PowerShell script to test network connections at customer sites to determine if the whitelist is okay.

To convert this PowerShell script into an executable (.exe) file, you can still use PS2EXE as described before:

1. Install PS2EXE (if you haven’t already):

   Install-Module -Name ps2exe

2. Convert the script to an executable:

   Invoke-ps2exe .\ping_websites.ps1 .\ping_websites.exe

This will create an executable file named ping_websites.exe that you can run on any Windows machine. When run, it will open a file dialog for the user to select the whitelist file, then proceed with pinging the websites and generating the report.
