 219  *                  The method of locating the list of workgroups varies
 220  *                  depending upon the setting of the context variable

 225  *                  browsers must be queried, but if there are many
 226  *                  workgroups, the time spent querying can begin to add up.
 227  *                  For small networks (not many workgroups), it is suggested
 228  *                  that this variable be set to 0, indicating query all local
