I don't really have the expertise in batch scripting to help with that. BUT...if you wanted to move the webpage code into the Kix script, then the following kix code will open multiple pages.

 Code:
$objExplorer = CreateObject("InternetExplorer.Application")
$objExplorer.Navigate2("https://www.google.com", 0)
$objExplorer.Navigate2("http://www.kixtart.org/forums/ubbthreads.php?ubb=cfrm", 2048)
$objExplorer.Visible = 1
