why u're not using a combination between hosts allow and hosts deny
also use bind interfaces...

i cannot follow: how do they get *more* permissions on samba? are u not
using 'security=user || security=domain' ?
also, maybe there's a possibility with DHCP to prevent this?

maybe i cannot follow u. but why u try to block ip's dynamically with
samba. (a.f.a.i.k. u have to restart samba to make effect hosts allow)
why u're not simply using iptables or ipchains?
i think, thats the best way...
