Determining a User's Last Logon Time

Determining a User's Last Logon Time

This topic explains how to use the Active Directory module for Windows PowerShell to determine the last time that a user logged on to the system.

Example

The following example is a sample script that you can use to find the last logon time of the user SaraDavis:

C#

Import-Module ActiveDirectory

function Get-ADUserLastLogon([string]$userName)
{
  $dcs = Get-ADDomainController -Filter {Name -like "*"}
  $time = 0
  foreach($dc in $dcs)
  { 
    $hostname = $dc.HostName
    $user = Get-ADUser $userName | Get-ADObject -Properties lastLogon 
    if($user.LastLogon -gt $time) 
    {
      $time = $user.LastLogon
    }
  }
  $dt = [DateTime]::FromFileTime($time)
  Write-Host $username "last logged on at:" $dt }

Get-ADUserLastLogon -UserName SaraDavis

A script is a series of Active Directory module cmdlets. For more information about running Active Directory module scripts, see Running Windows PowerShell Scripts (http://go.microsoft.com/fwlink/?LinkID=119588).
