Function Invoke-WOLWakeComputer {

    <#
 
     .SYNOPSIS
     Send a magic packet to a computer
 
     .DESCRIPTION
     Send a magic packet to a computer using its host name (if saved on the database)
     or MAC address
 
     .PARAMETER ComputerName
     Name of the computer to wake up
 
     .PARAMETER MACAddress
     MAC address of the computer to wake up
 
     .PARAMETER Port
     The port to use to send the magic packet (optional)
 
     .EXAMPLE
     Invoke-WOLWakeComputer -ComputerName LabPC2064
 
     .EXAMPLE
     Invoke-WOLWakeComputer -ComputerName LabPC2064 -Port 9
 
     .EXAMPLE
     Invoke-WOLWakeComputer -MACAddress 00:01:02:AA:BB:CC
 
     .EXAMPLE
     Invoke-WOLWakeComputer -ComputerName LabPC2064 -MACAddress 00:01:02:AA:BB:CC
 
     .NOTES
     A combination of computer names and MAC addresses can be used, the magic packet
     will be sent individually
