Technical Solution


Upgrading a Symantec Endpoint Protection (SEP) 11 client to SEP 12.1 results in duplicate client entries in the Symantec Endpoint Protection Management (SEPM) console. Typically this is observed if the client is on a Guest OS of Hyper-V, but in some circumstances it can happen on any client.

A similar result may happen when a SEP 12.1 client is installed fresh on a clean OS (Guest of Hyper-V) and then the "Repair Install" is executed via Add/Remove Programs.  After the repair is complete, additional client entries may be created on the SEPM console.


Workaround:  Manually remove old duplicate client entries in the SEPM.

This issue is resolved in Symantec Endpoint Protection 12.1 RU1 MP1.

The SEP client installer was modified to prevent a condition where the hardware ID is re-generated, resulting in a duplicate client entry.
