Hi,

bind_query.nasl checks for globally usable nameservers.
It queries kb key "Services/dns", if not set it exits.

I'm finding that sometimes only Services/udp/dns=53 is getting set after 
11002 (dns_server.nasl) is run (according to the KB file), but not 
Services/dns, so bind_query doesn't run its test.

I edited bind_query.nasl (see patch) and I'm now getting correct 
positive results on DNS servers where I've manually confirmed with dig 
that they are global resolvers.

Regards,
