Turn Off UDP On Client

This policy setting specifies whether the UDP protocol will be used to access servers via Remote Desktop Protocol. If you enable this policy setting Remote Desktop Protocol traffic will only use the TCP protocol. If you disable or do not configure this policy setting Remote Desktop Protocol traffic will attempt to use both TCP and UDP protocols.

Configure compression for RemoteFX data

This policy setting allows you to specify which Remote Desktop Protocol (RDP) compression algorithm to use. By default servers use an RDP compression algorithm that is based on the server’s hardware configuration. If you enable this policy setting you can specify which RDP compression algorithm to use. If you select the algorithm that is optimized to use less memory this option is less memory-intensive but uses more network bandwidth. If you select the algorithm that is optimized to use less network bandwidth this option uses less network bandwidth but is more memory-intensive. Additionally a third option is available that balances memory usage and network bandwidth. In Windows 8 only the compression algorithm that balances memory usage and bandwidth is used. You can also choose not to use an RDP compression algorithm. Choosing not to use an RDP compression algorithm will use more network bandwidth and is only recommended if you are using a hardware device that is designed to optimize network traffic. Even if you choose not to use an RDP compression algorithm some graphics data will still be compressed. If you disable or do not configure this policy setting the default RDP compression algorithm will be used.

Use advanced RemoteFX graphics for RemoteApp

This policy setting allows you to enable RemoteApp programs to use advanced graphics including support for transparency live thumbnails and seamless application moves. This policy setting applies only to RemoteApp programs and does not apply to remote desktop sessions. If you enable or do not configure this policy setting RemoteApp programs published from this RD Session Host server will use these advanced graphics. If you disable this policy setting RemoteApp programs published from this RD Session Host server will not use these advanced graphics. You may want to choose this option if you discover that applications published as RemoteApp programs do not support these advanced graphics.

Optimize visual experience for Remote Desktop Service Sessions

This policy setting allows you to specify the visual experience that remote users receive in Remote Desktop Services sessions. Remote sessions on the remote computer are then optimized to support this visual experience. By default Remote Desktop Services sessions are optimized for rich multimedia such as applications that use Silverlight or Windows Presentation Foundation. If you enable this policy setting you must select the visual experience for which you want to optimize Remote Desktop Services sessions. You can select either Rich multimedia or Text. If you disable or do not configure this policy setting Remote Desktop Services sessions are optimized for rich multimedia.

Allow . rdp files from valid publishers and user’s default . rdp settings

This policy setting allows you to specify whether users can run Remote Desktop Protocol (. rdp) files from a publisher that signed the file with a valid certificate. A valid certificate is one that is issued by an authority recognized by the client such as the issuers in the client’s Third-Party Root Certification Authorities certificate store. This policy setting also controls whether the user can start an RDP session by using default . rdp settings (for example when a user directly opens the Remote Desktop Connection [RDC] client without specifying an . rdp file). If you enable or do not configure this policy setting users can run . rdp files that are signed with a valid certificate. Users can also start an RDP session with default . rdp settings by directly opening the RDC client. When a user starts an RDP session the user is asked to confirm whether they want to connect. If you disable this policy setting users cannot run . rdp files that are signed with a valid certificate. Additionally users cannot start an RDP session by directly opening the RDC client and specifying the remote computer name. When a user tries to start an RDP session the user receives a message that the publisher has been blocked. Note: You can define this policy setting in the Computer Configuration node or in the User Configuration node. If you configure this policy setting for the computer all users on the computer are affected.

