Products Affected

Solution

A computer's name does not appear on the network after it has been in sleep for three hours. To connect to a computer in sleep mode, type its IP address or DNS name (when applicable). The Chooser, Connect to Server dialog, and Network Browser each provide a field for this purpose.

Note: AppleTalk must be active for a computer to appear in the Chooser.
