Different types of computers in your organization require different approaches to software updating. Employee workstations run software that application servers do not. Some servers are mission critical and must only be updated after you test the updates thoroughly. Sometimes critical updates are released that must be applied immediately, while some may be optional.
To manage the distribution software updates, define computer target groups on your WSUS server and assign computers these target groups. Each computer target group can be configured to apply updates differently. You create a target group for the Domain Controllers in this recipe.
