You can disable a specific network adapter or even all network adapters using Windows PowerShell. For example, the following command disables the adapter named “Ethernet 2” with no confirmation prompt displayed:
PS C:\> Disable-NetAdapter -Name "Ethernet 2" -Confirm:$false
To disable all network adapters on the server, you can use this command:
PS C:\> Disable-NetAdapter -Name *
Note that all remote connectivity with the server will be lost if you do this.
To enable any network adapters that are disabled, you can use the Enable-NetAdapter cmdlet.

This tip is dated June 2013 and if you google “powershell versions” you’ll see that PowerShell 4.0 was introduced in October 2013, so this tip applies to PowerShell 3.0 which was included with Windows 8 and Windows Server 2012.
