this is a matter of subnet browsing.
Ich have solved the problem with having samba proxies on the firewalls,
which are routers too.
if you get wins and dns work in the right way, joining a smb domain
in an other subnet works.
Allthough you should simply setup a smb bdc with slave ldap in the other 
subnet. ( this would also help if you loose con to the master ldap )
You can also setup a new domain and trust each other ( but there for
wins and dns must work too )
watch out and read the doku to this parameters
remote browse sync =
    remote announce =
and wins server = x.x.x.x
