Wake on LAN ToolWake on LAN


The Wake on LAN Tool of Desktop Central helps to schedule booting of systems in the Windows Network remotely. It allows you to create different task to group the computers and specify a time to boot the machines in that task.

Waking Up Computers Manually

Desktop Central has the ability to wake up computers within the same subnet and different subnets. When a task is initiated to wake up a computer, the target computer's broadcast address is sent to the Desktop Central agents which are live in that subnet. Desktop Central agent version should be 8.2.93.W or above to perform the wake up task. If you are trying to wake up a computer which belongs to a different subnet, then at least one of the computer in the specified subnet which has the Desktop Central agent should to be live to perform the wake up task.  

You can Wake computers on LAN manually using Desktop Central by following the steps mentioned below:

  1. Click the Tools tab
  2. Click Wake On LAN
  3. Click Add Computers
  4. Against Select Type, choose Computer
  5. Select a domain or workgroup to view the computers in it
  6. Select the required computers to add
  7. Click OK
  8. Select the specific computers  click Wake Up Now
    you can see that the wake up process has been initiated and the status will be updated.

Note: When computers running on Windows 8 operating system are shutdown, we will not be able to wake up those computers. To know more details on the work around for waking up those computers, refer to this article:http://support.microsoft.com/kb/2776718 .

Creating and Scheduling Wake on LAN Tasks

To create a Wake on LAN task, follow the steps below:

Step 1: Define Task

  1. Select the Tools tab from the Desktop Central client. This opens the list of tools that can be run on the network machines.

  2. Click the Wake on LAN tool listed under the Windows Tools category to open the task details page. This will list all the Wake on LAN tasks that have been created.

  3. Click the Schedule Wake Up button to create a new task and specify the following:

    1. Provide a name of the task

    2. Choose the speed for the Wake on LAN task. Depending upon the selected speed, Desktop Central allocates more threads to complete the task.

    3. Waiting time after wake up: Specify the time in minutes after which the status gets updated in the Desktop Central client.

    4. Verify the computers already powered up before waking up: Select this option, if you wish to check the status before attempting to boot the machine.

    5. Use broadcast to wake up computers: Desktop Central supports sending both unicast and broadcast packets to boot the machines. When this option is not selected, Desktop Central first sends an unicast WOL packet to the machine to boot and check whether the machine is booted. If this fails, it broadcasts the WOL packet in the whole subnet.

    6. Resolve IP Address on each schedule: Select this option to resolve the IP Addresses of the machines during every schedule.

Step 2: Select Computers

    1. Click Add Computers button to choose the computers for this task. The selected computers gets added to the table below.

    2. Broadcasting of the WOL packtes is based on the subnet address of the computers. If the subnet address is blank of if it is incorrect, the task may fail. You can either click the Modify Details icon and update the subnet address and Mac Address manually for individual computers ate select the computers in the same subnet and use the Set Subnet Address button to update the Subnet Address of multiple computers.

Step 3: Define Scheduler

  1. Once: To run the task only once. You need to specify the date and time.

  2. Daily: To run the task daily. Specify the time and duration to run the task.

  3. Weekly: To run the task on specific day(s) in a week. Specify the time, start date, and days on which the task has to be run.

  4. Monthly: To run the task specific day every month(s). You need to specify starting time, select a day and select a month/months.

Step 4: Deploy Task

Click the Submit button to deploy this task. The tasks will be run at the scheduled time and interval. The status of the tasks and its execution history can be verified from the Task Details page.

Configuring Wake on LAN

BIOS Settings

The Wake-On-LAN functionality is generally disabled by default. The option to enable Wake-On-LAN is different with each computer manufacturer. The most common method adopted across different PC's are as follows:

  1. During the computer’s power-on self-test enter the BIOS setting screen by pressing the F1, INS, or DEL keys.

  2. Select Power settings. Check for Power Up Control.

  3. Enable settings related to Power Up on PCI card, LAN, or Network.

  4. Click Save and exit the BIOS settings.

Operating System (OS) Settings

In some Windows OS, the drivers can enable the Wake ON LAN features of network adapters. For example in Windows 2000, click Power Management tab and under the Adapters properties, select the option Allow this device to bring the computer out of standby.

Alternatively, you can also check the Advanced setting table for parameters related to Wake on LAN and Waking on "Magic Packets" and enable them.
