client with Firewall status disabled after upgrade to RU3

Hi,

I upgraded my SEPM to 12.1 RU3 and did an upgrade test to one of the clients (this client is in fact on the SEPM server)

Everything went fine and both server and client are up to date...except the client has a "firewall status" disabled now and when I look at the NTP settings, I can see the firewall isn't enable although I didn't change anything to the firewall policy and all the other clients still in RU2 are ok.

Any idea ?

Thanks !

Eric
