SYMPTOMS

On a Windows Vista-based computer, you turn on the "wake from sleep" option for a network adapter that supports Wake On LAN (WOL) functionality. After you do this, the computer does not wake from sleep when it receives network traffic.

For example, you click to select the Allow this device to wake the computer check box on the Power Management tab of the properties dialog box for the network adapter. You install the sample PassThru driver that is included in the Microsoft Windows Driver Kit (WDK), or you install a virus scanner that uses the same PassThru driver technology. Then, you put the computer to sleep. However, the computer does not wake from sleep when you send a PING command or a "magic" packet.

WORKAROUND

To work around this problem, use one of the following methods:
  • Uninstall the sample PassThru driver.
  • Contact the manufacturer of your virus scanning program to find out if a program update is available that does not exhibit this problem. You may have to use a different virus scanning program.
