Two forwarders in my internals name servers

it is not just by the browser, it also happens when I do nslookup from the
command line in my windows machine.

By the way my dns in the public segment are running 8.2.3 and in the
internal 8.1.2. Do you think this is an issue.

thank !

Your browser is timing out the query and retrying it. By the second try, the
answer to the query is in your internal nameserver's cache, so the query is
answered quickly.

Note that BIND 8.2.3 supposedly has better forwarder-failover behavior. If
you
haven't already, you might consider upgrading to see if that alleviates the
problem. It's a good idea anyway, for security reasons...
