The Powershell Command "Get-DistributionGroup" doesn't work
<p>The <code>Get-DistributionGroup</code> command is supposed to list distribution groups in a domain but I can't get it to run on my server.</p>

<p>After some Googling I found that <code>Import-Module ActiveDirectory</code> needs to be run first, but what I get when I run that is:</p>

<blockquote>
  <p>Import-Module : The specified module 'ActiveDirectory' was not loaded because no valid module file was found in any module directory.</p>
</blockquote>

<p>My questions are </p>

<ol>
<li>How do I install this module into my PowerShell module directory? I thought it was supposed to do this automatically</li>
<li>Once I have it installed, do I just run <code>Import-Module ActiveDirectory</code> and then I can run <code>Get-DistributionGroup</code> to list my dist groups?</li>
</ol>
