We have an Active Directory network w/ the only DNS Servers running in our HQ building. We have 4 remote offices connected via VPNs. In the interest of cutting back network traffic and keeping the remote offices running even if the tunnel goes down (but their internet connection stays up) we want to add remote DNS Servers to each office. Money, among other things, dictates they be Linux/BSD boxes. We have RedHat runnig DHCP/SAMBA out there already, so we will probably just use them.
I would like the clients to query the local DNS boxes and have those boxes forward the queries to our primary DNS Servers @ HQ for internal addresses and out to the big dot in the sky for internet addresses. I also need the client information to be updated on our Windows 2000 DNS. The remote offices are subnetted but all one domain and needs to stay that way IF possible.
So all this leads to my question(s);
What is the procedure to ADD a BIND server to an existing Windows 2000 AD Domain, using the BIND boxes as secondary/forwarding/caching DNS Servers?
If possible, give me an example of what the named.cof file should look like along
