Cannot demote dc - Last DNS server for zone

Hi, having trouble demoting a domain controller (2008 integrated DNS)
I get an error complaining about this dc being the last dns for the following ad integrated zone.
This is a primary zone (not the same domain that the dc itself is on), ad integrated, accepting secure and non-secure updates.
thnks.

If you check the properties of the zone on the Dc you are trying to demote, under Type click Change and uncheck the box for Store in Active Directory.  Then restart the DNS services.

You cannot have a DNS zone stored in AD if the DNS server is not a domain controller.

This is why you are receiving the error when trying to DCPROMO

If the zone is AD-integrated, then it should be replicated to all other DC's.
Verify this on the other DC's and check replication.
One worst case scenario would be to use the DCPROMO / forceremoval & then do a metadata cleanup afterwards. How many DC's do you have in total?

Why would you want to do a forceremoval, it's a failry simply fix!!

Chev_PCNCommented:
As mentioned - worst case scenario only if the DC will not demote gracefully.

Glen KnightCommented:
But the reason it will not demote gracefully is because it has a zone on it which is AD integrated, it's a simple fix.

It is AD integrated...

So change it so that it isn't AD Integrated and you will then be able to demote the server.
