Wake 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.

Prerequisites for Wake on LAN (WOL)

  1. Either one of the following conditions should be met for Wake on LAN:

    • One of the computers with Desktop Central agent should be alive in the target subnet, to perform Wake on LAN.
    • IP directed broadcast should be enabled on the router/switch

  2. Operating System related Settings:

    Go to Tools, click Wake on LAN, and click Settings. Here, enable Enable Wake On LAN settings in Agent Machines.

  3. BIOS Settings:

    The Wake-On-LAN functionality is generally disabled by default. The procedure to remotely modify the BIOS Settings of the target computers varies from manufacturer to manufacturer. Most manufacturers do not allow remote configuration of the BIOS Settings due to security concerns. However, a few manufacturers like Dell, HP, and Lenovo allow remote configuration. For those manufacturers, please follow the procedure given at the end of this section. For others, where your manufacturer does not allow remote configuration of the BIOS Settings, please follow the Manual Configuration procedure:

    Manually Configuring the BIOS Settings:

    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 Management.
    3. Choose Wake on LAN/WLAN, under Wake on LAN/WLAN, choose LAN or WLAN
    Note: If you see a mode called "Deep Sleep Mode", ensure that it is disabled. This mode may not be found on all computers.
    4. Save and Exit the BIOS settings.

    Remotely configuring the BIOS Settings:

    Dell, Lenovo and HP allow you to modify the BIOS Settings remotely through a specific tool:

    • For Dell:
      1. Dell Client Configuration Utility (DCCU) can modify BIOS Settings remotely for Dell computers. To get the latest driver of DCCU, please visit this link.
      2. Follow the steps given in this document to configure BIOS using DCCU.
    • For HP: HP BIOS Configuration Utility (HPBCU) can modify the BIOS Settings remotely for HP computers. Please visit this link.
    • For Lenovo: Lenovo Think BIOS Config Tool (TBCT) can modify the BIOS Settings remotely for Lenovo computers. Please visit this link.  

Note:When computers running on Windows 10 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 this article: http://support.microsoft.com/kb/2776718 .

 

Waking up computers manually/on-demand

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

  1. From the Tools tab, click Wake On LAN.
  2.  This lists all the managed computers in your network. From this list, select the computers that need to be booted and click Wake Up Now.

 You can see that the wake up process has been initiated and the status will be updated.

Waking up computers automatically/Scheduling a Wake on LAN task

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

Step 1: Define Task

  1. Navigate to Wake on LAN from the Tools tab.
  2. Click the Schedule Wake Up button to create a new task and specify the following:
    • Provide a name for the task
    • Waiting time after wake up: Desktop Central, after broadcasting the Wake On LAN packets, will wait for the period specified here to check the status of the computer.
    • 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. Define the targets that comprise the list of computers to be booted.
  2. Broadcasting of the WOL packets is based on the subnet address of the computers. If the subnet address is blank or if it is incorrect, the task may fail. You can modify the details such as MAC address, IP address and Subnet mask of the computer by choosing Modify under the Actions column opposite to the corresponding computer.

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 their execution history can be verified from the Task Details page.

Viewing and Modifying Wake on LAN Tasks

To view the Wake on LAN tasks that have been created, follow the steps below:

  1. Navigate to Wake on LAN from the Tools tab. This lists all the tasks that are already created/scheduled.
  2. To modify a task, choose to Modify from the Actions column opposite to the corresponding task.
  3. To delete a task, choose to Delete from the Actions column opposite to the corresponding task.

Viewing Wake on LAN Task Status

To view the status of the Wake on LAN tasks that have been created, follow the steps below:

  1. Select Wake on LAN from the Tools tab. This lists all the tasks that are already created/scheduled.
  2. Click on the task name to view the status of the computers in that task.

You can filter to view the details of the computers by filtering status such as Scheduled, Processing, Success, and Failed.
