Preferred and Alternate DNS servers

I thought I knew the answer to this until someone asked. We have a W2K3
domain with AD integrated dns servers. We put in one server as the
preferred and one as the alternate dns server when we set up TCP/IP on a
network adapter. What happens when someone tries to resolve a name that the
preferred server knows nothing about? I say it looks at the forwarder which
lists our external DNS servers and goes out the gateway to that address to
resolve the name.

Does the alternate server get queried as well? The only role I think it has
is in case the preferred server is down. Is this correct, or does it look
here as well?
