Group Policy... a noob reference?
As background: I have completed an MCSA course, but it was 6 years ago, and my server skills are rusty.
I'm trying to administrate a two domain network at a school, which is locked down quite heavily on the student side via group policy (but also using some bespoke software).
Because the system was already setup when I arrived I'm struggling a bit to get to grips with what was done to Group Policy, and just Group Policy in general.
Can anyone recommend a good reference for understanding group policy, or some alternative for trying to understand it better?
