Toggling between LAN and Wireless
Published June 2, 2012One 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

Leave a commentUsing Windows 2012 Active Directory module in a Windows 2008 R2 domain
Published June 2, 2012A 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.

Up coming User group sessions
Published March 16, 2012The 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.
Details on March’s sessions from
http://msmvps.com/blogs/richardsiddaway/archive/2012/03/06/uk-powershell-group-march-2012.aspx
As always the session will be recorded and made available afterwards.
Creating a new AD forest
Published March 11, 2012One 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:$true `
-SYSVOLPath "C:\Windows\SYSVOL" `
-Force:$true
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 Test-ADDSDomainControllerUninstallation
Cmdlet Test-ADDSDomainInstallation

I’ll be trying out the Install-ADDSDomainController soon
