Powershell File Sharing Permissions Report

Often I am asked to verify folder permissions for a user in a specific place out on one of our servers. Typically this requires browsing out the folder and putting eyes on the permissions dialog box looking for a group on which the user is a member and then documenting it in the ticket. A very painful long boring process. This is where Powershell comes and saves the day. I wrote a very simple script to bring that information to me. It also gives nice output that I can directly copy into tickets to answer what groups has rights to what shares.

This prompts the user to “Enter a UNC Path” once entered goes and grabs the NTFS permissions as well as the SMB Share permissions

Powershell Code


$path = Read-host “Enter a UNC Path: ”
$pathparts = $path.split("\")
$ComputerName = $pathparts[2]
$ShareName = $pathparts[3]

Write-Host "File Sharing Permissions Report - $path"

$acl = Get-Acl $path

Write-Host "File/NTFS Permissions"

foreach($accessRule in $acl.Access)
    Write-Host "   " $accessRule.IdentityReference $accessRule.FileSystemRights
Write-Host "Share/SMB Permissions"

    $Share = Get-WmiObject win32_LogicalShareSecuritySetting -Filter "name='$ShareName'" -ComputerName $ComputerName
        $obj = @()
        $ACLS = $Share.GetSecurityDescriptor().Descriptor.DACL
        foreach($ACL in $ACLS){
            $User = $ACL.Trustee.Name
            if(!($user)){$user = $ACL.Trustee.SID}
            $Domain = $ACL.Trustee.Domain
                2032127 {$Perm = "Full Control"}
                1245631 {$Perm = "Change"}
                1179817 {$Perm = "Read"}
            Write-Host "   $Domain\$user  $Perm"
