Cloud-enabled Management mode is disabled in Altiris 7.5 Agent

Hello Team,

I have pushed the Altiris Agent on few computers from the Notification Server and found it to be successfully installed. They were all connected to the corporate LAN network. But when I remove them from the Corporate Network and connects to Internet, Cloud Mode is not getting enabled. CEM Policy has been applied to all these computers.

When I use the CEM Package - It works fine. Cloud Mode is Enabled and when I connect to LAN, It is pointing to LAN Site Server. This works absolutely fine.

Basically, what I want is :- I want to push the altiris agents from the NS console and when user connects to Internet, Agent has to get changed automatically to Cloud Mode.
