Terminal services windows server 2003

Hi All, I have an issue dealing with Terminal services in Windows server , the scenario is 1. Please let me know how to go about it. Wednesday, June 6, AM. Hi Santhosh, There is no built-in feature in Server to allow some users on a server to be restricted to a single session while allowing other users to not be restricted to a single session. Monday, June 18, AM. I have already gone thru many sites and searched but did not get any definitive solution.

Click Disabled, and then click OK. Using Terminal Services Configuration 1. Open Terminal Services Configuration. The kernel element of the bit subsystem handles interrupting all graphical output to the system driver.

This means that the session becomes invisible until the user reconnects or on reaching the predefined time limit for automatic removal of the disconnected session from memory. The applications that were open when the session was disconnected continue to run without interruption. For instance, an FTP client can continue downloading a document from the Internet without a problem in a separate user session, even though the user is no longer connected interactively. When a user requests a new connection to the terminal server after disconnecting, a new session is generated.

The logon screen prompts the user for authentication if the user ID was not automatically transmitted. If the system detects a separate session for this user from the logon ID and password, the user is reconnected to that session. The required drivers are loaded and the graphical subsystem is invoked to display the current session contents. If configured to do so, disconnecting and reconnecting can also be used on the server side for unstable network connections.

If a client loses the connection to the server, the server detects the interrupted data flow and saves the session for a preset period. Even if a client is accidentally switched off, no data is lost to the user. When the client is switched on again and the user logs on to the terminal server, the user is reconnected to the previous session. Of course, a user can log off a terminal server session, that is, terminate the session.

All resources that the session was using are released on the server. If you select Connections in the left panel, the right panel displays the protocols installed.

To modify all settings in Terminal Services configuration, you must be logged on as a user with administrative rights. Right-click the mouse to open the Connections context menu. The following options are displayed:. Create New Connection A wizard helps you set up a new connection. You need to enter the type of connection for example, RDP 5.

To set up a new connection, at least one of the parameters for connection type and transmission type, or for the network adapter, must differ from those for an already existing connection. View Adjusts the MMC console to the user s preferences. Adds or removes columns , sets the view to display large icons, small icons, lists, or details. This will start the connection wizard for Terminal Services. By selecting a connection protocol in the right panel of Terminal Services configuration and opening its context menu, you can enter several global settings.

One of them is especially important: the deactivation option under the All Tasks menu item. This option prohibits any other user from logging on to the terminal server using the connection protocol you selected. It is often needed to begin maintenance work on the server. When you select Properties for the connection protocol, the right panel displays a dialog box with eight tabs.

These tabs allow you to configure the connection parameters. The first tab is labeled General. Use this tab to enter an optional comment to describe the connection, the degree of encryption, and the standard authentication method you selected.

The transport protocol to transmit data streams over RDP 5. The RDP 5. For the server, you can choose between four degrees of encryption for data transmission between server and client for RDP 5. Low All data sent from the client to the server is protected with bit encryption. Data sent from the server to the client is not encrypted. Client-compatible All data transferred both from client to server and server to client is protected using the maximum encryption supported by the client.

The client thus determines the degree of encryption. However, this could allow unencrypted data to pass through the network, depending on the client configuration. High All data sent from the client to the server and vice versa is protected by an encryption using the maximum encryption supported by the server. For a standard terminal server, this is bits. International clients that do not support this encryption cannot connect to the server.

In some countries, the law limits the level of encryption; for example, the level might be limited to 64 bit.

Therefore, the specific language versions of Windows Server Terminal Services do not support higher encryption in these countries. Clients that must request a higher encryption cannot connect to the language-specific terminal servers with lower degrees of encryption.

If you activate the Use standard Windows authentication option, you cannot use any third-party security components for user authentication. In many countries, encryption under the Windows NT 4.

If you use older-generation RDP clients, they might support only bit encryption keys. If the degree of encryption is set to client-compatible, Windows Server Terminal Services will automatically adjust the encryption downward.

