Importing NTFSSecurity module from UNC path fails

Question

I've created a central repository for Powershell modules, but I'm having trouble loading one in particular. The NTFSSecurity module is failing to import with the following message.

PS Z:\> Import-Module NTFSSecurity
Add-Type : Could not load file or assembly 'file://\\fs\PowerShellModules\NTFSSecurity\Security2.dll' or one of its

I'm running Windows Managment Foundation 3.0 Beta, which includes PowerShell 3.0. I have a feeling that the new security measures introduced in .NET 4.0 are playing a part in this, but running Powershell.exe with the -version 2.0 switch doesn't fix anything either. I have modified my powershell.exe.config files in both the system32 and SysWOW64 folders to the following.

<?xml version="1.0"?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0.30319"/>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
    <runtime>
        <loadfromremotesources enabled="true"/>
    </runtime>
</configuration>

The files are not "blocked", I've checked each one individually (as well as run Unblock-File on the directory). Permissions from the server end are fine, I've verified that I have access to everything. What have I not checked?

Answer 1

It might be a corrupt file/bad download.

I was receiving the same error when trying to load the module from one of my scripts. I went and re-downloaded the newer v2.3 and extracted it into my Powershell Modules folder (C:\windows\system32\WindowsPowershell\v1.0\Modules\NTFSSecurity).

This solved my problem.

Answer 2

Rather than load the module directly from a share, I tend to have a function that copies it locally (this can be adjusted to look for newer versions as well). I suppose this could be written in-line, but I made it a function as part of my 'common modules' that I load.

Function Import-NTFSModule {
   $NTModule = 'C:\Windows\System32\WindowsPowershell\v1.0\Modules\NTFSSecurity'
   $NTSource = '\\servername.fqdn\sharename\Modules\NTFSSecurity'
   If (!(Get-Module -Name NTFSSecurity)) {
      If (!(Test-Path -Path $NTModule) -and (Test-Path $NTSource)) { Copy-Item $NTSource -Destination "$NTModule\" -Recurse -Force }
   }
}

Answer 3

By default, the .ZIP file you download is blocked from being executed. Right-click it and choose "Unblock" before you unpack it, and the files beneath will be unblocked as well.

Sorry that when I originally posted, I didn't see that you said you had unblocked it. I only got the error (identical error code) while the files were in a blocked state.

Answer 4

Run the Import-Module NTFSSecurity from Windows Powershell (not the ISE)
