo/force and metadatacleanup peform.
IM thinking this is a result of upgrades from NT- 2000- 2003. any suggestion how I can clean this up and have DNS be a healthy AC integrated DNS
thks
