Hello Annie,

Duplicate SEP clients appear in the Symantec Endpoint Protection Manager console

There are two causes for this issue:

Current Theory: The first possible cause for this is when an Endpoint has been re-imaged (whether in a virtual machine or on a physical system).

Things we know: Each installation of Symantec Endpoint Protection (SEP) randomly creates a "Unique Identifier" for the client. So if this changes and the re-imaged system checks in, it is recognized as a new client.

Example: The IP and computer name are the same, yet the database still shows a different Unique ID.

The second cause for this is related to an issue with moving clients to a different OU in Active Directory.

Duplicate Endpoint Protection client IDs occur if the base image was not prepared for cloning. For more information, read the article How to prepare a Symantec Endpoint Protection 12.1 client for cloning.

However to Resolve this issue, check these Articles for SEP 12.1: -

To prevent this from happening, I would recommend you to prepare your clients before cloning /image, check this article:

This issue is occur if you have installed client with image disk or if the client come in network after long time.

For that you can set the day to remove the old system entry.

It will reduce the duplicacy.
