You can set group policies for options such as redirection of such things as audio, printers, ports, and other devices when you use the Microsoft RDP display protocol.
The following table describes the Remote Desktop Protocol (RDP) settings in the Horizon Client Configuration ADM template file. All RDP settings are User Configuration settings.
Determines whether audio information played on the remote desktop is redirected. Select one of the following settings:
This setting applies only to RDP audio. Audio that is redirected through MMR plays in the client.
|Enable audio capture redirection||
Determines whether the default audio input device is redirected from the client to the remote session. When this setting is enabled, the audio recording device on the client appears in the remote desktop and can record audio input.
The default setting is disabled.
|Bitmap cache file size in unit for number bpp bitmaps||Specifies the size of the bitmap cache, in kilobytes or megabytes, to use for specific bits per pixel (bpp) bitmap color settings.
Separate versions of this setting are provided for the following unit and bpp combinations:
|Bitmap caching/cache persistence active||Determines whether persistent bitmap caching is used (active). Persistent bitmap caching can improve performance, but it requires additional disk space.|
Specifies the color depth of the remote desktop. Select one of the available settings:
For 24-bit Windows XP systems, you must enable the Limit Maximum Color Depth policy inand set it to 24 bits.
|Cursor shadow||Determines whether a shadow appears under the cursor on the remote desktop.|
|Desktop background||Determines whether the desktop background appears when clients connect to a remote desktop.|
(Windows Vista or later) Determines whether desktop composition is enabled on the remote desktop.
When desktop composition is enabled, individual windows no longer draw directly to the screen or primary display device as they did in previous versions of Microsoft Windows. Instead, drawing is redirected to off-screen surfaces in video memory, which are then rendered into a desktop image and presented on the display.
|Enable compression||Determines whether RDP data is compressed. This setting is enabled by default.|
|Enable RDP Auto-Reconnect||Determines whether the RDP client component attempts to reconnect to a remote desktop after an RDP protocol connection failure. This setting has no effect if the Use secure tunnel connection to desktop option is enabled in View Administrator. This setting is disabled by default.|
|Font smoothing||(Windows Vista or later) Determines whether anti-aliasing is applied to the fonts on the remote desktop.|
|Menu and window animation||Determines whether animation for menus and windows is enabled when clients connect to a remote desktop.|
|Redirect clipboard||Determines whether the local clipboard information is redirected when clients connect to the remote desktop.|
|Redirect drives||Determines whether local disk drives are redirected when clients connect to the remote desktop. By default, local drives are redirected.
Enabling this setting, or leaving it unconfigured, allows data on the redirected drive on the remote desktop to be copied to the drive on the client computer. Disable this setting if allowing data to pass from the remote desktop to users' client computers represents a potential security risk in your deployment. Another approach is to disable folder redirection in the remote desktop virtual machine by enabling the Microsoft Windows group policy setting, Do not allow drive redirection.
The Redirect drives setting applies to RDP only.
|Redirect printers||Determines whether local printers are redirected when clients connect to the remote desktop.|
|Redirect serial ports||Determines whether local COM ports are redirected when clients connect to the remote desktop.|
|Redirect smart cards||Determines whether local smart cards are redirected when clients connect to the remote desktop.
Note: This setting applies to both RDP and PCoIP connections.
|Redirect supported plug-and-play devices||Determines whether local plug-and-play and point-of-sale devices are redirected when clients connect to the remote desktop. This behavior is different from the redirection that is managed by the USB Redirection component of the agent.|
|Shadow bitmaps||Determines whether bitmaps are shadowed. This setting has no effect in full-screen mode.|
|Show contents of window while dragging||Determines whether the folder contents appear when users drag a folder to a new location.|
|Themes||Determines whether themes appear when clients connect to a remote desktop.|
|Windows key combination redirection||Determines where Windows key combinations are applied.
This setting lets you send key combinations to the remote virtual machine or apply key combinations locally.
If this setting is not configured, key combinations are applied locally.
