The COM+ System Application (COMSysApp) service manages the configuration and tracking of COM+ based components. If this service stops, most COM+ based components do not function properly. The Volume Shadow Copy Service, which is needed for Windows Backup and backup applications that rely on the Windows Backup API, requires this service.
This service is installed by default and its startup type is Manual. When started in n its default configuration it logs on by using the Local System account.
The COM+ System Application service is dependent upon the following system components:
- COM+ Event System
- Remote Procedure Call (RPC)
- DCOM Server Process Launcher
- RPC Endpoint Mapper
- System Event Notification Service
