We're using pdnsd at a remote station. It is configured to query the DNS servers at our main site.
The issue is when the connection at the remote site goes down the computers at the remote site all of a sudden cannot reach internal resources.
The host running pdnsd has local server names in its /etc/hosts file. Pdnsd's configuration default in the sources section is the "/etc/hosts" file.

I confirmed that the TTL being delivered to the pdnsd from the root servers is 1 hour.
I've also confirmed the TTL in the /etc/hosts file is 1 day.
However, when the connection goes down those computers cannot reach their internal servers.
So how does pdnsd decide if it's going to use the "root servers" or the "/etc/hosts" file to reslove names to IP addresses?

Thank you,
pender

This the configuration: I took out the IP's of our servers.

/etc/default/pdnsd AUTO_MODE is set and that
