This is a DNS lookup from an application program on host 192.168.0.1

This is a DNS lookup from your named program on host 192.168.0.1 port 53
In other words: a request made on behalf of one of your windows systems.

Named will always make a DNS lookup request from port 53 to port 53 on 
the destination server.

DO you have a rule like

ignore udp upd.dest=udp.domain,udp.source=udp.domain

Remove this or turn this into an accept line.
