I have attached a file that allows you to make up a "key disk" for multiple users on one machine.
My wife had multiple telefinder users on one machine. She needed a way to make it easy for each one to log on under their own account (they were having trouble remembering name and password). Kris Yates at Worldspice (see below) wrote a bat file that when loaded, erases the tfuser.ini from the windows dir on C: and copies the tfuser.ini on disk to C: drive. The tfuser.ini on the disk is for one person and contains their logon name and password. Each person has their own "key disk".
Name the .bat file "Load me first" and that helps your users remember to do it first! Place in the telefinder folder to make it easy to find. When preparing the .ini disks, edit the .ini file for each user (be sure to check the phone number).
Much thanks to Kris Yates from WorldSpice (my local ISP).
