This attribute determines whether this service should participate in elections and attempt to become a browse master in the LM-NT-OS/2 realm. If you set this attribute to off, the service does not attempt to become browse master for its network segment. If you set this attribute to on, the service attempts to become browse master for its segment. If you set this attribute to domain, the service becomes the domain browse master; this means that it becomes browse master for its network segment by means of rigged elections. You may only configure one service in a domain as the domain browse master. This includes file services from all vendors, not just TotalNET file services. This attribute defaults to off.
