By default Intellect uses internal synchronization, i.e. there is data interchange between computers in the distributed configuration (see Configuring the interaction of distributed system components):

1. If a computer is in the distributed system, then all the events are sent just as they appear. This is online synchronization.
2. If a computer lost connection with the distributed system and cannot interchange the events with other computers, then events that are to be sent to this computer are stored in the database and sent on it after the computer is reconnected. This is offline synchronization.

If the computer has not been in the distributed system for too long, then the accumulated sequence of events can be quite long and processing of all these events can take much time. Thus offline synchronization can be disabled.

In this case, configure DB synchronization — see Database synchronization setup and Configuring the Event Viewer databases synchronization.

Configure internal synchronization as follows:

1. Go to the Programming tab of the System settings dialog box (1).
   
2. Select the Security zone object in the tree (2). The settings panel of this object is displayed on the right side of the System settings dialog box.
3. To disable offline synchronization, set the Offline synchronization checkbox unchecked (3).
4. Click the Apply button (4).

Internal synchronization is now configured.
