[powershell] The term 'Get-ADUser' is not recognized as the name of a cmdlet

Check here for how to add the activedirectory module if not there by default. This can be done on any machine and then it will allow you to access your active directory "domain control" server.

EDIT

To prevent problems with stale links (I have found MSDN blogs to disappear for no reason in the past), in essence for Windows 7 you need to download and install Remote Server Administration Tools (KB958830). After installing do the following steps:

  • Open Control Panel -> Programs and Features -> Turn On/Off Windows Features
  • Find "Remote Server Administration Tools" and expand it
  • Find "Role Administration Tools" and expand it
  • Find "AD DS And AD LDS Tools" and expand it
  • Check the box next to "Active Directory Module For Windows PowerShell".
  • Click OK and allow Windows to install the feature

Windows server editions should already be OK but if not you need to download and install the Active Directory Management Gateway Service. If any of these links should stop working, you should still be able search for the KB article or download names and find them.
