.SYNOPSIS
A script to restart automatic services on remote VMs and send an email report.

.DESCRIPTION
This script imports a CSV file that contains a list of VM names and another CSV file that contains AD credentials.
It loops through each VM name and checks if it has any stopped automatic services.
If yes, it restarts the services and collects the status results.
If no, it collects the status results.
It outputs the service status for each VM to an HTML file with a beach background and a dragon, sword and phoenix frame.
It sends an email with the HTML file and the log file as attachments to a specified address.

.PARAMETER VMList
The path to the CSV file that contains the VM names.

.PARAMETER CredentialList
The path to the CSV file that contains the AD credentials.

.PARAMETER EmailList
The path to the CSV file that contains the email addresses.

.INPUTS
None

.OUTPUTS
An HTML file stored in C:\Windows\Temp\VMReport.html
A log file stored in C:\Windows\Temp\RestartServices.log
