.B Default:

.SS wins support (G)
This boolean controls if Samba will act as a WINS server. You should
normally set this to true unless you already have another WINS server
on the network.
.B Default:
wins support = yes
.SS wins server (G)
This specifies the DNS name of the WINS server that Samba should
register with. If you have a WINS server on your network then you
should set this to the WINS servers name.
This option only takes effect if Samba is not acting as a WINS server
itself.

This controls what workgroup your server will appear to be in when
