Solved Unable to wake from Sleep state with Remote Desktop

With Windows XP Pro, I could waken the computer by initiating a Remote Desktop Connection to it. After installing Windows 8 Pro on same hardware, Remote Desktop works fine when the computer is awake but is unable to wake the computer from a sleep state.
I have tried all combinations of Power Management settings under NIC Properties and confirmed that wake on pattern match and wake on magic packet are enabled. Under advanced power management, disabling hibernation and/or turning off hybrid sleep make no difference. With the default Microsoft/Broadcom NIC driver for Windows 8, whenever the computer sleeps, it always powers off the NIC - and once the NIC has been powered off it is unable to wake the computer on receipt of traffic.
Hardware is HP DC5700 SFF core 2 duo. NIC is Broadcom NetXtreme Gigabit Ethernet. BIOS power management settings are configured to support wake up on LAN.

Solved this myself...

I resolved this issue myself. Following is a summary of what I did:
1. From the command prompt enter netsh interface ipv4 show interfaces . This will list all available network interfaces. Note the index (labeled Idx ) of the target network adapter. Now enter
netsh interface ipv4 set interface [index] forcearpndwolpattern=enabled to force the network adapter to wake on Address Resolution Protocol (ARP) and Neighbor Solicitation (NS) messages. If the command is successful, OK is returned.
2. Under the Driver tab of NIC Properties, click Update Driver and manually force the installation of Broadcom driver version 14.8.1.13 dated 2/23/2012.
3. Under the Power Management tab of NIC Properties, check the box for "Allow the computer to turn off this device to save power", check the box for "Allow this device to wake the computer" and uncheck the box for "Only allow a magic packet to wake the computer". Click OK.
4. Reboot and then check Power Management tab of NIC Properties and confirm that the settings applied in step 3 above are persistent.
The above assumes the operating system is Windows 8 Pro, the network adaptor is a Broadcom Netxtreme Gigabit adaptor and that all other settings required for Remote Desktop to function have already been correctly applied.
After completing the above steps, when the computer sleeps there will be one green led and one amber led on the NIC versus both green when the computer is awake. The computer will now waken in response to an attempted Remote Desktop connection from a Windows 7 or Windows 8 computer.

I've had a similar problem trying to wake a PC from sleep by sending a magic packet via mobile phone. I had done similar to you have in your original post but could only get the PC to wake from a full shutdown (even though MS say this shouldn't work). Can't get it to wake from sleep though with a magic packet.

I wonder if these steps will fix my issues? Where did you find this info? I specifically need it to respond to a magic packet however, and there is no updated driver for my NIC afaik though.

Will give it a try later.

I consulted many sources but one of the most helpful was the following TechNet article directed at Windows 7 and equally applicable to Windows 8:
Power Management for Network Devices in Windows 7

The steps I provided in my original post should allow you to wake the PC with a magic packet. If you want only a magic packet to wake your PC, then check all 3 boxes under the Power Management tab of NIC Properties.
