One of the questions in the recent Scripting Games involved toggling between a wireless and LAN connection. Only one was to be up at any one time.

This can be solved using WMI but becomes hugely simpler in Windows 8/2012 as we get a bunch of cmdlets for working with network adapters.

Using WMI

Get-WmiObject -Class Win32_NetworkAdapter | Measure-Object

I get 15 objects returned on my system – but I’m only interested in 2 of them!

Using the new functionality

PS> Get-NetAdapter | ft -a Name, ifIndex, Status

Name             ifIndex Status
—-             ——- ——
Virtual Wireless      21 Disabled
Virtual LAN           12 Up

This leads to a simple piece of code

Get-NetAdapter |
foreach {
  $nic = $_
  switch ($_.Status){
   "Up"        {Disable-NetAdapter -InputObject $nic -Confirm:$false}
   "Disabled"  {Enable-NetAdapter -InputObject $nic -Confirm:$false}


Get the adapter, test its status and toggle to the other.

These cmdlets are in the NetAdapter module which is created using the cmdlets over objects techniques to utilise WMI classes in a much friendlier way. Remoting capabilities are supplied by CIMsessions

A question came up on Tuesdays UK PowerShell Group session about using the Windows 2012 Active Directory module. The recording links are here


The question asked if the new Site, Subnet and Site link cmdlets would work in a legacy environment.

This morning I installed a Windows Server 2012 Release Candidate member server into my Windows 2008 R2 domain. I then installed the RSAT feature on the Windows 2012 server – this includes the Active Directory module.

The site, subnet and site link cmdlets appear to work with NO changes required to the Windows 2008 R2 domain controller. I was able to view and create sites, subnets and site links.

I haven’t tested any other scenario.

This post shows how to use PowerShell in Windows Server 2012 to configure scheduled tasks that apply across the whole cluster not just a single node

The sessions for the next few months are:

  • 27 March – PowerShell v3 CIM cmdlets and “cmlets over objects”
  • April – Managing Windows Server 8 with PowerShell
  • May – Managing Windows Server 8 with PowerShell

No thats not a mistake – there is so much new PowerShell functionality in Windows server 8 that two sessions will just scratch the surface.  I’m delivering the April session and PowerShell MVP Jonathan Medd is delivering the May session.

Creating a new AD forest

Posted by: | March 11, 2012 | No Comment |

One big change with Windows Server 8 is that dcpromo is no more – its gone, gone gone.

Instead the promotion wizard is started from Server Manager. Install the AD Domain Services role and you will see a notification at the top right of the Server Manager console with a complete Active Directory configuration option.  Click that and the wizard starts. If you’ve used dcpromo on earlier versions of Windows there won’t be any surprises.

Best of all you get the PowerShell commands to do the job

Import-Module ADDSDeployment
Install-ADDSForest `
-CreateDNSDelegation:$false `
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "Win8" `
-DomainName "Beta8.test" `
-DomainNetBIOSName "BETA8" `
-ForestMode "Win8" `
-InstallDNS:$true `
-LogPath "C:\Windows\NTDS" `
-RebootOnCompletion:$true `
-SYSVOLPath "C:\Windows\SYSVOL" `

already to be re-used.  The AD Administrative Centre also produces the PowerShell it uses under the hood but thats a story for another day.

The ADDSDeployment module has a number of cmdlets

PS> Get-Command -Module ADDSDeployment

Capability      Name
———-      —-
Cmdlet          Add-ADDSReadOnlyDomainControllerAccount
Cmdlet          Install-ADDSDomain
Cmdlet          Install-ADDSDomainController
Cmdlet          Install-ADDSForest
Cmdlet          Test-ADDSDomainControllerInstallation
Cmdlet          Test-ADDSDomainControllerUninstallation
Cmdlet          Test-ADDSDomainInstallation
Cmdlet          Test-ADDSForestInstallation
Cmdlet          Test-ADDSReadOnlyDomainControllerAccountCreation
Cmdlet          Uninstall-ADDSDomainController


I’ll be trying out the Install-ADDSDomainController soon
