Network Adapter details

In this post - http://msmvps.com/blogs/richardsiddaway/archive/2011/07/09/linking-the-network-card-to-the-registry-settings.aspx – I showed how to get the NetLuidIndex by linking the network card to the matching registry settings.  There is another way to get some that same information.

function get-adapter {            
param(            
 [string]$computer="."            
)            
Get-WmiObject -Namespace root\wmi -Class MSNdis_EnumerateAdapter `
-ComputerName $computer |            
foreach {            
 $nic = Get-WmiObject -Namespace root\wmi -Class MSNdis_EnumerateAdapterEx `
-ComputerName $computer -Filter "InstanceName = '$($_.InstanceName)'"            
            
$header = $nic.EnumerateAdapter.Header            
            
 New-Object -TypeName PSobject -Property @{            
  Computer = $_.__SERVER            
  Adapter = $_.InstanceName            
  Device = $_.DeviceName            
  Active = $_.Active            
  Index = $($nic.EnumerateAdapter.IfIndex)            
  NetLuid = $($nic.EnumerateAdapter.NetLuid)            
  Revision = $header.Revision            
  Size = $header.Size            
  Type = $header.Type            
 }            
}            
}

Use the MSNdis_EnumerateAdapter  class to get the adapters and match to the MSNdis_EnumerateAdapterEx  class on the Instance name. Not sure what size and type signify but they are identical on all adapters on my Windows 7 machines.

NOTE: The Index property is NOT the same as the DeviceId/Index property on the Win32_NetworkAdapter\Win32_NetworkAdapterConfiguration classes.
