At startup, to find a backup browser server, the client MUST do the following:
MachineGroupNameInProgress is set to an empty string.
TokenValue is set to 0.
Initialize BackupBrowserServerTable to an empty table.
If the local master browser for a machine group fails to respond to the GetBackupListRequest after an implementation-defined number of retries, as specified in section 3.1.6, the client MUST force an election by Sending a RequestElection Frame, as specified in section 18.104.22.168.
The GetBackupListRequest and GetBackupListResponse sequences are specified in sections 22.214.171.124.1 and 126.96.36.199.2, respectively. If this sequence does not produce a backup browser server, as specified in section 3.1.6, the initialization MUST fail.<27>
BrowserClientUpTime is set to the time when the browser service was initially started.
