The Select Client Context(s) page lets you narrow the search to only those contexts that contain
managed users and computers, which improves performance.
Any client installation that attempts to check in with the management server the does not reside
in a selected context results in longer search times.
13 Click Next to display the Select Context(s) for Synchronization page.
14 (Optional) Select the contexts to synchronize as part of the configuration process.
The synchronization is performed in the background so you can immediately begin using your
new configuration. If you have many users and computers to synchronize, this might take a few
hours.
If you do not specify contexts to synchronize, the users and computers in those contexts are
populated in the Management Console when they check in.
Synchronizing contexts pre-populates the Management Console with those users and
computers so that you can immediately perform actions such as creating security policies.
When the users or computers check in to the system, those policies are pushed down and
applied. By pre-populating the Management Console, you can immediately begin creating
policies that are specific to individual users or computers, rather than creating a policy that
applies to all users and computers in the context. If you do not synchronize the context, you
must wait until those users and computers check in to the system before creating unique
policies for different users or computers.
