.SYNOPSIS
    Function New-LabNCSI configures a server as IIS and DNS to support
    Network Connectivity Status Indicator (NCSI) scenarios for lab environments.
.DESCRIPTION
    In some lab environments some machines really need to think they're on the internet,
    e.g. a Direct Access scenario. Most of my labs won't have internet access b/c I like to keep the VMs "sandboxed".
    This function helps you to turn a machine into a IIS- and DNS-
    Server simulating Microsofts Network Connectivity Status Indicator technique.
    To avoid touching the registry of the clients that will use this machine, the default MS

      .SYNOPSIS
      Script to install and configure a standalone RootCA for Lab-Environments
      .DESCRIPTION
      This Script sets up a standalone RootCA. It's main purpose is to save time when building Labs in the classes I teach.
      ###It's not meant for production!###
      First, it creates a CAPolicy.inf file. Then it deletes all default CDP and AIA and configures new ones.
      It turns on auditing and copys (It's a Lab!!!, so obviously no real offline RootCA...) the crt and crl to an edge webserver.

.SYNOPSIS
    The Function Export-MyVM extends the standard cmdlet Export-VM with dynamic parameters.
.DESCRIPTION
    The Script makes the search for the VMs and the Export-Destination-Drive dynamic.
    You can simply tab through the two mandatory parameters to get (a) all VMs on the Hyper-V-Host and (b) all connected drives.
    Frankly, the main purpose was to learn dynamic parameters.
.PARAMETER VMName
    Tab out all VMs on the Hyper-V-Host.
    It's a positional (1) and mandatory parameter.
