When a non-browser fails, it stops announcing itself. The configured announcement period is between 1 and 12 minutes. If the non-browser has not announced itself after three announcement periods, the master browser removes the computer from the browse list. Therefore, it can take up to 72 minutes before all browsers know of the failure of a nonbrowser. This potential delay includes up to 36 minutes for the master browser to detect the failure and 12 minutes for all of the backup browsers to retrieve the updated list from the master browser.
