1. Go to <Install Drive>\Program Files\Altiris\Notification Server\Bin\Tools\ 

2. Open NSConfigurator 

3. Expand Security Settings -> DbEncryptedConnection 

4. Check the box "Enabled" 

5. Click "Save"

5. Restart all the altiris services and SQL services (on the SQL box) : 

- Altiris Client Msg Dispatcher 

- Altiris Client Task Data Loader 

- Altiris Event Engine 

- Altiris Event Receiver 

- Altiris File Receiver 

- Altiris Inventory Rule Management Service 

- Altiris Monitor Agent 

- Altiris Object Host Service

Now the Symantec Management Platform should communicate with SQL using encryption
