I just bought a Western Digital My Book World 2TB HD, which is a network drive. It connects fine when I disable Zone Alarm (ZoneAlarm version: on my Windows XP Sp3 Machine, but it disconnects and can't be accessed and can't be mapped when Zone Alarm is activated. This is true if the drive is connected to the route or directly to the computer's ethernet port. WD support said to try to add an exception then contact Zone Alarm, so I am posting here because I entered the IP address in the trusted zone and still could not connect. Thanks for your help.
