Overview
This post will contain a listing of Group Policies, in no particular order, that I like to set up. For reference, I generally follow C_ for computer objects and U_ for user objects. If there is a policy that applies to both, I will use CU_.
I like to get these built before I add computer objects to the domain, but sometimes that does not happen. If you add a computer object before a policy is created, you can wait for the policy to apply by default, reboot the computer or server two times (one to obtain the policy and the other to apply), or force an update by using gpupdate on the new computer or server.
