This choice clears the traces and reissues =:=@zone NBP and broadcast Echo lookups for the currently selected network and zone. MacPing then tests the network as usual.
All Zones
This choice scans the network for new zones as if the program restarted. Use this if the network status has changed (i.e., when a new zone has been installed or a connection to a router been lost or re-established). MacPing saves the current zone and network being tested. If possible, it will continue to test this network.
