A master browser is a server that is configured to manage SMB browse lists and to respond to client requests for them. A Windows server is configured as a master browser by default.
The Oracle Solaris SMB service is not configured as a master browser. The Oracle Solaris SMB service dedicates all of its resources to file sharing.
For browsing to function correctly, each subnet or physical network segment must have a master browser. To make the Oracle Solaris SMB service available through browse lists, the system on which it runs should be located on the same segment and subnet as a Windows server.
Configuring a Windows server improves the performance of browsing and might compensate for the lack of a master browser on some segments.