Specify SHA1 thumbprints of certificates representing trusted .rdp publishers

This policy setting allows you to specify a list of Secure Hash Algorithm 1 (SHA1) certificate thumbprints that represent trusted Remote Desktop Protocol (. rdp) file publishers. If you enable this policy setting any certificate with an SHA1 thumbprint that matches a thumbprint on the list is trusted. If a user tries to start an . rdp file that is signed by a trusted certificate the user does not receive any warning messages when they start the file. To obtain the thumbprint view the certificate details and then click the Thumbprint field. If you disable or do not configure this policy setting no publisher is treated as a trusted . rdp publisher. Notes:You can define this policy setting in the Computer Configuration node or in the User Configuration node. If you configure this policy setting for the computer the list of certificate thumbprints trusted for a user is a combination of the list defined for the computer and the list defined for the user. This policy setting overrides the behavior of the “Allow . rdp files from valid publishers and user’s default . rdp settings” policy setting. If the list contains a string that is not a certificate thumbprint it is ignored.

Prompt for credentials on the client computer

This policy setting determines whether a user will be prompted on the client computer to provide credentials for a remote connection to an RD Session Host server. If you enable this policy setting a user will be prompted on the client computer instead of on the RD Session Host server to provide credentials for a remote connection to an RD Session Host server. If saved credentials for the user are available on the client computer the user will not be prompted to provide credentials. Note: If you enable this policy setting in releases of Windows Server 2008 R2 with SP1 or Windows Server 2008 R2 and a user is prompted on both the client computer and on the RD Session Host server to provide credentials clear the Always prompt for password check box on the Log on Settings tab in Remote Desktop Session Host Configuration. If you disable or do not configure this policy setting the version of the operating system on the RD Session Host server will determine when a user is prompted to provide credentials for a remote connection to an RD Session Host server. For Windows Server 2003 and Windows 2000 Server a user will be prompted on the terminal server to provide credentials for a remote connection. For Windows Server 2008 and Windows Server 2008 R2 a user will be prompted on the client computer to provide credentials for a remote connection.

Configure server authentication for client

This policy setting allows you to specify whether the client will establish a connection to the RD Session Host server when the client cannot authenticate the RD Session Host server. If you enable this policy setting you must specify one of the following settings:Always connect even if authentication fails: The client connects to the RD Session Host server even if the client cannot authenticate the RD Session Host server. Warn me if authentication fails: The client attempts to authenticate the RD Session Host server. If the RD Session Host server can be authenticated the client establishes a connection to the RD Session Host server. If the RD Session Host server cannot be authenticated the user is prompted to choose whether to connect to the RD Session Host server without authenticating the RD Session Host server. Do not connect if authentication fails: The client establishes a connection to the RD Session Host server only if the RD Session Host server can be authenticated. If you disable or do not configure this policy setting the authentication setting that is specified in Remote Desktop Connection or in the . rdp file determines whether the client establishes a connection to the RD Session Host server when the client cannot authenticate the RD Session Host server.

Configure image quality for RemoteFX Adaptive Graphics

This policy setting allows you to specify the visual quality for remote users when connecting to this computer by using Remote Desktop Connection. You can use this policy setting to balance the network bandwidth usage with the visual quality that is delivered. If you enable this policy setting and set quality to Medium RemoteFX Adaptive Graphics uses an encoding mechanism that results in medium quality images. This mode consumes the lowest amount of network bandwidth of the quality modes. If you enable this policy setting and set quality to High RemoteFX Adaptive Graphics uses an encoding mechanism that results in high quality images and consumes moderate network bandwidth. If you enable this policy setting and set quality to Lossless RemoteFX Adaptive Graphics uses lossless encoding. In this mode the color integrity of the graphics data is not impacted. However this setting results in a significant increase in network bandwidth consumption. We recommend that you set this for very specific cases only. If you disable or do not configure this policy setting RemoteFX Adaptive Graphics uses an encoding mechanism that results in medium quality images.

Configure RemoteFX Adaptive Graphics

This policy setting allows the administrator to configure the RemoteFX experience for Remote Desktop Session Host or Remote Desktop Virtualization Host servers. By default the system will choose the best experience based on available nework bandwidth. If you enable this policy setting the RemoteFX experience could be set to one of the following options:1. Let the system choose the experience for the network condition2. Optimize for server scalability3. Optimize for minimum bandwidth usageIf you disable or do not configure this policy setting the RemoteFX experience will change dynamically based on the network condition. ”
