Endpoint Protection Small Business Edition upgrade from 12.1.1101.401 to 12.1.4013.4013 change policy

Hi,

A few days ago I upgraded Symantec Endpoint Protection Small Business Edition from 12.1.1101.401 to 12.1.4013.4013 without any problem. The next day, when the clients updated and were rebooted, I got a message that Network Intrusion Prevention and Browser Intrusion Prevention where disabled by policy. Is this normal? How can I change it? Can I go back to the previous policy?

Policy serial number before upgrade: B265-01/28/2013 23:00:11 318

Policy serial number after upgrade: B265-02/12/2014 21:18:56 282

Thanks in advance.

Kind regards

Sven
