This problem occurs if there is an active process when the computer enters sleep mode. For example, this problem occurs if a mouse is moved or if any key is pressed on the keyboard as the computer enters sleep mode.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
A magic packet is a standard wake-up frame that targets a specific network interface. In most cases, a wake-up frame or a magic packet enables remote access to a computer that is in a power-saving state. However, some networking protocols use these packets for other purposes. For example, routers use Address Resolution Protocol (ARP) packets to periodically confirm the presence of a computer. Such protocols do not use these packets to wake computers. However, on some networks, network traffic may mistakenly wake a remote computer. These unwanted wake-up events may occur in especially noisy environments such as enterprise networks. By default, the WakeOnLAN feature is disabled in Windows Vista.
