Adding Global Groups to Local Groups

[PreviousPoster]

I'm new at this and I've been doing a lot of research but just can't quite get it...I'm on Win 2003 server and Win XP Pro SP2 workstations. I've been researching on how to create a GPO that will put groups/users into the local users group, give full rights to certain application directories on the local machine, not allow users to install, and disable the Windows Firewall. Then a 2nd GPO to put a certain group into the local administrators group. Unfortunately, I'm not having any luck making this work. I have the GPO for the Local users group linked to one of our smaller containers with a small amount of users to test on. When I run GP modeling on the OU it shows that the GPO was applied but then when I run GP results on a certain computer it says the GPO was inaccessible. I have the right groups added under security filtering to give them read and apply rights. I feel like I'm missing something or I'm just not configuring the GPO correctly. I've tried it with global domain groups as Group name, no members in the 'members' and Users in the 'member of'; I've tried naming the group name Users, adding individual users and groups into the 'members' and leaving 'members of' empty. I just can't seem to get it to work. Any help would be greatly appreciated. :? Can I even do this with Win 2003 Server or is the only way to do this is with scripting?

Thanks!

I'm having the same problem with GPResult stating some of the policies are Inaccessible and can't figure out why.

Thank you,
