Hi, I am currently unable to activate fast user switching in XP-SP2. I have looked through the policies and have enabled all I could find but even though I check the box in "Change the way users log on and off" and click on "Apply," it will not enable. Does the OS take in to account how many limited user accounts there are and how much memory is installed? The computer in question has 384MB with one admin and four limited accounts. Thanks, Darin
