Backup-Browser Announcements

  • Article

Backup browsers announce themselves in the same manner as non-browsers. However, backup browsers participate in browser elections. Backup browsers connect to the master browser every 12 minutes to obtain updated network-resource browse lists and lists of workgroups and domains. The backup browser caches these lists and returns the browse list to any client that sends out a browse request by making a call, using the NetServerEnum API, to the backup browser. If the backup browser cannot find the master browser, it forces an election.
