   Would you happen to know how to retrieve the users logged on to a domain?

   [...] Hugo Peeters has a great function for using WMI to get Logged on Users: http://www.peetersonline.nl/index.php/powershell/oneliner-get-logged-on-users-with-powershell/ [...]

   Hugo,

   your script is almost working

   can only give me the following result:

   Laptop425SYSTEM
   Laptop425LOCAL SERVICE
   Laptop425NETWORK SERVICE
   MYDOMAINusername
   Laptop425ANONYMOUS LOGON

   how to get MYDOMAIN\username only ?

   I’ve just made a little change in the script to add the computername.
   You can now use it with a server list as well as a single server.

   
function Get-MyLoggedOnUsers
{
param([Array]$Computer)
Get-WmiObject Win32_LoggedOnUser -ComputerName $Computer |
Select __SERVER, Antecedent -Unique |
%{"{0} : {1}\{2}" -f $_.__SERVER, $_.Antecedent.ToString().Split('"')[1], $_.Antecedent.ToString().Split('"')[3]}
}


   
Get-MyLoggedOnUsers localhost

   or

   Get-MyLoggedOnUsers Server1

   or

   $Server_List = ("Server1","Server2","Server3")
Get-MyLoggedOnUsers $Server_List

   Yours, combined with

   and
   http://forums.techarena.in/software-development/1118294.htm
   
function get-loggedonusers
{
param([Array]$Computer)
$computers = get-wmiobject Win32_Computersystem -computername $Computer
$report = @()
foreach ($c in $computers) {
$temp = "" | Select Computer, Username
$temp.Computer = $c.name
$temp.Username = $c.username
$report += $temp
}#foreach
$report
}#function


   Dump anything else from http://msdn.microsoft.com/en-us/library/windows/desktop/aa394102(v=vs.85).aspx in there if needed.

   Thanks for your method.

   To output the current username by itself, use:

   function Get-LoggedOnUsers {
   $Computers = HOSTNAME
   $Computers | foreach {$((Get-WmiObject Win32_ComputerSystem | Select UserName | Format-Table -HideTableHeaders | Out-String) -split ‘\\’)[1]}
   }

   Get-LoggedOnUsers

   To output the username as DOMAIN\username, use:

   function Get-LoggedOnUsers {
   $Computers = HOSTNAME
   $Computers | foreach {$(Get-WmiObject Win32_ComputerSystem | Select UserName | Format-Table -HideTableHeaders | Out-String)}
   }

   Get-LoggedOnUsers

   Hope this helps
