Yeah, I know that "primary dns" and "secondary dns" is a false statement,
cause the "primary" is the quickest answering server. Anyway my "secondary"
server it's a Win2003 PDC used for our windows domain and we saw that logon
performances improved...but probably it's a misconfiguration in the FQDN of
the win2003 server...it's domain is actually different from our DNS domain
(whilst in dnsmasq is XXXX.YYY, the win2k3 one is AAA.XXXX.YYY)

Thank you for the hint :)
