Forwarding a specific internal domain name to an external DNS server
Hello experts,
In our organization (domain.com), we have a remote branch which is connected to the internet through a dynamic IP. We use DynDNS to get into the branch using this FQDN: dynamic.domain.com
The problem is, inside the head office, when computers try to locate dynamic.dyndns.org, this DNS request is processed in our DNS server and not found.
How to tell the DNS server to forward request to the external DNS when a specific name is requested?

How to tell the DNS server to forward request to the external DNS when a specific name is requested?

Could you not add a secondary external dns entry on the client Pcs. Ip settings in any client allows for more then 1 dns entry.
Do as suggested by lockreyt
First DNS should point to the dyndns servers and the second DNS of the clients
should point to your internal DNS server. This only involves changes in the client.
You could also try experimenting with Conical name and this modification need to be done in your own DNS.

In your AD DNS put in a cname entry of dynamic.domain.com. and point it to your dynamic.dyndns.org. Entry. That will cause all internal DNS lookups for dynamic.domain.com to get resolved to dynamic.dyndns.org.

The dynamic host is dynamic.ourdomain.com, it's not dynamic.dyndns.org, and that is my problem.
Register the IP under anything other than under ourdomain.com and you should have no problems.

A lot of users are using dynamic.ourdomain.com, so I can't replace it.
let you internal DNS server forward the requests that can not be resolved by him to an external DNS server like your ISP DNS server, this should resolve the external name related to DYNDNS issue.
you know how to set up forwarders on your DNS right?

Yes, Forwarders are already setup on our servers, but they don't forward unknown names to the external DNS server. Is there any way to do so?
if you enable the forwarders and direct them to your ISP DNS server then you should do nothing hence the DNS server looks first in its own zones to resolve addresses and if it doesnt exist they directelly forwared the request to the forwarders DNS servers. you should make sure that on your proxy server or firewall the DNS request to and from outside is permitted.
