This powershell function is not mine, but I kept it as I found it useful from time to time.

function Send-WOL
{
<# 
  .SYNOPSIS  
    Send a WOL packet to a broadcast address
  .PARAMETER mac
   The MAC address of the device that need to wake up

  .EXAMPLE 
   Send-WOL -mac 00:11:32:21:2D:11 -ip 192.168.8.255 
#>
 
[CmdletBinding()]
param(
[Parameter(Mandatory=$True,Position=1)]
[string]$mac,
[string]$ip="255.255.255.255", 
[int]$port=9
)
$broadcast = [Net.IPAddress]::Parse($ip)
  
$mac=(($mac.replace(":","")).replace("-","")).replace(".","")
$target=0,2,4,6,8,10 | % {[convert]::ToByte($mac.substring($_,2),16)}
$packet = (,[byte]255 * 6) + ($target * 16)
  
$UDPclient = new-Object System.Net.Sockets.UdpClient
$UDPclient.Connect($broadcast,$port)
[void]$UDPclient.Send($packet, 102)

Remove unused PNP drivers from system.

This will remove drivers of working, but disconnected devices. (e.g. USB Drives Printers, old video devices, etc).

FOR /L %G in (1,1,999) do PnPutil.exe -D oem%G.inf

For further cleanup: I recommend Device Cleanup Tool from Uwe Sieber. You can get it from their website.

$username = "user@domain.com"
$password = "mypassword"
$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr
$errorCount = 0
foreach($Event in $logs)
{
$Errorlevel=$Event.LevelDisplayName
    if ($Errorlevel -eq "Error")
        {
        $errorCount++
        }
}

Send Windows Event Logs as an e-mail. (PowerShell)

This script can be used to send windows event logs on period basis to specific e-mail. Below example sending last 24 hours of events in the Windows Essential Licensing section.

$Yesterday = (Get-Date) - (New-TimeSpan -Day 1)
$logs = Get-WinEvent -LogName "Microsoft-Windows-Server Infrastructure Licensing/Operational" | Where-Object {$_.TimeCreated -ge $Yesterday} | Format-List | Out-String
$username = "user@domain.com"
$password = "mypassword"
$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr
#Send-MailMessage [-Attachments ] [-Bcc ] [[-Body] ] [-BodyAsHtml]
# [-Encoding ] [-Cc ] [-DeliveryNotificationOption ]
# -From  [[-SmtpServer] ] [-Priority ] [-Subject]  [-To] 
# [-Credential ] [-UseSsl] [-Port ] []
Send-MailMessage -Body $logs `
-From me@domain.com `
-SmtpServer mail.server.com `
-Subject "Licensing Logs" `

Mapping iSCSI disks in VirtualBox

To add iSCSI disk to already made VirtualBox machine do the following from a terminal/Command Prompt
VBoxManage storageattach MyVirtualMachineNameOrUUID --storagectl "SATA" --port 0 --device 0 --type hdd --medium iscsi --server 10.10.10.7 --target "iqn.2004-04.com.nas:target-name" --tport 3260

MyVirtualMachineNameOrUUID = The Name of your Virtual Machine. Use quotes if your VM name has spaces
–storagectl “SATA” = Name of the controller under the storage tab in VirtualBox
–port 0 = Port Number. If you already created a virtual disk connected to the SATA controller, probably want to select a different virtual sata port.
–server 10.10.10.7 = ip address of the iSCSI server
–target “iqn.2004-04.com.nas:target-name” = Full target name
–tport 3260 = iSCSI server port number.
