Windows 2000 Server and server applications such as Exchange Server work in conjunction with Microsoft's licensing features to help you enforce licensing requirements and ensure that your organization has purchased the appropriate number--and correct type--of licenses for clients and server applications.

To help you track and manage licensing, you have two tools at your disposal. One is the Licensing applet in Control Panel. You can use the Licensing applet for the following actions:

* Change the licensing mode for Windows 2000 Server from Per Server to Per Seat.

* Add or remove licenses for applications licensed in Per Server mode.

* Configure properties for replication of licensing data to a site license server.

The Licensing console in the Administrative Tools folder offers a broader range of management features to help you manage licensing across your network. You can use the Licensing console for the following actions:

* View Per Server and Per Seat licenses for the site or a group in the site.

* Add or remove licenses for server applications.

* Review usage statistics by user for specific applications and servers.

* Manage licensing for remote servers licensed in Per Server mode.

* Manage license replication.

Using these tools effectively requires a solid understanding of Microsoft's licensing models. To learn more about Microsoft licensing, check out Microsoft's Client Access License (CAL) Guide.
