Generating a new Hardware Key may be required in a specific situations related to client registration process.

Cause

Hardware Key is a value used to identify a SEP client during registration with SEPM. It is calculated based on different "IDs" (such as computer name, OS version, MAC addresses, etc.). Such value is stored in the DB, and can affect re-registration process of the client or be a part of multiple cloned client entries issue. 

Resolution

  1. Locate and delete Hardware ID from the registry (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Symantec\Symantec Endpoint Protection\SMC\SYLINK\SyLink).
  2. Locate and delete sephwid (C:\ProgramData\Symantec\Symantec Endpoint Protection\PersistedData).
  3. Restart client.

This forces client to generate a new hardware key which is unique every time.
