I am looking for a solution to convert the Dell Service Tag to the Express Service Tag, I found a php solution here:
http://www.wlscripting.com/tutorial/35

gives a breakdown on how it's done and the script. I converted the php to asp using:
http://www.me-u.com/php-asp/hosting/asp.php

I am using bginfo v4.0 to record data for all my workstations in a xls spreadsheet, i have all the info, the only object i cannot get is the conversion.
you get the service tag number from:

SELECT SerialNumber FROM Win32_BIOS

Any help would be GREAT!
