|Overview of Licensing and and Product Activation|
For most products, you will need one Bamboo product License Key per Web Front End (WFE) server. A WFE server is any farm server running the Microsoft SharePoint Foundation Web Application (or Windows SharePoint Services Web Application in WSSv3/MOSS).
To determine which servers on the farm run these services, go to Central Administration > System Settings > and then Manage servers in this farm. If you are using WSSv3/MOSS, this page is accessed in Central Administration through Operations > Servers in Farm. In this example, there are two WFE servers on the farm.
Some SharePoint farms have WFE servers that do not serve content to users, even though they are running the Microsoft SharePoint Foundation Web Application. You will not need a license key for WFEs that do not deliver content to end users.
Desktop applications, such as List Bulk Import and List Bulk Export require only one license per instance.
Some products, such as List Rollup and Alert Plus may include optional components that run on application servers in addition to WFE servers. To use these product features, you may need an additional server license for each separate (non-WFE) application server on which you would like to run the associated service for that product. Using application server features on already licensed WFE servers does not require any additional licensing.
