Symantec Endpoint Protection Manager can incorrectly display an over-deployed license status due to obsolete clients. These are database entries for the clients that no longer communicate with Symantec Endpoint Protection Manager in the protected environment. Clients can be rendered obsolete for many reasons, such as when you upgrade the operating system, decommission a computer, or change the hardware configuration.
If your license reports show more seats are licensed than known to be deployed, you should purge the database of obsolete clients. Obsolete clients count against the product license, so it is important to purge obsolete clients as soon as they are created. By default, purging occurs every 30 days. You can shorten the interval between purge cycles to more quickly purge the obsolete clients. You reset the interval as needed to suit your long-term needs after the purge cycle completes.
In non-persistent Virtual Desktop Infrastructures (VDIs), you can set a separate time period for purging the non-persistent clients. This setting purges the offline clients that have not connected during the time period that you set. Non-persistent offline clients do not affect the license count.
To purge obsolete clients from the database to make more licenses available
In the console, on the Admin page, click Domains, right-click the domain, and click Edit Domain Properties.
On the General tab, change the Delete clients that have not connected for specified time setting from the default of 30 to 1.
You do not need to set the option to purge the non-persistent clients for licensing purposes. The non-persistent clients that are offline do not count toward the license total.
Wait 24 hours and then revert the settings to 30 days or to another interval that suits your requirements.
