Hi, John.

Microsoft ships a module called ActiveDirectory as either part of the RSAT tools for Windows clients, or as part of Windows Server via the feature named "RSAT-AD-PowerShell".

If that ActiveDirectory module is installed (which it almost certainly will be by default on a domain controller, but may not be on anything that's not a domain controller) then you simply need to import the ActiveDirectory module prior to calling any of the functions you're defining.

Import-Module -Name ActiveDirectory;

Example

There are other ways but this is the most practical (without diverging into why).

Cheers,
