Server 2008 R2 Powershell version 4 cannot use Get-Net* (anything) commands

Question

Brand new to PS here.
I have a new install of 2008R2 and have updated to Powershell 4 by installing Windows
Management Framework 4.0. The system has DotNET 4.5.1 on it as well.
I am trying to run a script for setting IP which is part of the example shown in the following blog:
http://blogs.technet.com/b/heyscriptingguy/archive/2013/01/03/use-powershell-to-deploy-a-new-active-directory-forest.aspx
So far I have run into a brick wall as I am unable to break the code for using the Get-NetAdapter command.
In the example, the following is shown:
  $ipif = (Get-NetAdapter).ifIndex  New-NetIPAddress -IPAddress $ipaddress -PrefixLength $ipprefix -InterfaceIndex $ipif -DefaultGateway $ipgw
When running the script, PS errors with
"Get-NetAdapter : The term 'Get-NetAdapter' is not recognized as the name of a cmdlet, function, script file, or operable program"
I found that by using "$ipif = Get-Command -Module NetAdapter -InterfaceIndex" , I get nothing. When I use the PowerShell ISE, no error
is given either and the Intellisense feature is no help.
I have executed
Get-Module on my system and this is the output:
ModuleType Version    Name                              
            ExportedCommands

Manifest   3.0.0.0    Microsoft.WSMan.Management             {Connect-WSMan, Disable-WSManCredSSP, Disconnect-WSMan...
Executing the command
$psversiontable returns the following:

PSVersion                      4.0
WSManStackVersion       3.0
SerializationVersion        1.1.0.1

BuildVersion                   6.3.9600.16406
PSCompatibleVersions    {1.0, 2.0, 3.0, 4.0}

I would welcome suggestions, comments and/or pointers for the correct direction in which to travel.
Thanks in advance

Answer 1

another joke from Microsoft...... there are many documents on the TechNet referring to Windows Management Framework 4.0 containing NetAdapter cmdlet... even pointing to the right download location.... but forget to mention that the damn thing does
not work on Windows Server 2008 environment... again... a joke
It's right at the top of the documentation page for the cmdlets.

Perhaps you need to get your eyes checked.
