# Script

Clear-Host
$ADServer ="Server1"
$GetGroup = $true;

if($GetGroup -eq $true) 
{
 $groups = Get-ADGroup -Server $ADServer -Properties  *  -filter {GroupCategory -eq "Security" -and GroupScope -eq "Global"}  
  
foreach ($group in $groups)
 { $count++
 
 $Group = $group.Name
      $Name = $group.Name
      $ManagedBy = $group.ManagedBy
      $whenChanged = $group.whenChanged
      $whenCreated = $group.whenCreated
      $uSNChanged = $group.uSNChanged
      $GroupCategory = $group.GroupCategory
      $GroupScope = $group.GroupScope
      $Description = $group.Description

               Write-host 'Group = '   $Group
