This article contains information that can help you understand and successfully deploy Terminal Services on computers that are running Microsoft Windows Server 2003. This article discusses the following topics:
Licensing requirements for computers that access a Windows Server 2003-based Terminal ServerThe Windows Server 2003 licensing model requires a server license for each copy of the server software that is installed. Terminal Services functionality is included in this Windows Server 2003 license. In addition to a server license, a Windows Server 2003 CAL (Windows CAL) is required. If you want to conduct a Windows session, an incremental Terminal Server Client Access License (TS CAL) is required also. A Windows session is defined as a session where the server software hosts a graphical user interface (GUI) on a device. For Windows sessions, a TS CAL is required for each user or device. The following two types of TS CALs are available:
Note To use both User and Device TS CALs at the same time on the same Terminal Server, configure the server to use the Per User TS CAL licensing option. Failure to have the appropriate number of User CALs or Device CALs for each device or user who is connecting is a violation of the EULA.
With Microsoft Windows 2000 Terminal Services licensing, if a client device is running the most recent version of the Windows desktop operating system, it does not have to have a TS CAL to satisfy the licensing requirement. However, with Windows Server 2003, a TS CAL is required for each device that or user who is using Terminal Services functionality, regardless of the operating system that is running on that device.
Transitional CALs for Windows XP Professional-based client computersBecause this change in client access licensing requirements affects you as you move to Windows Server 2003-based terminal servers, Microsoft offered a Windows Server 2003 TS CAL for each Windows XP Professional license that you owned before April 24, 2003. This offer and the related campaign were ended on June 30, 2007.
For more information about these transitional licenses, visit the following Microsoft Web site:
Terminal Server Microsoft Client Access License Agreement and Cover LetterYou can use one of the following methods to obtain transitional CAL licenses, depending on how you obtained the Windows XP Professional operating system licenses.
Method 1: For Windows XP Professional licenses that were obtained through the volume licensing programUse the Install Licenses command on the Action menu in the Terminal Server Licensing utility. You must provide your volume licensing program information (Enrollment number, Agreement number, or License and Authorization numbers, depending on the program type) together with the requested number and type of terminal server CAL tokens. The information that you enter in the Terminal Server Licensing utility is validated by Microsoft Clearinghouse, and when your request for tokens is within the boundaries of the entitlement program, license tokens are installed in the Terminal Server License Server.
Method 2: For Windows XP Professional licenses that were obtained through retail or OEM channelsIf you obtained your Windows XP Professional licenses through a retail or an OEM channel, these licenses will have a product key included. You can find the product key on the retail packaging or on the Certificate Of Authenticity (COA) sticker on the computer case. To obtain a transitional CAL license, follow these steps:
How to deploy Windows Server 2003 Terminal ServicesA Windows Server 2003-based terminal server communicates only with a Windows Server 2003-based Terminal Server License Server. You cannot install Windows Server 2003 TS CALs on a Windows 2000-based Terminal Server License Server. When you upgrade Windows 2000-based terminal servers to Windows Server 2003, you must install and activate Windows Server 2003 Terminal Server License Server or upgrade an existing Windows 2000 License Server to Windows Server 2003. Windows Server 2003 Terminal Server License Servers can communicate with both Windows 2000-based and Windows Server 2003-based terminal servers. When you deploy Windows Server 2003 Terminal Services in a Windows 2000 domain, you have the following licensing options:
If the Windows Server 2003-based Terminal Server License Server is a domain license server, you must modify the registry on each of your Windows Server 2003-based terminal servers so that they can discover a compatible license server. You must configure the registry settings on Windows 2000-based and Windows Server 2003-based terminal servers that are running in application mode so that they can discover the license server that issues the Windows 2000 or Windows Server 2003 TS CALs.

Management limitations for user CALsA Windows Server 2003-based Terminal Server Licensing Server that is running in TS User CAL licensing mode does not decrement the number of available Windows Server 2003 TS CALs when each user connects to the terminal server. This limitation does not remove the responsibility from administrators to make sure that a valid TS CAL is obtained for each connected user, per the End User License Agreement (EULA).

How to determine whether to contact Microsoft Clearinghouse or Microsoft PSSContact Microsoft Clearinghouse to activate a Terminal Server License Server or to install TS CALs. To contact Microsoft Clearinghouse by telephone, use the following number:
(888) 571-2048If you purchased TS CALs through the Select, Enterprise Agreement, Campus, School, or Open licensing method, you can use the Automatic connection (recommended) option or the Web Browser connection option to activate and install TS CAL tokens. To use the automatic connection method to install TS CALs, follow these steps:
Contact Microsoft PSS if you experience issues that are related to either of the following:
Note Microsoft PSS and Microsoft Clearinghouse cannot help you to locate your licensing purchase agreement or authorization number(s) to install license key packages. To obtain this information, contact the reseller where you obtained your Microsoft product.
