I'm working on pushing out the SCCM clients to my users, and the installs are going great!

The only problem I'm having (so far) is, that my collections are not updating.
The first group of users that I allowed the client to be installed on started to show up on collections after about a week.
(We are a secondary site.)
(I'm using the "auto enroll" method / native mode.)
Should the client "check in" after install, and show up in a refreshed collection?

:
Is there a "task" that polls for the clients?

:
Is there a schedule for soem sort of sccm secondary to primary "replication"?

: (Assuming the clients are checking in with our sccm server?!)
Thank you!
