Get-Acl does not seem to work on UNC path? - windows

Question

I have difficulty getting Get-Acl to work on a UNC path to get the share permissions of a directory and all underlying files and directories.
The code I use looks like this:
$OutFile = "C:\Users\xxxx\Desktop\Permissions.csv"
$Header = "Folder Path,IdentityReference,AccessControlType,IsInherited,InheritanceFlags,PropagationFlags,FileSystemRights"
del $OutFile
Add-Content -Value $Header -Path $OutFile
$RootPath = "\\intranet\sites\folder1\folder2\target-folder-as-root"
$Folders = dir $RootPath -Recurse
#| where {$_.psiscontainer -eq $true}-recurse
foreach ($Folder in $Folders) {
$ACLs = Get-Acl $Folder.Fullname | ForEach-Object { $_.Access }
foreach ($ACL in $ACLs) {
$OutInfo = $Folder.Fullname + "," + $ACL.IdentityReference + "," +
$ACL.AccessControlType + "," + $ACL.IsInherited + "," +
$ACL.InheritanceFlags + "," + $ACL.PropagationFlags + "," +
$ACL.FileSystemRights
Add-Content -Value $OutInfo -Path $OutFile
}
}
Not taking into account the filename size limit issue this might cause, I get the following error:
Get-Acl : Method failed with unexpected error code 1.
At C:\Users\xxxx\Documents\ntfs_permissions.ps1:12 char:10
+ $ACLs = Get-Acl $Folder.Fullname | ForEach-Object { $_.Access }

I find documentation on listing the shared permissions on a shared drive using the UNC path (I don't want to list the permissions starting from the root, but only starting from a subfolder) is very limited.

Answer 1

Try to use: $ACLs = (Get-Acl $Folder.fullname).Access
Instead of: $ACLs = Get-Acl $Folder.Fullname | ForEach-Object { $_.Access }
