This project is read-only.
If you're setting up deSleeper in a network, you may want to read the deSleeper Setup & Architecture Guide as well. This guide will cover the features of deSleeper from simplest to most complex.

Wake Up !

If you're using deSleeper, the first screen you'll see is the Wake Up Page. If you're not setting up servers this might be the only tab you ever use.


To start off you need to supply information about the computer you're trying to wake up (the "target"), and how to get your request from your PC to the target.

Initially you have no targets configured, so click on the New Target button. You can type whatever you like in the Description field, it's for you alone. If you're using deSleeper, it's probably because you want to use the proxy functions. What's a proxy? It's a service that helps get a message from one place to another. If you setup the proxy, then I hope you know the host name, and if you didn't hopefully your friendly network guy can fill in the blanks. Either way, type the name into the proxy field.

You've got two choices for how to identify your target, MAC Address, and host name. If you've never heard of a MAC Address, don't fret, you only need one, and host will do fine. For more advanced users, MAC Address is a little more surefire (though a lot harder to memorize!).

Once that is sorted out, click on Wake Up Now, and you'll either see a nice little success message, or an ugly yellow error. Let's hope for the first.

Network Card Configuration

The second most likely place for a casual user to wander is the Network Card Configuration Page. There's not a lot here, but it consolidates three important items you'd have to hunt all over your PC for otherwise.


The first is you can find out your MAC Address here. Of course, it's the MAC Address of the PC you've just run deSleeper on, not the one you're trying to wake up, but there isn't anything preventing you from installing deSleeper to the PC you want to wake up.

The second item here is the ability to enable you’re network card to listen for the “magic packets”. Such a nice name. Magic packets are the magic that takes a computer sipping 1 watt and turns it back on as if you walked over and pushed the power button.
Once deSleeper has given you a reliable way to wake up your PC remotely, you’ll want to configure the PC to use its built-in power saving features. You can configure these in more detail through your computer’s power options control panel, but for convenience the main setting, the sleep timeout can be updated here.

Service Installation

If no network admin has setup a proxy for you, and “Wake up a machine on your local network” isn’t working, it’s not hard to setup your own. All you need is a PC which will remain on. Most offices, unfortunately, have hundreds of these, so take advantage of one. You install a service through the Service Installation Page


The easiest thing to do is to install deSleeper on the machine you want to use as a proxy, come to this page and click Install. There is no need to change any of the default settings if you don’t understand them.

It will however be helpful to type the names of the machines you want to wake up into the Precache Hosts field, before clicking Install. This option makes your first wake up easier and reliable. It’s optional, but highly recommended.

The other option is to do a remote install. This function is really for more advanced users as it requires access rights the average network user won’t have, and some of the error messages that come back if you’re missing one of those rights are, somewhat of necessity, not all that user friendly.

One common gotcha of remote installs is that .NET 3.5 SP1 needs to be installed before you hit the Install button. To try and prevent confusion, by default, deSleeper checks to see if .NET (and the right version) is installed. But to do so requires a service, the Remote Registry Service, be enabled, which many users disable for security reasons. To skirt this issue, click suppress check for .NET. If one of the installs fails you may have to manually check if .NET is installed.

There is yet one more function available from this page. The Prepare Hosts button will take each PC in the Precache Hosts field and attempt to remotely enable the Wake-On-Lan setting on that PCs network card. Like remove service installs, this requires administrator, or close to it, access rights. For the techies, I’ll mention that this feature, and the remote install feature, is made possible by RCtrlX, a utility from Leon Sodhi. Thank you Leon!


So that’s about it, if you get an error message when doing anything, you’ve got a couple options. The first is to head over to the deSleeper discussion list. The client writes log entries to a file deSleeperClient.log, which is in the same folder as the executable, C:\Program Files\deSleeper (at least for now.. by all standards it should be in AppData but for now it’s in the much easier location).

The service writes most errors to the Application or System Event Logs, which you can get to through Event Viewer. As with all networking related tools, it helps to know a little about what your network is composed of, but in the interest of not overcomplicating this little guide, I’ll leave those as topics for another day.
