.SYNOPSIS 
    Function New-LabCert creates a selfsigned computercertificate for lab environments
.DESCRIPTION 
    This script creates a selfsigned computercertificate for lab environments. It is stored in cert:\localmachine\my
    and from there it is exported as a pfx-file to c:\. This file then gets imported in 'Trusted Roots' to make it trustworthy.
    Finally some cleanup is performed, e.g. the pfx-file will be deleted.
    Please consider to run it with the -verbose parameter to receive some informative output.
.PARAMETER DNSName
    This is the only but mandatory parameter. Please enter the DNSHostname of the machine you want this certificate for.

.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.

      .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.
