Enabling Group Policies

I have some win2k machines, currently without a domain. I need to enable some group policies so they can’t mess with the system settings, display etc. I have used the gpedit.msc as my template and made my changes. Also created a group with my specific users (no admin) in it. Problem is the changes I’ve made in gpedit.msc affect the admin account as well, even though it is not in my group. Does anyone have any suggestions, or suggestion on good reading material for this feat. I have tried the Win2k Pro Resource Kit, but is very broad. Thanks.
