Local PC Group Policy copied to Remote PC

I have a very strange thing happening when using Remote Desktop. I remote to
my home machine from work, and when I disconnect the session and go home...
settings from my work PC are in effect on my home PC. For example... I use
the default "Window's XP" screensaver at work, and a completely different
screensaver at home. When I get home after using RD, my screensaver will be
the default Window's screensaver, just like my work machine. Also, my power
settings change, b/c my monitor at work is set to never go into powersave
mode, but my home machine is. After a RD session, my home machine's monitor
will not go into powersave like it should, b/c it's brought over settings
from my work machine.

And, we've been seeing this with several of our users who work from home,
and have their home Screensaver settings copied to their work machines after
using Remote Desktop.

I've done some extensive searching on this, and can't seem to find anything.
Any ideas at all on this bizarre behavior? Thanks
