Creating a domain under existing DNS / DHCP environment

Hi,

We are planning to implement an Active Directory domain by running DCPROMO on a windows 2008 server. We currently have linux dns, DHCP & site-to-site VPN.

Windows docs state that a new domain controller wants to do its own DNS.

Is it possible to set up my domain controller so that it uses the existing DNS & DHCP servers? If so then can you please outline any special steps required during setup?

Thanks.

You best bet might be to use Windows 2008 DNS and either forward requests from your Windows 2008 DNS server top your Linux DNS server (as a forwarder). In this way, you get to keep all of your DNS records configured in Linux. Or you can migrate your Linux DNS to Windows 2008.

A 3rd possibility is to use your Linux server as the DNS server for the Windows 2008 domain. If you have a new version of DNS (that supports DDNS- dynamic entries, you are probably OK)

If the Linux DNS server supports SRV records you should be able to set it up. Microsoft has info on it here:

and more on the SRV records here:

As you can see in the Microsoft paper you don't "have" to support dynmaic updates...but it will make your life easier.

We use Microsoft DNS for AD where I am so I'm not super familiar with using BIND for AD records (we do forward external queries to two BIND servers)

Thanks
