DNS redirect on a ASA5505

I want to make it so if a user tries to use a different DNS server the request will be redirected to the one they should be using.

I thought this might work but the ASA doesn't do PB routing

ip access-list extended transparent_dns

permit udp any any eq 53

route-map redirect_dns permit 10

match ip address transparent_dns

set ip next-hop ip.of.your.server

route-map redirect_dns permit 20

interface fax/x

ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx

ip policy route-map redirect_dns

I'm assuming this will work on the ASA. Any ideas on another way to do this or if this will even work?

The DNS server is windows 2003

Would policy based NAT or WCCP work for this? If so how would I go about it?
