The most commonly reported symptom is that clients cannot resolve A or PTR records for other client machines while using the VAs or the Roaming Client for DNS resolution.
First, in the global portion: requests an address via dhcp, the dhcp server will tell the dns server.
This can occur with non-Windows machines that may not be able to request dynamic updates.
When either type of client (static or DHCP client) initiates an A record update with its authoritative DNS server, it will first start by performing an SOA query for the FQDN of the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.
Tell Power DNS to forward to the master server if the zone is configured as slave.
Masters are determined by the masters field in the domains table.
