Are you using an ms dns server? An ms dns server can generate netbios
queries.

If yes, check the dns server help about 'WINS lookup integration'.

Quoted: "The presence of a WINS resource record can instruct the DNS service
to use WINS to look up any forward queries for host names or names that are
not found in the zone database."
