Difference between Obsolete and Inactive Clients

Obsolete Clients

Obsolete client s are those that have been replaced by new ones. This usually happens during refresh OS deployments where the hardware stays the same and thus the hardware id is the same but the SMS GUID changes because the OS has been reloaded or the GUID is regenerated for another reason but the hardware remains the same.

Reasons -
1. hard disk swapping
2. Renaming machines
3. Reimage OS
4. Reinstalling SMS/SCCM agent on the machines without proper uninstall.

Inactive Clients 

Inactive client s are those that have not been discovered recently by the heartbeat discovery. The definition of recently is defined in the delete task as a number of days. Please note that obsolete client s are also marked inactive.

Reasons-
1. Offline machines
2. Machines having DNS issue/No name resolution
3. Machines are in inventory stock
