Windows 2008 R2 DNS Record Management

Hi All,
I want to map the external domain names to internal IPs on our DNS server for internal LAN users. As it does not work at the moment. Usually I create a new Forward lookup zone and add records in.
But at this client the internal DNS is setup as "office.ABC.co.uk" and external DNS is "ABC.co.uk".
We have records like www.ABC.co.uk, mail.ABC.co.uk, remote.ABC.co.uk that I want to be resolved internally.
But when I created a new forward lookup zone called "ABC.co.uk" it creates a sub-folder called "office" under newly created forward lookup zone (ABC.co.uk), it has quite a few A records entries from LAN PCs etc that should be in original "office.ABC.co.uk" zone. And this results in side effects of slow network resolution etc.

Would appreciate any feedbacks.

Thanks and Regards

I resolve such situations simply by:
- ensuring, domain DHCP clients all use local DNS server
- local DNS server has configured FORWARDERS to resolve public domains
Then, when I need split DNS to resolve, for example, "mail.domain.com" to local mail server "mail.domain.local", I simply add in local DNS zone new A-record, for example:
192.168.1.10    mail.domain.com

This was working without issues with all clients.

Do your external hosts reside in a dmz?
