<#
.SYNOPSIS
    Executes a specified PowerShell script on a list of remote servers.
    GitHub Repository: https://github.com/roalhelm/

.DESCRIPTION
    This script reads a list of server names from a file and executes a specified 
    PowerShell script on each server. The script uses the provided credentials to 
    establish a remote connection to each server in the list and runs the script 
    in the specified path on each remote server. 

    For each server, it outputs whether the execution was successful or if there 
    was an error. This is useful for performing batch operations across multiple 
    servers from a central location.

.PARAMETER serverListPath
    Path to the file containing the list of server names.

.PARAMETER remoteScriptPath
    Path to the PowerShell script to be executed remotely on each server.

.NOTES
    Script requires the necessary permissions to connect to the remote servers.
    Each server in the server list must allow PowerShell Remoting.
