Need some dope on how to apply group policy on Windows Client using UCS as DC (I have already added windows client under the UCS domain).
Is it possible to apply polices & push software or updates remotely?
You can just use the standard Group Policy management tools. Just download the RSAT tools for the latest client to version of Windows you are running. Then make Group Policies as desired. I suggest having a policy for each single task, at least until you are a sure they work properly. It will be easier to diagnose issues.
