Group Policy Object (GPO) template

Scanner for Remote Desktop Server includes *.admx and *.adml administrative template files. These template files allow to configure the product via Local GPO and/or Domain-Based GPO. Please refer to Microsoft MSDN article on managing ADMX files.

GPO Editor

The archive file containing administrative template can be found in the installation directory: 

%ProgramFiles%\FabulaTech\Scanner for Remote Desktop (Server)\policies.zip

Additionally, the administrative template files are deployed to a local GPO during product installation and can be found here: 

%WINDIR%\PolicyDefinitions\Fabulatech.admx
%WINDIR%\PolicyDefinitions\ftscanrdpsrv.admx
%WINDIR%\PolicyDefinitions\en-US\Fabulatech.adml
%WINDIR%\PolicyDefinitions\en-US\ftscanrdpsrv.adml

It's recommended to use the GPO template files provided with the latest product version of Scanner for Remote Desktop Server.

The GPO template can be used to configure the following settings:

Setting Description
Disable functionality
(Computer only)

This policy setting is used for disabling scanner redirection functionality.

If this policy setting is enabled, scanners cannot be redirected and do not appear in the scanner menu.

If this policy setting is disabled or not configured, scanner redirection works and scanners appear in the scanner menu.

Lock Config
(Computer only)

This policy setting is used for locking the settings user interface of the program.

If this policy setting is enabled, the user interface containing the program settings is locked and the user can't change settings in the tray menu.

If this policy setting is disabled or not configured, the user interface containing the program settings is accessible for users.

Hide Webcam

This policy setting controls whether webcam devices can be used as source for virtual TWAIN scanner.

If this policy setting is enabled, webcams will not appear in the scanner selection menu.

If this policy setting is disabled or not configured, the webcams can be used as sources and will appear in the scanner selection menu.

Notes:
If the policy is configured at the User level (HKCU), users can change the webcam hide mode at any time through the user interface.
If the policy is configured at the Computer level (HKLM), it overrides the user-level setting for all users of the computer. In this case, users cannot change the webcam hide mode through the user interface.

Default Color Mode

This policy allows to override default scanning color mode (e.g. Color or Grayscale).

This is really useful in cases if scanning application scans without displaying Scanning Preferences dialog and does not allow to configure color mode internally also.

Default Resolution This policy allows to override default scanning resolution (in DPI).
Default Duplex

This policy allows to override default scanning mode (Simplex or Duplex).

Pay attention when setting up Duplex since scanning application should support Duplex scanning and request two pages from scanner.

Default Auto Rotate

TWAIN ONLY. This policy allows to override the default page auto-rotate mode (Enabled or Disabled).

If enabled, the logic depends on intelligent features within a scanner driver to automatically rotate the image in order to the correct position. i.e. the scanner driver decides if the page should be rotated (90 or 180 degrees, CW or CCW).

Default Auto Deskew

TWAIN ONLY. This policy allows to override the default page auto-deskew mode (Enabled or Disabled).

If enabled, the logic depends on intelligent features within a scanner driver to automatically straightening an image.

Default Auto Border Detection

TWAIN ONLY. This policy allows to override the default page auto-border-detection mode (Enabled or Disabled).

If enabled, the logic depends on intelligent features within a scanner driver to automatically detect the scanned image borders and crop the image correspondingly.

Default Auto Discard Blank Pages

TWAIN ONLY. This policy allows to override the default auto discard blank page mode. If you enable this policy setting, auto discard blank page capability will be set before each scan.

  • All Pages – indicates that all images will be delivered to the Application, none of them will be discarded.
  • Auto – if this is used, then the scanner driver will decide if an image is blank or not and discard as appropriate.
Default Scanner

This policy setting manages scanner auto-selection mode at session log-in. The following auto-selection modes are available:

  • None – do not select any scanner automatically.
  • Autoselect – automatically select the connected scanner.
  • Last used – automatically select the last used scanner.
  • Specified – select the scanner defined in the "Specified scanner" field.

If enabled, the scanner auto-selection mode will be enforced according to this policy setting. If disabled or not configured, Autoselect mode is used.

Notes:
If the policy is configured at the User level (HKCU), users can change the Default Scanner settings at any time through the user interface.
If the policy is configured at the Computer level (HKLM), this setting overrides user-level preferences for all users on the computer. In this case, users cannot change the Default Scanner settings via the user interface.

Compression

This policy setting is used for setting image compression rate during its transfer to the Server side. The following compression modes are used:

  • Disable – image compression is disabled;
  • Lossless – lossless(zlib) compresison is used without loss of image quality;
  • JPEG – JPEG compression is used with loss of quality. The level of image quality is specified in the "JPEG compression quality" field.

If this policy setting is enabled, the compression mode for the user will be set by this policy setting.

If this policy setting is disabled or not configured, the "JPEG" compression mode will be used.

The user has the possibility to change the compression mode at any time via the settings interface, even if the policy setting is enabled.

Licensing
(Computer only)

This policy setting is used for licensing management. The following licensing modes are used:

License Key
use the specified license key for each product server;
License Server
use a license server for centralized management of licensing;

For "License Key" type of licensing you must specify a string of the key in the corresponding field.

For "License Server" type of licensing you must specify a license server name in the name_or_ip:port format, where the port is an optional parameter.

If this policy setting is enabled, the licensing mode will be overridden by this policy setting. It means using GPO License key instead key that determined via the settings interface.

If this policy setting is disabled or not configured, the licensing mode is determined via the settings interface.

Bandwidth Limit

This policy setting specifies the maximum allowed bandwidth, in KiloBytes per second, for transferring scanned data to a user session.

If zero or not specified, no limitation.

Scanning Settings dialog location

This policy determines where the scanning settings dialog will appear: either on the Server side, or on the Workstation side.

  • If Server, FabulaTech Scanner Settings dialog appears on Server side.
  • If Workstation, vendor-native scanning dialog appears on Workstation side.
Force the TWAIN Scanning Settings dialog This policy allows to force displaying the TWAIN Scanning Settings dialog even if a scanning application does not display the scanning dialog.
Twain Appearance Mode

This policy allows to configure Virtual TWAIN Scanner appearance behavior.

  • Auto – Make Virtual TWAIN Scanner datasource unavailable if the source scanner is not selected or not available.
  • Always Available – Virtual TWAIN Scanner datasource is always available.

If this policy is Disabled or Not Configured, then Auto mode is used.

Use vendor defined names for TWAIN scanners Use this option if your scanning software requires specific hardware for operation.
Show TWAIN scanner selection dialog
(Computer only)

This policy setting is used for showing the TWAIN scanner selection dialog before each scan.

If this policy setting is enabled, the TWAIN scanner selection dialog will be shown before every scan if more than one TWAIN scanner is present on the client side.

If this policy setting is disabled or not configured, the scanner selection dialog will not be shown. Instead, the user should choose the needed scanner in the tray menu.
