Wake from sleep when acceded from network?

Thanks for your help, i am running server 2008. Sorry I completely forgot about the OS in my first post.
Just discovered that there isn't a sleep option listed under the power setting on the server. I just barely install it a few days ago and I don't think I have run a windows update yet. Hopefully that will fix the problem.

Will try it when I get the sleep function working.

thanks for your help

Thanks guys for your help, got it to wake up when I tryed to access it!! But it doesn't seem to want to go back to sleep again, after that. Do I need to be loged in for my user setting to apply? This is the Administrator account I am useing.

I just needed to install my video card drivers, then the sleep option appeard in the power settings.

I removed the screen from my server, So the only why I can access it now is remotely. But I think I need to be logged in locally to have the power setting apply.
Because I have the power button set to put computer to sleep when pressed, and it doesn't do anything when I press it.

Do you know how to apply user setting for the default user, that is used when on the log in screen?

I did unplug the Ethernet cable so I can't be stopped going to sleep by the network card.

I don't think I do, Unless hyper V installs by default. Haven't install anything, server related (yet).

Ok did the powercfg.exe /hibernate on. nothing happened. So I am assuming it was all ready on.

I am rendering some video on the server, So I can't test it to see if it worked tell it is done

Yep I did have UAC enabled. Now that it is disabled it is working!!!

But the wake up is very sensitive. Even if I have one other computer on the network, it will go to sleep then wake up with in a few seconds.

Sorry for the long response time I was out of town for a few day

Yes I think your are right.
Changing the power setting to power save didn't make any difference.

In fact, I don't think a router would do the deal either. A router will ping all nodes connected to it once in a while to know what is still around, which will wake your server up every time. The way that thing works is, every time the NIC receives a packet (any), it will wake the server up. I don't believe there is any way to decrease the "sensibility" of the NIC to wake up the server with some packets.

I might have some suggestion for you instead.

If you only access your data server from another PC, you could use wake on lan instead. That would means you could power off the server. When you need it, launch the wake on lan app on the other PC, and power up the server.

Another way would be to decrease all performance of your server to the minimum. Since, I suppose, it is only a data server, you don't need much performance. Even converting it to a minimal linux to create an ftp server, you could lower the perf even more.

Last way would be to get a NAS instead

I might have found what you are looking for. I am quite unsure on how it works, and if you can even do it, but I think its worth a look.

If you look in the example, it states "file sharing".

Let me know if it works, and how you did it
