If a single AppleTalk network is selected in the Network pop-up menu, the Scour AppleTalk Network command will cause MacPing to “scour” (perform an exhaustive scan of) that network. MacPing sends an NBP LkUp packet to each possible AppleTalk address that is not already in the device list. This often finds additional nodes that were missed in the first scan.
Warning: This test puts a heavy load on certain routers which may cause them to crash. Most network equipment will work well with this test.
