Wake on LAN

The Wake on LAN Tool of Desktop Central MSP 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 MSP 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 MSP agents which are live in that subnet. Desktop Central MSP 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 should have a live Desktop Central MSP agent to perform the wake up task.

If you try to wake a computer which belongs to a remote  office, then one of the following criteria should be met:

  1. IP redirected broadcast should be enabled on the router
  2. One of the computer with Desktop Central agent should be live in the same subnet, to perform the task.

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

  1. From Tools tab, click Wake On LAN.
  2. This lists all the managed computers in the network. From this list, select the computers that need to be booted and click Wake Up Now.
  3. You can see that the wake up process has been initiated and the status will be updated.

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 this article: http://support.microsoft.com/kb/2776718 .

Step 2: Select Computers

    1. Define the targets that comprise of the list of computers to be booted.

    2. Broadcasting of the WOL packtes 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 to Modify from under Actions column against the corresponding computer.
