Description: The System Event Notification service (SENS) tracks system events such as Windows logon network and power events, and notifies the COM+ Event System service subscribers of these events.
If this service is stopped or disabled, COM+ Event System service subscribers do not receive system event notifications. They also encounter the following problems:
Win32 APIs IsNetworkAlive() and IsDestinationReachable() APIs do not work. These APIs are mostly used by mobile applications on portable computers.
ISens* interfaces — specifically, SENS Logon/Logoff notifications — do not work.
SyncMgr (mobsync.exe) does not work properly, because it depends on connectivity information and also on Network Connect/Disconnect and Logon/Logoff notifications from SENS.
COM+ EventSystem tries to notify SENS of some events, but it does not succeed.
