We are using SCCM 2012 R2 SP1 to deploy software updates campus wide. We also do have bunch of domain-joined laptops that users take home at end of the day. We are making sure that all laptops should have SCCM client. Now, all other desktops can be restarted in the maintenance windows but laptops are becoming our nightmare. We can't restart them during day and once they leave the campus, they won't connect to our VPN so that SCCM client can work. We are not planning for Intunes as well.
Now, what's the best strategy to resolve this issue. What I want, if laptops can download the updates during the time when they are on campus and get the notification that updates are ready to install, it would be awesome. Is it possible in our current SCCM 2012 setup?
