Group Policy

Running windows 2003 standard edition, no management console installed.

These are the group policies that i can not figure out / locate them.

-the computer must lock (not log off) if idle for more than 2 minutes

-users are allowed to change the network address of the computer

-The user’s wallpaper is to have an image with the acceptable usage policy on it. This is not to be changed or deleted.

Any guide or help will be appreitated appreciated
