Hi,

ISC's DHCP server is capable of passing the IP of a WINS server so in theory 
it is possible to write some script to fetch that IP from the DHCP response 
and modify it in the client's smb.conf.
The DHCP server has this configuration for a WINS server:

option netbios-name-servers [ipaddress], [ipaddress], ... ; 

Hope this is of some help.

Greetz,
