Hi,

You mean they are not replicating or none of your A records get update ?

HKFueyAuthor Commented:
The servers seem to be replicating OK and I'm getting no major errors.

When I ping PC names they seem to be returning the IP6 address when they used to return the IP4 one.

The 2012 DNS server has been added recently.

1. Logon to the server running DNS with Admin privilages
2. run the DNS Manager
3. right-click the DNS server, select properties.
4. on the Interfaces tab, click on "Only the following IP Addresses:"
5. uncheck the IPv6 address(es) that are probably enabled.
6. click OK.

My guess is that this is a default installation and the Interfaces option "All IP Addresses" was selected.

I would do this for all of the DNS Services in your environment.  IMO, its best to have the DNS Service running on only 1 IP address.

Hi Dan,
I've set all 3 to listen on the IP 4 address, I will monitor.

Further info, for some PC's I can see more than one IP4 entry in the forward lookup zone, they are not being deleted

Do you have DHCP server?
it seems your dhcp server is not updating or discard your DNS entries, check the DHCP server credentials.
