- * browsers must be queried, but if there are many
- * workgroups, the time spent querying can begin to add up.
- * For small networks (not many workgroups), it is suggested
- * that this variable be set to 0, indicating query all local
- * master browsers. When the network has many workgroups, a
- * reasonable setting for this variable might be around 3.
