Can't access a machine on LAN when it is in sleep mode
Can't access a machine on LAN when it is in sleep mode
- I have a Win7 desktop, one Win7 laptop and one XP laptop. All are on one workgroup and have file sharing between them. When the desktop goes to sleep, I cannot access it from the laptops - I can't even see it. From the Win 7 laptop I go to Network Sharing and access the LAN. I can see my printer and network share drive but not the desktop. I used to be able to see and access it when it was Vista. Now I have to go wake it up and then I can access it.I have wake on LAN set on in BIOS. Any help on settings would be appreciated.

Yeah! I have tested the setting on HP Laptop and Dell Desktop. It seems that windows 7 despite having the settings configured, shuts down the LAN adapter. The result is the same on both the laptop and desktop, that is it does not wake when trying to browse network shares etc. In my test, laptop is using Realtek adapter and the desktop is using Intel adapter.
Clearly, it seems for now a windows 7 issue rather than a network adapter issue.
Ok! I take my above comment back. I now have both my laptop and desktop waking up from sleep mode when accessed over the network. It seems the settings that I had mentioned earlier are the only ones you need, provided you have your Remote Wake Up or Wake on LAN Access set in the BIOS (which you have).
The only thing that I did was to uncheck the seeting, Only allow a magic packet to wake the computer. Left the other two checked, that is, Allow the computer to turn off this device and Allow this device to wake this computer.

i think that by default in windows 7 the power management options are such where the LAN adapter is turned off when the machine goes to sleep mode. to change these setting you can go to the device manger on your desktop and double cllick on the network adapter in question OR you can right click on it and select properties. Then on the properties screen go to Power Management tab and unselect Allow the computer to turn off this device and allow this device to wake computer.

You need to verify the configuration in BIOS. For your reference:
Network Connectivity - Remote wake-up basics

Additionally please check the option “Allow this device to wake the computer” in Device Manager. It is also in the “Power Management” tab.
Arthur Xie - MSFT- Thanks AJay and Arther. It now works after I did Ajay's tip and unchecked the "Only allow a magic packet to wake the computer" setting. I appreciate the help. I guess I'll research to find out what a magic packet is.Thanks again.
- Hi
WOL using Magic Packet is a special way to start a computer that is Totally Off from Remote.
Computer that is a sleep, electronic wise it is still On, so the Magic Packet is not doing any thing.

Ajay, I set all these settings, but still unable to wake up a sleeping computer. I'm on enterprise domain, using remote desktop connection and the destination computer's IP address. I'm unable to RDC to the sleeping computer.
is there something else I'm missing? the sleeping computer is a Dell E4300 with intel 82567LM gigabit, and the computer i'm using to RDC in is a Dell GX620
