QOS packet scheduler and group policy

hi,

did anyone know how to configure a priority of dns ports (and other ports) on QOS on windows 2003? hard to understand the group policy "explain" tab on 'qos packet scheduler', no elaboration on how to use it.

thanks for any comment you may add.

i think i can't prioritize ports here, only packets policy...
