Over time, obsolete clients can accumulate in the Symantec Endpoint Protection Manager database. Obsolete clients are those clients that have not connected to Symantec Endpoint Protection Manager for 30 days. Symantec Endpoint Protection Manager purges obsolete clients every 30 days by default.
If you do not want to wait the same number of days to purge obsolete non-persistent clients, you can configure a separate interval for them. If you do not configure a separate interval, then offline non-persistent virtual clients are purged at the same interval that obsolete physical clients are purged.
Online non-persistent clients count toward the number of deployed licenses; offline non-persistent clients do not.
You can also filter the offline non-persistent clients out of the view on the Clients page.
