I'm having a strange problem; fast user swtiching worked great for the longest time, but just recently it has stopped. When I try to switch users, the screen seems to flicker as if it's trying to go to the welcome screen, but then it doesn't take me anywhere. Whenever I try to change the way users log on/off, I put a check mark next to Allow Fast User Switching and click apply options. However, it won't save my settings. If I go back the same screen, the check mark is gone again.
I've tried changing this in the services part of the control panel by setting it to both manual and automatic--it still doesn't work. Whenever I try to manually invoke it from the Services section of the control panel, I get an error saying that "Fast User Switching Compatibilty could not be started on this local machine"--or something very similar to that.
I've heard PC Anywhere or belonging to a domain can screw things up, but neither of these apply to me. I've tried running SFC /scannow to replace any broken windows files, and that didn't fix anything. From what I can tell, there could be a problem with my msgina.dll file, but everytime I try to fix my windows files everything seems ok.
I haven't installed any new software that could have screwed things up... well maybe I did reinstall my Creative sound drivers, but that was only because they were broken. I cleared out a bunch of junk from my Temp folder in Windows\, but I don't think that would have anything to do w/ it... That's really the only things I can think of that has changed.
