The Windows 2000 WakeOnLAN feature can be enabled or disabled on a network adapter. It is a completely on or completely off binary feature. If the network adapter supports power management, WakeOnLAN can be enabled on the Power Management tab in the network adapter properties by clicking to select the Allow this device to bring the computer out of standby check box. When enabled, all network adapter programmed packet patterns wake up the computer. When disabled, no packet patterns wake up the computer.
With the following fix in place and a registry change, WakeOnLAN can be enabled only for "magic" packet patterns.
To enable the WakeOnLAN feature for all patterns, select the check the box that enables WakeOnLAN, the same as before.
To enable WakeOnLAN only on magic packet patterns, select the check the box that enables WakeOnLAN and alter the registry setting (by using the .inf file as described in the "Resolution" section) that narrows the patterns to just magic packet patterns.
If WakeOnLAN should be off, clear the check box.
