I have never had to attach a GPO to an OU container, I normal have just had to create policy and link it to the domain root.
I have an OU, inside my OU in AD users and computers I have a Group, and memebrs to that group are users.
I cleared all default and other GPO that have been created on a test server(clean install),
I created a GPO policy and attached it to the OU in Group Policy Management Console.
When i log onto XP machine which has been registered to the above server, nothing is applied.
If I go and cancel linking on OU, and attach it to the Domain Root, all works?
My GPO, only has filtering set to the Group Container that is within the OU in question, it does have read and apply GPO permission.
Can anyone help ?
