DNS Setting in DHCP

When configuring a DHCP scope, what happens if you have both a local (private DNS server listed first) and a public (global DNS server listed second) DNS server listed for clients to do their DNS lookups against? The local DNS server is not configured to do forward lookups. My understanding is that if the Windows host needs to resolve a local DNS name it will query the primary DNS server (the private one) first and this should respond, but if needs to query a public DNS record, what will happen when the local DNS server is unable to fulfil this reply? Does it go on to query the secondary DNS (public) server instead?
Thanks! :)

If a DNS query to the primary DNS server fails to return a result the machine should then try the next DNS server.

The time scale will depend on how long it takes the primary DNS server to respond that it failed to resolve the address (which is probably configured by the admin of that DNS server).
