which works great Windows 2012 onwards, i am looking to run this query against Windows 2008 R2 servers.

Answer 1

I got this working on a Windows 2008 server, using a .NET class, cast to an object in powershell, Sample code as follows:

    $nlm = [Activator]::CreateInstance([Type]::GetTypeFromCLSID([Guid]"{DCB00C01-570F-4A9B-8D69-199FDBA5723B}"))
    $nlm.GetNetworkConnections() | ForEach-Object { 
                                    [PSCustomObject]@{
                                    NetworkName = ($_.GetNetwork().GetName());
                                    isConnectedToInternet = $_.isConnectedToInternet;
                                   } 
    if ($nlm.IsConnectedToInternet)
            {
                $NLAState = 'Internet'
            }
            "Access type : $NLAState"
