Reliable Wake On LAN
Made for complex environments!
Leading PC Power Management Software "Auto Shutdown Manager" not only allows for the intelligent shutdown of computers, laptops, and servers but also for powering them via Wake on LAN over different network segments and VLANs - even over the Internet.
The PC Power Management solution "Auto Shutdown Manager", known for reliable energy savings in professional environments, has been enhanced in the new version by important functions in the area of enterprise Wake On LAN. One of the innovations is the introduction of WOL Proxies. WOL Proxies come into play where directed broadcasts are not working or are not allowed to be used. The administrator can declare computers in remote locations that are already in continuous 24/7 operation to act as WOL proxies for the local network. The central Auto Shutdown Manager Server then uses the WOL proxies to wake computers in the corresponding locations. A wake-up command to the corresponding WOL proxy is send instead of a WOL broadcast. Thus, the Wake on LAN technology can be controlled centrally and used across the enterprise and subsidiaries without having to configure the firewalls and routers.
Moreover, a Wake on WAN (WOW) tool allows users on the road or from their home offices to turn on computers at the company and keep them running as long as they needed them.
Finally, the integration into MCM/SCCM® supports Wake On LAN for MCM/SCCM based software deployments and updates. Individual computers or entire computer collections can be woken or shut down, rebooted, or put into a power saving mode directly from the Configuration Manager Console.

Auto Shutdown Manager is a proven technology that is used by thousands of customers from all over the world.
Auto Shutdown Manager can easily integrate into your MCM (SCCM) system. By using it, you can perform WOL and remote shutdown tasks for devices and device collections across networks, IP segments, VLANs, and the Internet, directly from the MCM console.
One of the benefits of using Auto Shutdown Manager is that it automatically syncs schedules between MCM and the Auto Shutdown Manager. This means that you can efficiently manage scheduled software and update deployments for your devices, without having to worry about manually syncing schedules between the two systems.
Our plugin for Microsoft® Configuration Manager (MCM) provides a user-friendly interface that simplifies the deployment and management of Wake On LAN and remote shutdown tasks. With Auto Shutdown Manager, you can ensure that your devices are efficiently managed, while reducing the time and effort required to manage them.
Starting with Auto Shutdown Manager Release 18.104.22.168 EnviProt offers a plugin for the MCM: Microsoft® Configuration Manager (known before as SCCM: Microsoft System Center Configuration Manager©).
Very simple installation:
The plugin supports all WOL (Wake on LAN) capabilities offered by the Auto Shutdown Manager Server, such as local broadcasts, directed broadcasts and WOL proxies to enable the waking of clients or collections over IP segments, VLANs, and the Internet.
The plugin also supports all remote shutdown and remote sleep modes offered by the Auto Shutdown Manager Server, such as Standby, Hibernate, Restart, Shutdown, and Log Off Users. All modes are applicable to individual clients or collections.
WOL for MCM/SCCM Deployments via Auto Shutdown Manager Server
The MCM/SCCM-Plugin also supports an integrated Application Deployment Scanner that automatically transfers MCM/SCCM schedules to the Auto Shutdown Manager Server for reliable WOL. Supported are schedules for application deployments and updates, as well as packages. All needed data is read via WMI, no further configuration is required.
An application deployment as scheduled in MCM/SCCM (UTC-based):
This deployment transferred into the Auto Shutdown Manager Server WOL Scheduler with the time zone corrected.
More details can be found in the manual. The MCM (SCCM) Plugin is already included into the installation package.

Wake on LAN proxies – wake up remote PCs without using directed broadcasts.
Why WOL proxies
The WOL protocol only allows computers to be woken up in the local IP segment.
In order to enable remote computers to be woken up across network segments and even the Internet, the Auto Shutdown Manager Server offers two technically completely different approaches: Directed Broadcasts and WOL Proxies.
The wake-up packets are sent directly to the endpoint router and triggered there as local broadcasts. However, this procedure is not permitted in most companies for security reasons.
In practice, WOL proxies are used in the vast majority of cases. For this purpose, a computer or a device that supports Java, such as the Raspberry Pi, is configured in the remote network segment for continuous operation (24/7) and, if required, is instructed by the Auto Shutdown Manager server to wake up any computer that is relatively local to it via Wake On LAN. For example, it makes sense to use computers that are in continuous operation anyway (e.g. local servers) - or computers with the lowest possible energy consumption. In the case of smaller networks, this is easy to solve manually; for larger and more complex networks, the automatic generation of WOL proxies described below is useful.
