You can update the policies on the Symantec Endpoint Protection client computer if you do not think you have the latest. If the client does not receive the update, there might be a communication problem.
Check the policy serial number to check whether your managed client computers can communicate with the management server.
You can only manually update the policy on the client computer. If policy settings prevent you from opening the user interface or the notification area icon, you may not be able to manually update the policy.
No command exists in Symantec Endpoint Protection Manager to manually prompt the client to update policies. The client checks in for policy updates based on its update method of pull mode or push mode.
