Configuring a COM+ Server Application as a Service Application

  • Article

A COM+ server application can be created as a service to start either automatically during the system startup or manually by activations. If the service fails to start, the option for error handling specifies the severity of the error and determines the action to be taken. The option to configure a service to run as the local system account is also available, as well as the option to assign a specific user account for which the COM+ server application will run. Dependencies can also be selected from a list of services registered on the computer using Component Services. This will determine which services must be executed before this service is started.

To configure a COM+ application to run as a service

  1. In the console tree of the Component Services administrative tool, locate the COM+ server application you want to run as a service.

  2. Right-click the COM+ server application, and then click Properties.

  3. In the Properties dialog box, click the Activation tab.

  4. In the Activation type box, check the Run application as NT Service check box.

    Note

    The Run application as NT Service check box is enabled only for server applications and is disabled for library applications.

     

  5. Click the Setup New Service button.

  6. In the Startup type box in the Service Name dialog box, select Automatic or Manual.

  7. (Optional) To specify the action to be taken for a particular error, select Ignore, Normal, Severe, or Critical in the Error Handling box. The behavior associated with each option is as follows:

    1. Ignore. The startup program logs the error but continues the startup operation.
    2. Normal. The error is logged, a message box is displayed, and the startup program continues the startup operation.
    3. Severe. The error is logged, and the system is restarted with the last known good configuration. If it is the last known good configuration that is being started when the error is logged, the startup operation continues.
    4. Critical. The error is logged, and the system is restarted with the last known good configuration. If it is the last known good configuration that is being started when the error is logged, the startup operation fails.

  8. (Optional) To set other services as dependent, select the dependent services from the list in the Dependencies box.

  9. (Optional) To indicate that the service should be allowed to interact with the desktop, check the Allow service to interact with desktop check box.

  10. Click Create.

  11. (Optional) To assign the service to a user account:

    1. In the Identity tab, select This user.
    2. To select the user, enter the user name in the User box or click the Browse button.
    3. Enter the password for the user account in the Password box.
    4. Enter the same password in the Confirm Password box.
