Planning the Terminal Services Configuration 561 installed on domain controllers. In workgroups or Windows NT 4 domains, domain license servers can be installed on any member server. In order to deploy Terminal Services, you will be required to obtain server and client licenses. The licenses you may need are described in Table 12.2. TABLE 12.2 Terminal Services Licenses License Description Windows 2000 Server license This server license is included when you purchase Windows 2000 Server. Windows 2000 Server Client Access license This license is required for all com- puters or Terminal Services clients that connect to a Windows 2000 server. This license is required by all connecting computers to use file, print, and other network ser- vices, regardless of whether they are using Terminal Services. Windows 2000 Terminal Services Client Access license or Windows 2000 Professional license Every Terminal Services client needs to have a Windows 2000 Terminal Services Client Access license in addition to a Windows 2000 Server Client Access license. This license provides each Terminal Services cli- ent the right to connect to a Terminal Services server and run applications on the server. Windows 2000 Profes- sional machines that are used as Ter- minal Services clients are automatically licensed to connect to Terminal Services. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com 562 Chapter 12  Administering Terminal Services Installing and Configuring the Terminal Services Server T he Terminal server controls all of the Terminal clients that are connected to it. All Terminal Services operations actually take place on the Terminal server. Windows 2000 Terminal Services Internet Connector license This license can be purchased and used separately from the client access licenses described above. This license allows up to 200 clients to connect anonymously from the Internet. This is useful for providing Windows-based applications to the public without porting them to a Web-based format. Users who access Terminal Services with this license must be nonemployees. Work at Home Windows 2000 Terminal Services Client Access license This license is required for users who want to use Terminal Services to access the Windows 2000 Desktop and applications from home. You can purchase a Work at Home Windows 2000 Terminal Services Client Access license for each Terminal Services Cli- ent Access license owned. The Work at Home license includes a Windows 2000 Server Client Access license, but does not include application licenses, which must be purchased separately. TABLE 12.2 Terminal Services Licenses (continued) License Description Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Installing and Configuring the Terminal Services Server 563 The clients are nothing more than dummy windows that display information sent from the server and send mouse and keyboard information to the server. After you install Terminal Services, you can configure many settings that con- trol how users and sessions are handled by the Terminal server through the Ter- minal Server Configuration utility. You can use the Terminal Services Manager utility to view every server and session on the network and manually perform actions such as immediately disconnecting from or sending messages to sessions. Installing the Terminal Services Server You install Terminal Services through the Add/Remove Programs icon in Control Panel. Terminal Services can only be configured to support one mode at a time, either remote administration mode or application server mode. In the following sections, you will learn how to install both Terminal Services modes. Installing Terminal Services in Remote Administration Mode You should install Terminal Services in remote administration mode if you want to be able to perform administrative tasks from any client on the network, rather than needing to work from the server console. To install Terminal Services in remote administration mode, take the following steps: 1. Select Start  Settings  Control Panel. Double-click the Add/Remove Programs icon. 2. The Add/Remove Programs window appears. Click the Add/Remove Windows Components option. 3. The Windows Components Wizard starts.

In the next Terminal Services Setup dialog box, select the Per- missions Compatible with Windows 2000 Users radio button and click the Next button. 6. If you are notified that certain applications may not work properly after installing Terminal Services in application server mode, click the Next button. (You should reinstall these applications after you’ve installed Terminal Services.) 7. The appropriate files will be copied from the Windows 2000 Server CD. Reboot when prompted by clicking the Yes button. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Installing and Configuring the Terminal Services Server 567 Configuring the Terminal Services Server With the Terminal Services Configuration utility, you can change the properties of the RDP-TCP (Remote Desktop Protocol-Transmission Control Protocol) connection that is created when you install Terminal Services. You can also add new connections with this utility. To open Terminal Services Configuration, select Start  Programs  Adminis- trative Tools  Terminal Services Configuration. The main Terminal Services Configuration window is shown in Figure 12.3. FIGURE 12.3 The Terminal Services Configuration window Managing Connections To configure the properties for a specific connection, select the Connections folder, right-click the connection in the Terminal Services Configuration window, and select Properties from the pop-up menu. This brings up the RDP-Tcp Properties dialog box, as shown in Figure 12.4. This dialog box has eight tabs: General, Logon Settings, Sessions, Environment, Remote Control, Client Settings, Network Adapter, and Permissions. The options on these tabs are described in the following sections. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com 568 Chapter 12  Administering Terminal Services FIGURE 12.4 The General tab of the RDP-Tcp Properties dialog box Configuring General Properties The General tab (see Figure 12.4) shows the connection type and transport protocol. In this tab, you can specify a comment for the connection, select the encryption level that will be used, and choose whether or not standard Windows authentication will be used. You will see an option for another authentication method if another authentication package has been installed on the server. Terminal Services uses the standard RSA RC4 encryption method when transferring data between the server and clients. You can change the level of encryption depending on your needs. The Encryption Level drop-down list has three choices:  The Low setting secures all data sent from the client to the server, but not from the server to the client. Windows 2000-based clients use a 56-bit key. Earlier versions of the client use a 40-bit key.  The Medium setting secures data traveling in both directions. This encryption level uses the same keys as the Low setting.  The High setting secures data traveling in both directions. This encryption level uses a 128-bit key. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Installing and Configuring the Terminal Services Server 569 Configuring Logon Settings The Logon Settings tab, shown in Figure 12.5, allows you to specify whether the client will provide logon information or whether the logon information will be preconfigured. You can also specify whether the user will always be prompted for a password. FIGURE 12.5 The Logon Settings tab of the RDP-Tcp Properties dialog box Configuring Sessions Settings The Sessions tab, shown in Figure 12.6, allows you to configure session timeout and reconnection settings. You can limit the amount of time that active, idle, and disconnected sessions remain running on the server. You also can set whether the session should end or be disconnected when the time limit is reached. A disconnected session is saved on the server, and the disconnected user can reconnect from any client without losing any data. Ending a session closes all of the user’s applications immediately, usually resulting in lost data.
