Where does this GP fall on the client?

Hi,

Iam looking for some help on this
We have a GP that after a 15 minute span password protects the screensaver and the user has to log back in again. I need to take this off of 7 laptops that are not connected to the domain right now. The clients are all Win XP Pro SP2. The servers (DC) are all Windows 2003 servers. Any in sight would be great!
