Get process owner from AD - powershell

Question

I am using Powershell on Windows Server 2008 R2 and I need any regular user get owner of the process with name and surname from AD.
Here's script wrote with help of Mathias R. Jessen
Import-Module ActiveDirectory
$ProcessWithOwners = Get-WmiObject Win32_Process -Filter 'Name LIKE "vr[0-9]%"' |Select *,#{Name="Owner";Expression={$_.GetOwner().User}}
foreach($Process in $ProcessWithOwners)
{
$Username = $Process.Owner
$ADUser = Get-ADUser -Filter "SamAccountName -eq '$Username'" -properties *
$a = new-object -comobject wscript.shell
$b = $a.popup(“Process name $($Process.Name) is run by user $($ADUser.DisplayName)“,0,“Warning”,1)
}
But regular user can't get access to process's owner.
Is there any way to solve it?
* Final Update *
For running this script as regular user I made some changes:
Import-Module ActiveDirectory
Add-Type -Name win -MemberDefinition '[DllImport("user32.dll")] public static extern bool ShowWindow(int handle, int state);' -Namespace native
[native.win]::ShowWindow(([System.Diagnostics.Process]::GetCurrentProcess() | Get-Process).MainWindowHandle,0)
$ConsProcess = Get-WmiObject Win32_Process -Filter 'Name LIKE "vr[0-9]%"' | Select *,#{Name="Owner";Expression={$_.GetOwner().User}}
if ($ConsProcess -ne $null) {
foreach($Process in $ConsProcess)
{
$QueryProcess = query process $Process.ProcessName
$Id = ($QueryProcess[1] -replace ' +',' ').Trim().Split(' ')[2]
$QueryUser = query session $Id
$User = ($QueryUser[1] -replace ' +',' ').Trim().Split(' ')[1]
$ADUser = (Get-ADUser -Identity $User -Properties *).DisplayName
$a = new-object -comobject wscript.shell
$b = $a.popup(“Консультант запущен с именем $($Process.Name) пользователем $($ADUser)“,0,“Внимание”,1)
}
}
else
{
& 'D:\consultantplus\cons.exe' /adm /inet
}

There's no reason to call both gwmi Win32_Process and Get-Process when all you need is just the Owner.
You can do with just:
$CmdProcessWithOwners = Get-WmiObject Win32_Process -Filter 'Name LIKE "cmd%"' |Select *,#{Name="Owner";Expression={$_.GetOwner()}}
Since you could potentially find more than one process matching your criteria, you might want to iterate over the process(es) in a loop:
foreach($Process in $CmdProcessWithOwners)
{
# Grab the user name we added earlier
$Username = $Process.Owner.User
$Domain = $Process.Owner.Domain
$DisplayName = switch($Domain)
{
'DOMAINNAME' {
# Process owned by AD User, grab name from AD
Get-ADUser -Filter "SamAccountName -eq '$Username'" -Properties DisplayName |Select-Object -ExpandProperty DisplayName
}
$env:ComputerName {
# Process owned by local user, look up local account full name
[adsi]"WinNT://$($env:ComputerName)/$Username,user" |Select-Object -ExpandProperty FullName
}
default {
# Likely system or virtual account, default to DOMAIN\Username
"$Domain\$Username"
}
}
# Print it
Write-Host "Process $($Process.Name) with ID $($Process.Id) belongs to $DisplayName"
}
