We've got an issue with our SCCM 2012 config (running on Windows Server 2012) with inactive clients being removed from the database.
We have a number of staff laptops which do not come onto the site for over 6 months at a time. These connect to our Citrix XenDesktop platform for remote access.
As far as I can see, it looks like with the default client status settings, a client that has been offsite (and hence offline) for 30 days will be marked as inactive, then the 'Delete Aged Discovery Data' maintenance task removes inactive clients after a further 90 days, hence a client that has not been connected to the network for 120 days will be deleted from the SCCM database.
I should mention that we have the 'Delete Inactive Client Discovery Data' task disabled.
What setting would you recommend changing, i.e client status settings or maintenance task settings, in order to prevent our staff laptops from being removed from the SCCM database? Otherwise, is there a way of marking the devices to prevent removal, or perhaps a group setting which I could apply to them?
