I'm running Windows Server 2003 domain servers. DNS is running on these servers. We are now opening a branch office.
In the branch office we will have 1 server running Windows Server 2008.
I want the clients in the branch office to authenticate to the windows domain over our site-to-site vpn. However, when doing outside DNS lookups (using web browser, etc) I want them to direct their DNS queries to the server in the branch office. So ultimately they will have a local DNS server.
So far I've only figured out how to handle both external and internal DNS lookups successfully on a domain controller. But since this branch office server is not a domain controller, how can I set things up so that I can still have internal DNS working, AND use the branch office server for doing external lookups?
