    Hello,

    One of my biggest struggles with moving to SCCM 2012 from a product like Altiris was the understanding of the client installation and the life-cycle of a client.  I'm used to a client being installed on a machine and then it remains in the console as installed until the client was removed or the object was removed from the console.  It seems like each week I have a different client count in the console.  I was told by an engineer to disable the Heartbeat Discovery in order to prevent clients from being removed by the Maintenance Tasks on the weekend so I did that and after the maintenance task that weekend I have 700 machines that had the client showing before now without the client.  I re-anabled Heartbeat Discovery and some of them came back with an activated client but I still don't feel like I have a predictable situation here.  I don't want to worry during the start of each week that there are machines now showing with no client or any other weird stuff showing up.  

    Does anybody have a good explanation of these processes?  Or know of a good article that goes through all of this in depth?

    If you want to know more about heartbeat discovery, see http://blog.configmgrftw.com/?p=139 . This blog is for CofigMgr 2007 but I don't think there is much change in the CM12 process as well.

    Disabling heartbeat does not prevent clients from being removed from the database. It's the opposite! Leave heartbeat enabled.
    It's all a matter of the configuration of the "delete ..." maintenance tasks and discovery methods.

    Thanks, Torsten.  That's what I thought.

    As for those 'delete' maintenance tasks, is it recommended to disable those entirely?  During our Summer months we may have machines that are not turned on for 60-90 days so I don't want them getting purged at some point.  I basically don't want a client to go away unless I physically uninstall the client or delete the object from AD.

    No need to turn things off, adjust them to tolerate the conditions required (90+ days for deletions for example)
