Some Windows implementations automatically do DNS lookups to multicast 
addresses like fec0:0:0:ffff::[123].  You should see these as DNS servers 
in ipconfig/all output.

This is some form of Windows XP; not sure if this occurs on all service 
packs.

If this is true, configuring the localDNS resolvers to listen and respond 
on these multicast addresses might do the trick.

Maybe someone who actually have Win XP (I don't) can elaborate on this ?
