How to setup Samba with two workgroups?

I have LinuxMCE hybrid in "LinuxMCE" workgroup. I have the rest of my windows computers on another workgroup. They seem not to see each other unless I do this :

1. add

wins support = yes

under [global] section in /etc/samba/smb.conf - it's even better if you change this in /usr/pluto/templates/smb.conf.tmpl

1. add Hybrid's IP as Wins server on all windows clients....
