Powershell – Liste des partages réseau sur un serveur de fichier avec détails

3 décembre 20193 décembre 2019 par Antoine Delrue

Hello, Un petit script permettant de lister tous les shared folders sur un serveur de fichier Microsoft, et de générer un fichier CSV et HTML avec les détails. Utile pour avoir une vue globale de l’utilisation des ressources par share, ou pour inventaire.

# Reset the variables to start with something clean
$array = $allShares = $count = $objFldr = $counter = $share = $body = $outCSV = $outHTML = $null

# This is the Windows file server (EDIT THIS)
$fileServer = "fs01.domain.com"

# This variable will contain all shared folders hosted on the File Server
$allShares = Get-WmiObject Win32_Share -ComputerName $fileServer | select Caption, Name, Path

# Counting how many shares are hosted on that server
$count = $allShares.count

# Creating an object that will be used to get fodler sizes later
$objFldr = New-Object -com Scripting.FileSystemObject

# Creating an empty array that will be populated with our findings
$array = @()

# Starting a counter, just for console logging
[int]$counter = "0"

foreach ($share in $allShares)
{
    Write-host "Now processing share number $counter on a total of $count shares."

    $shareName = $share.Name # Get the share name
    $shareCaption = $share.Caption # Get the share caption (decription)
    $sharePath = "$fileServer" + $share.Path # Construct the share path

Bonjour, Ci-après un script qui permet de lister, pour les utilisateurs d’un groupe, la date à laquelle le mot de passe a été changé pour la dernière fois, la date d’expiration du mot de passe, ainsi que la politique ( password policy) appliquée.
