DNS, conditional Forwarder
Posted on 2013-01-09
We are multiple sites connecting over VPN to the head office.
Branch offices have anywhere from 3 to 10 computers.
Each branch office is getting a small file server running 2008. DNS service is also installed.
forwarders were pointed to the dns server at the head office otherwise the branch office could not resolve internal servers
We find that ALL dns requests were being sent to the head office.
The problem is if we loose internet connection at the head office then we risk bringing all the branch sites to a stand still.
Is there a way so that all internet urls will be resolved locally at the brnach sites and for all internal servers it could look up the dns server at the head office.
