Group Policy Object (GPO) template

This policy setting is used for disabling webcam redirection functionality.

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

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

If this policy setting is used for the computer, it overrides the policy setting for all users of this computer.

This policy setting controls whether update subscription expiration notifications are displayed.

If Enabled, the update subscription expiration notifications will not appear.

If Disabled, the update subscription expiration notifications will appear.

If Not Configured, the notification mode is determined by the corresponding user policy setting or the user interface setting.

This policy setting overrides any user-configured preferences, meaning users cannot change the update subscription notification mode through the user interface.

This policy setting is used for disabling audio redirection functionality.

If this policy setting is enabled, audio redirection will be disabled for all users of this computer.

If this policy setting is disabled, audio redirection will be enabled for all users of this computer.

Also this policy setting overrides similar policy setting for all users of this computer and users will not be able to change audio redirection mode via the settings interface.

If this policy setting is not configured, the audio redirection mode is determined by the similar user policy setting or via the settings interface.

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.

This policy setting allows you to manage the video compression type used. The following compression options are available:

• VP8 – Uses the VP8 codec for compression. You can specify a VP8 Stream Bitrate in the corresponding field.
• MJPEG – Uses the MJPEG codec for compression. You can specify an MJPEG Quality in the corresponding field.

If this policy setting is enabled, user-configured settings are overridden, and users cannot change them through the user interface.

If this policy setting is disabled or not configured, the compression type is determined through the settings interface.

Note: If this policy setting is applied at the computer level, it overrides the same policy setting applied at the user level for all users of this computer.

This policy setting controls advanced log file rotation behavior. The product may create multiple logs for each user, depending on factors such as Session ID, Process ID (PID), and FabulaTech product module. Each log is stored on disk as a set of log file parts, which are created as the log is rotated. When the active log file part reaches the configured size limit, it is rotated: the current file part is renamed, and a new empty file part is created for the same log. If any of the configured limits are exceeded, the oldest log file parts are automatically removed according to the configured rules.

Maximum log file part size (per file), MB

Range: 50-1000
Specifies the maximum size, in megabytes, of a single log file part. When a log file part exceeds this value, the file is rotated and a new file part is created for the same log.

Maximum log file parts (per log)

Range: 1-99
Specifies the maximum number of log file parts allowed for each individual log. If this limit is exceeded, the oldest file part belonging to that log is removed. If set to 1, only a single log file part is kept. When the maximum file size is reached, the file part is overwritten.

Maximum log file parts (global)

Specifies the maximum total number of log file parts stored on disk across all logs and all users. If this limit is exceeded, the oldest log file parts are removed, regardless of which log they belong to. If 0, no global limit is applied; an unlimited number of log file parts is allowed.

If this policy is disabled or not configured, log file rotation behavior is controlled by the application’s internal log rotation settings.

Log Level

Range: 0–10
This policy setting configures the log level, which determines which events are written to the log files. This setting is intended for troubleshooting purposes and is typically enabled at the request of the FabulaTech technical support team.

The following values are supported:

• 0 - Error
• 1 - Warning
• 2 - Information
• 3 - Debug
• 4 - Dump
• 5–10 - Reserved

If this policy is disabled or not configured, the log level is controlled by the application’s internal logging settings.

This policy setting determines whether the application is allowed to check for updates and notify the logged-on user.

Enabled:
Disables the "Check for updates" feature. The application will not check for updates and users will not receive update notifications.

Disabled:
Enables the "Check for updates" feature. The application can check for updates and notify users when updates are available.

Not Configured:
The application’s local settings determine whether it checks for updates and notifies the user.

Note: If this policy setting is applied at the FabulaTech level, it overrides the same policy setting applied at the product level for all installed FabulaTech products.

This setting is common for multiple FabulaTech products, including USB for Remote Desktop, Sound for Remote Desktop, and Webcam for Remote Desktop.

This policy setting defines how redirected audio devices are isolated across user sessions in a multi-user environment. This setting is relevant when multiple users are logged on to the same server simultaneously and multiple audio devices are present.

FabulaTech isolates audio devices within user sessions so that only the owning user can access the redirected device. To provide isolation, the program relies on a dedicated FabulaTech isolation driver. If the isolation driver is disabled or uninstalled (for example, by an administrator or security software), audio isolation may be affected. As a result, an audio device may become accessible from another user session.

Important: The audio device isolation mode is determined when a user session starts. If this policy setting is changed, existing user sessions are not affected. Users must sign out and sign in again for the new isolation mode to take effect.

To address such scenarios, the following isolation modes are available:

Strict

Provides the highest level of isolation. Audio devices are isolated and accessible only to their owner.

If the isolation driver is disabled or becomes inactive, the audio device immediately becomes unavailable to all users.

Important: Native Remote Desktop audio redirection is not supported in this mode.

This mode is recommended for environments that require maximum session separation and where native audio redirection is not required.

Session-isolated (compatible)

Provides session-based isolation with a compatibility fallback. By default, audio devices are isolated and accessible only to their owner. Native Remote Desktop audio redirection is supported in this mode.

If the isolation driver is disabled or becomes inactive, the audio devices remain accessible globally (without isolation).

This mode is the only option that allows native and FabulaTech audio redirection to be used together.

No isolation

No session isolation is applied. Audio devices are accessible to all logged-on users.

This mode is not recommended for multi-user environments.

It should only be used in special scenarios, such as single-user systems where concurrent sessions are not possible.

If this policy setting is Disabled or Not Configured

The audio isolation mode is controlled by the local settings of the corresponding FabulaTech device redirection software (Sound for Remote Desktop, Webcam for Remote Desktop, or USB for Remote Desktop).
