[CentOS] DNS problem while trying to join windows 7 to samba3x pdc

I just did a checkconfig on the PDC in question 192.168.6.1.  And I noticed
something that might be nothing but it puzzles me.  The nmb service is set
to "off" at all run levels.  If I check the nmb status it says that it is
stopped.  Doesn't Samba need that for net-bios support?  I am probably
showing my ignorace here but what is the connection between net-bios names
and WINS?
