Notification Services is available with the following editions of SQL Server 2005: Developer Edition, Standard Edition, Enterprise Edition, and Evaluation Edition. For Notification Services, Developer Edition, Enterprise Edition, and Evaluation Edition all have the same functionality. However, the Standard Edition of Notification Services has some limitations.
