10. Managing CALs When in Steady Operations
When Windows Server 2003 Terminal Server is working properly, you can ensure that all the correct types of Terminal Server CALs are available to users and computers in your environment. To do this, refer to the following important facts about Terminal Server CAL management in Windows Server 2003 Terminal Server:
• You can use Terminal Server Licensing to monitor licenses. To get this tool, click Start, Programs, Administrative Tools, and then Terminal Server Licensing on the computer running Terminal Server Licensing.
• Managing Per User Licensing is currently not supported. This means that when you install per User CALs on your license server, you cannot monitor how many per User CALs are available at any time.
• Temporary licenses are issued on first connection to a terminal server in Per Device mode. The first time a device connects to a terminal server, it is issued a temporary license, which is valid for 90 days. This behavior is by design so that devices do not accidentally use up a CAL when mistakenly connecting to a terminal server. The next time the client connects to a terminal server, it is allocated a permanent Terminal Server CAL token, which the device stores for later connections. This behavior is valid only for terminal servers in Per Device mode.
• It is not possible to recall issued permanent licenses immediately. Terminal Server issues permanent licenses to various devices, which are valid for from 52 to 89 days. It is currently not possible for a client to give up an issued license immediately and explicitly. The only way to recover a license from a client is to ensure that the client does not connect to the Terminal Server within the next 89 days. After that period, the license issued to the client expires, the license is reclaimed by the License Server, and it becomes available for distribution to another client.
• You must call Microsoft Clearinghouse to move licenses from one computer to another and to get the keypacks that go with the new server ID. Each activated license server is unique and is identified with a certificate provided during activation. Simply moving the licensing database from one computer to another does not complete the process. You actually need to reinstall licenses on the new computer as a part of moving the licenses. For the correct local phone number to call the Microsoft Clearinghouse, use Terminal Server Licensing.
• You must call Microsoft Clearinghouse to install and move the existing Windows 2000 Licenses to a Windows Server 2003 license server. A license server that runs on Windows Server 2003 supports both Windows Server 2003 and Windows 2000 Terminal Server licenses. However, if you upgrade or migrate your Windows 2000 license server, you need to reinstall the Windows 2000 Terminal Server CALs on the Windows Server 2003 license server. For reinstallation, you need to call the Microsoft Clearinghouse to get the license keypacks that go with the new server ID.
• You can configure your terminal servers so that you have greater control over how the license server issues licenses. You can then control which terminal servers take licenses from a specific license server.
