A method and system for providing system event notifications to clients such as applications. Clients register for notification of one or more types of events with a registration mechanism, and a System Event Notification Service, (SENS), receives system event information and fires event notifications in response thereto. A distribution mechanism selectively communicates the fired event to each client registered for notification thereof based on the type of event. Events include network events, for which the service monitors the connectivity state of the machine, including whether a connection is established or lost, the type of connection (LAN/WAN) and bandwidth information. To monitor a LAN state, the service caches outgoing and incoming network information including errors and packet counts and statistically evaluates this cached information against current information to determine whether the connection is established or lost. The service also determines if a destination (IP address or name) is reachable, by periodically polling destinations. Other system event notifications may be fired, including logon or logoff operations and power management events.

A centralized manager for managing the data synchronization operations for multiple applications according to user preferences. Applications register respective COM handlers with the synchronization manager via COM methods. On a synchronize event the synchronization manager queues the registered application handlers, and calls the handlers to perform the synchronization of items therein. Progress and results are communicated to a user-viewable dialog via callbacks from the handlers to the synchronization manager. The synchronization manager provides consistent user interfaces for obtaining user preferences related to synchronization and for presenting information to the user, thus resulting in a consistent user experience.
