SQL Server Notification Services is a platform for developing and deploying applications that generate and send notifications. The notifications can be sent to a wide variety of devices, such as e-mail addresses, cell phone numbers, or Microsoft Windows Messenger clients. Applications built on Notification Services can scale to support thousands to millions of users. Notification Services 2.0 SP1 is a stand-alone release of Notification Services.

Details about the changes in SP1 are in the Readme.txt file. If you have an existing installation of Notification Services 2.0, you install SP1 side-by-side and then upgrade existing instances. Instructions for upgrading instances are in the Readme.txt file. Detailed instructions are in the ""Upgrading Notification Services 2.0 Instances to Notification Services 2.0 SP1"" paper, available on the Notification Services Technical Resources Web page. Each installed instance of Notification Services requires a valid SQL Server 2000 Standard Edition license.

Notification Services software components can be deployed on a single system. Please review the End User License Agreement (EULA) to understand the product licensing guidelines.