The aim of the automatic WOL proxy generation, optimization, monitoring and maintenance is to ensure that the WOL server operates as reliable and maintenance-free as possible. The analysis can be run daily or according to your own schedule in order to identify changes in the network promptly and, if necessary, to optimize the selection of the WOL proxies fully automatically.
How the automatic WOL proxy generator works
The automatic search for suitable computers as WOL proxy takes place on the basis of a fully automatic analysis of the entire network infrastructure, including the computer types, their current runtimes, group membership and other settings, which are described below. The administrator can exclude unwanted computer types such as notebooks or purely virtual machines. Certain network segments can also be excluded from automatic proxy generation.
A filter allows entire groups to be excluded or treated as preferred. Preference is given to clients that are always on anyway.
A typical example of preferred groups are servers, if they have to run 24/7.
The administrators still have the option of manually determining individual network segments and WOL proxies. The administrator selection has the highest priority and is taken into account in the automatic generation and optimization.
In addition, the administrators have the option of defining a minimum segment size - otherwise it might not make sense to generate WOL proxies for very small segments with only 2 ... 3 clients.
If Raspberries or similar devices with the corresponding EnviProt WOL proxy drivers are used, these are automatically recognized and preferably entered as proxies.
A preview function gives administrators the opportunity to view the results in advance. For this, the generated proxy list is output as an Excel-compatible CSV file.
During the network analysis, care is taken to optimize the number of WOL proxies to a minimum. This is achieved by detecting redundant subnets.
Network A is recognized as redundant and no WOL proxy is generated for it, as all clients can also be reached from network B.
On the other hand, it tries to determine computers that can serve several subnets.
Computer R1 would be selected here because, as a WOL proxy, it can serve all three network segments:
If a WOL proxy PC fails, the Auto Shutdown Manager server tries to find another currently running PC in the target network segment and promote it as a temporary WOL proxy. If the original WOL proxy PC does not respond for a certain period of time, it will automatically be replaced by the next best candidate. This guarantees a seamless and reliable WOL infrastructure without any administrative effort
Try Auto Shutdown Manager's WOL proxies to achieve the most reliable WoL solution across all your networks and VLANs.
WOL for VMs
WOL VMs– Start local virtual machines based on the corresponding WOL Magic Packet (Release 22.214.171.124 or higher)
When this option is enabled, Auto Shutdown Manager will analyze incoming WOL Magic Packages and compare the coded MAC address with those of the known virtual machines. When they match, Auto Shutdown Manager then starts the corresponding VM automatically.
There are two different WOL Portals available - boths FREE
In order to optimally support the different WOL requirements of our customers, there are two different Wake On LAN portals, both of which are hosted on the customer's own intranet.
The WOL process is handled in the background by the required Auto Shutdown Manager Server.
The Basic WOL Portal is a very simple portal, suitable for non-critical use in the intranet with few users.
The Advanced WOL Portal is a more complex WOL portal which authenticates users using Active Directory and only allows assigned computers to be woken up.
Both WOL portals are based on Microsoft's Internet Information Services (IIS) and serve as a supplement to an existing Auto Shutdown Manager infrastructure. Both can be used by our customers free of charge.
To be able to use this portal, a user must first authenticate himself with a valid domain user name and password.
In addition, the WOL Portal administrator must first assign and activate the users and the desired computers.
Now users can simply wake up the computers assigned to them with a click:
The Advanced WOL portal software incl. the installation guide is available free of charge and can be downloaded here.
This basic WOL Portal is typically operated withn the company's intranet. In the simplest case, users only need the portal address and the FQDN name of their workstation.
The Basic WOL portal software incl. the installation guide is available free of charge and can be downloaded here.
The administrator is free at any time to centrally allow or disallow portal based wake-up calls.
A password can be specified for the wake-up call.
Computers that should not be woken up via the portal can be blocked using an exception list. Individual computers can be listed, or REGEX-based expressions can also be used. More details and examples can be found in the instructions included with the download.
