It is mentioned that WSUS can be managed by group policy. In the demo of Implement WSUS part 2 Cherokee creates a new AD group and populates it with a server. It isn't necessary to create new groups for applying wsus group policy is it? WSUS can be applied to an existing AD structure can't it? I'm imagining the amount of work and re-structuring if WSUS is applied to an existing AD structure if new groups are needed.
