A company I work for has a local DNS server that answers requests for their domain, foo.com, internally.
Externally, we serve DNS for foo.com with Route 53.
The problem we have is that we have to duplicate any new DNS records, adding them both to their local zone and the external zone. It's amazing how many times we forget this step.
Is it possible to configure a local DNS zone to be non-authoritative and forward requests to the Route 53 zone that it doesn't have in its local zone file?
The research I've done so far has not given me a clear answer. I may be searching for the wrong terminology.
Also, if it matters, they are on Windows Server (not sure which version, but at least 2008).
