Get Active Directory Group Members with PowerShell

I’ve not blogged for quite a while. Let’s come back with a small PowerShell script for retrieving Active Directory Group Members.

The bellow scripts retrieve all the Active Directory groups in a specific OU and count the number of members.

Import-Module ActiveDirectory

$groups = Get-ADGroup -searchbase "OU=MyOU,DC=myDC,DC=net" -filter *

$myArray = @()

foreach($g in $groups)

{

                $members = Get-ADGroupMember($g)

                $myObject = New-Object System.Object

                $myObject | Add-Member -type NoteProperty -name Name -Value $g.Name

                $myObject | Add-Member -type NoteProperty -name Count -Value $members.Length
            
$myArray += $myObject

}

$myArray

PowerGUI Error : Microsoft SharePoint is not supported with version 4.0.30319.1 of the Microsoft .Net Runtime

I’m used to work with PowerGUI script editor for developing Powershell scripts for SharePoint 2010. This time, after updating PowerGUI with version 3.2.0.2237 and running a SharePoint cmdlet, I got this error:

“Microsoft SharePoint is not supported with version 4.0.30319.1 of the Microsoft .Net Runtime."

After investigations, this issue is caused by PowerGUI itself. To fix it, open the ScriptEditor.exe.config file placed in the PowerGUI installation directory. Remove of comment this line:

Restart the script editor and everything works again !

How to add SharePoint snapin to Power GUI script editor

1. Open Power GUI script editor

2. Select: Microsoft.SharePoint.PowerShell

3. Now, you can use PowerShell intellisense on SharePoint module !

Start/Stop a SharePoint 2010 Service Application

Sometimes, it can be useful and more efficient to handle Sharepoint Service applications using Powershell.
The following script can be used for starting or stopping a service application instance.

A Sharepoint Service application is running behind a service application instance. This instance represents the service application on the whole Sharepoint Farm.
Stopping the instance will stop the related service application on all the servers in the farm.

First of all, we need to get all the service instances running on the farm:

Get-SPServiceInstance

From the list, select your service instance GUID and copy it.
For stopping the service instance, you just need now to run the Stop-SPServiceInstance command:

Stop-SPServiceInstance -Identity "YourServiceGUID"

Type "Y" when prompted.

Start-SPServiceInstance can be used using the same manner for starting the service again.

Attach Visual Studio to an application using Powershell

This script can be used to run the Visual Studio just in time debugger for debugging your website. It gets the name of the application pool running the website and then attach the JIT to the w3wp process.

$filter = "*MyWebsite*"

$w3wp = get-WmiObject Win32_Process -Filter "Name='w3wp.exe'"
$prid = $w3wp | where { $_.CommandLine -like $filter }

c:\Windows\System32\vsjitdebugger.exe -p $prid.ProcessId

Remove duplicates using Powershell

This is a quick powershell script for removing duplicates files from a folder.
I used it for removing duplicates from my music library.

It is simply listing all the duplicates files from a directory and copy them to a back up folder.

$musicFolder = "c:\MyFolder"
$backupFolder = "c:\Backup"

echo "Get duplicates"
$dupmusics = ls $musicFolder -recurse | Group-Object Length, LastWriteTime | Where { $_.Count -gt 1 }

if($dupmusics.Length -gt 0)
{
echo "Move duplicates"
$dupmusics = $dupmusics | ForEach-Object { $_.Group[1..$_.Group.Count] } | Move-Item -Destination $backupFolder -Verbose
}
else
{
echo "no duplicates found"
}
