# ----------------------- Browser Control Options ----------------------------
#
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply

# elections. The default value should be reasonable

# and gives it a slightly higher chance of winning the election

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#
# - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
