Last logon time

On certain occasions, we are required to find when a user successfully logs on to a domain. This can be for audit purposes or for troubleshooting purposes:

$username = Read-Host 'What is the User account you looking for ?' 
   $dcs = Get-ADDomainController -Filter {Name -like "*"} 
      foreach($dc in $dcs) 
   {  
     $hostname = $dc.HostName 
     $user = Get-ADUser $userName -Server $hostname -Properties lastLogon 
     $lngexpires = $user.lastLogon 
     if (-not ($lngexpires)) {$lngexpires = 0 } 
     If (($lngexpires -eq 0) -or ($lngexpires -gt [DateTime]::MaxValue.Ticks)) 
     { 
       $LastLogon = "User Never Logged In" 
     } 
      Else 
     { 
       $Date = [DateTime]$lngexpires 
       $LastLogon = $Date.AddYears(1600).ToLocalTime() 
     } 
  } 
  Write-Host $username "last logged on at:" $LastLogon

The preceding script will ask for the username of the account and, once it is provided, the system...
