Backup-browser Failure

As with a non-browser failure, when a backup browser fails, it may not be removed from the master-browser list for up to 51 minutes. If a browse list cannot be obtained from the missing backup browser, the client selects another backup browser from its cached list of three backups. If all of the client's known backup browsers fail, the client attempts to get a new list of backup browsers from the master browser. If the client is unable to contact the master browser, the client forces an election.