In production environments, you use this tab only to adapt the level of encryption to the corresponding requirements.

Other options are usually not as important here. The Logon settings are configured under another tab. On the client, you enter the logon information including the password, if required into the fields under the corresponding radio buttons. The data is passed on to the server at logon. Be careful not to confuse this with the single sign-on solution in which the information the user enters at logon is automatically used to establish a session on the client.

Even though this option is convenient for logging on to a terminal server session, it does present security problems. Furthermore, not all clients support this option. Alternatively, you can input a user name , domain, and password for logging on to the terminal server. This enables an automatic logon, too, and is valid for all user sessions requesting a connection over this type of protocol.

In many environments, however, there might still be security concerns regarding user access. Nonetheless, this is a very powerful option that allows anonymous users to access a terminal server running noncritical applications, for example, information terminals in a department store. You can make both logon options more secure by requiring the user to enter the password manually.

To activate this option, select Always request password option. This prevents the stored password from being used, no matter where it resides client side or server side. Regardless of the logon option, users will be required to enter their password each time they log on to the terminal server, thus significantly increasing security. In production environments, always select this option button, unless the user is authenticated in a special secured environment that is safe for password transmission.

The configuration of sessions on this tab sets the timeout limits for Terminal Services and determines the reconnection settings. The timeout limits are set using three counters. You have the choice of three predefined settings:. End a disconnected session This counter sets the maximum time a disconnected user session remains in memory. When the interval specified is completed, the session is ended; that is, the session is physically removed from memory, the user s applications are terminated, and the user is logged off.

Terminal Services configuration allows you to set the value for the protocol in question only RDP in the default installation only if you select Override user settings.

In this case, the setting you define here overrides the corresponding setting in the terminal server-specific expansions for local users and groups or users and computers in the Active Directory directory service. In this way, the terminal server administrator can set a generally valid standard for the behavior of Terminal Services for separate sessions. Active session limit This counter sets the maximum duration of a user session. When the time is up, the session is either disconnected or ended, depending on the settings specified in the following paragraph.

To set the active session limit value, you also need to override the user settings. Idle session limit With this counter, you set the time that a user can remain inactive. If the client logs back in to the same Terminal Server, a new session may be established, and the original session may still remain active. When you try to connect to the server by using a VPN connection, you receive the following error message:.

Terminal Services clients may be repeatedly denied access to the Terminal Server. If you are using a Terminal Services client to log on to the Terminal Server, you may receive one of the following error messages:. Because of a security error, the client could not connect to the Terminal server.

After making sure that you are logged on to the network, try connecting to the server again. Remote desktop disconnected. Because of a security error, the client could not connect to the remote computer. Verify that you are logged onto the network and then try connecting again. This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.

Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.

To resolve this issue, back up and then remove the X Certificate registry keys, restart the computer, and then reactivate the Terminal Services Licensing server. To do this, follow these steps. Type exported-parameters in the File name box, then click Save.

If you have to restore this registry subkey in the future, double-click the Exported-parameters. Under the Parameters registry subkey, right-click each of the following values, click Delete , and then click Yes to confirm the deletion:.

These early terminal servers had two modes, Application and Remote Administration. The situation in Server is that Remote Administration mode becomes Remote Desktop and is installed automatically on each Server Application is mode is the what the dozens of clients need to run their Remote Desktop session.

Application mode is what you install through Add or Remove programs. With the arrival of Windows Server many of the previous Terminal Service niggles have been ironed out.

For instance, we now have true color, rather than being limited to resolution. Local resources like files and com ports have been added to local printers. So that you benefits from all the server resources as well as having the local resources available when wanted. Another improvement in Windows is a more efficient network connection, quite frankly, I have never found the network bandwidth to be a problem with Terminal Services, the bottleneck is more often memory on the server.

If I have one tiny criticism of Terminal Service it is that you need to check three different interfaces to configure the settings, Licensing, Configuration and Server Manager.
