    Session Timeout
    • Client Heartbeat Interval - Controls the interval between Horizon Client heartbeats and connected state. These heartbeats report to the broker the amount of idle time that has passed. Idle time occurs when no interaction occurs with the end-point device, as opposed to idle time in the desktop session. In large desktop deployments, setting the activity heartbeats at longer intervals might reduce network traffic and increase performance.
    • Client Idle User - Maximum time that a user can be idle while connected to the tenant. When this maximum is reached, the user is disconnected from all active application sessions. The user must reauthenticate to access the Horizon Client.
      Note: Set the Client Idle User timeout to be at least double the Client Heartbeat Interval to avoid unexpected disconnects from applications.
    • Client Broker Session - Maximum time that a Horizon Client instance can be connected to the tenant before its authentication expires. The timeout count starts each time you authenticate. When this timeout occurs, you can continue to work. If you perform an action that causes communication to the broker, such as changing settings, the system requires you to reauthenticate and log back in to the desktop.
      Note: The Client Broker Session timeout must be at least equal to the sum of the Client Heartbeat Interval and the Client Idle User timeout.
    • User Portal Timeout - How long you can be on the User Portal when you try to broker a connection before you must log in again.
    • Admin Portal Timeout - How much idle time can pass in the Administration Console before the session times out.
    Deletion Protection Dedicated Desktops (Desktops per Assignment per Hour) - This value controls the number of desktop VMs that can be deleted per hour in each of your dedicated desktop assignments. Select one of the following options from the drop-down menu.
    • Unlimited - Unlimited desktop VMs can be deleted from dedicated desktop assignments.
    • None - No desktop VMs can be deleted from any dedicated desktop assignment unless you allow them for a particular assignment using the Max Desktop Deletions (see note below).
    • Custom - Number of desktop VMs that can be deleted from a dedicated desktop assignment per hour. If you select Custom, you must also enter a numerical value to the right of this drop-down menu. You can allow additional desktop VMs to be deleted from a particular assignment using the Max Desktop Deletions (see note below).

    If you selected None or Custom, you can allow additional deletions for a particular assignment before this limit is invoked by editing the Max Desktop Deletions setting when you create or edit the assignment. If you have entered a value greater than 0 for the Max Desktop Deletions, then the system authorizes deletions of that number of VMs before counting them against the rate you set for Dedicated Desktops (Desktops per Assignment per Hour).

    For example, you might set Max Desktop Deletions to Custom with a value of 10 and set Dedicated Desktops (Desktops per Assignment per Hour) to Custom with a value of 1. In this case, after the first 10 VMs are deleted (no matter how long it takes for the count to reach 10), the system only allows 1 additional VM to be deleted per hour from that time forward.

    If you select Unlimited for Dedicated Desktops (Desktops per Assignment per Hour), there is no need to use the Max Desktop Deletions setting.

    For more information about the Max Desktop Deletions setting, see Create a Dedicated or Floating VDI Desktop Assignment.

    To prevent all VM deletions in a dedicated desktop assignment, use the Prevent Deletions setting on the Assignments page. See #GUID-EEB57473-6818-4F87-AD5E-B17C64C60834.

    HTML Access Cleanup credentials when the tab is closed - Controls whether to delete credentials of the broker session when an HTML Access portal connection tab is closed.
    RDSH Farm Defines policy parameters for RDSH farms.
    • Session Lifetime Reminder Message - This message reminds users that they will be logged off after a specified grace period.

      Default message is "Dear user, your session has reached the maximum lifetime, you will be logged off in {0} minutes". The value specified in the Grace Period text box replaces {0} in the message seen by the user.

    • Grace Period - Interval of time after which user is logged off following Session Lifetime Reminder Message.
    Desktop Assignment Options

    Use this setting to configure the displayed virtual desktops' names seen by your end users when they access their assigned virtual desktops using their end-user clients. This setting applies only to virtual desktops provisioned by a dedicated VDI desktop assignment. For information about desktop assignments, see Types of Assignments.

    Initially, when an end user logs in to their end-user client and sees a desktop newly provisioned from a dedicated VDI desktop assignment, the client displays the name of the dedicated VDI desktop assignment. At this time, a specific desktop virtual machine (VM) is not yet assigned to that end user as their dedicated desktop VM. When that end user takes the step to launch the virtual desktop for the first time, the system dedicates that specific desktop VM to that user as a result of that initial launch. Then for subsequent desktop launches, the name for that desktop that appears in that end user's client depends on the setting you select here.

    • When you change the setting, it can take up to 5 minutes for the update to take effect.
    • This option does not apply to end-user connections using Workspace ONE Access. When an end user uses Workspace ONE Access to access a desktop entitled to them from a dedicated VDI desktop assignment, Workspace ONE Access displays the assignment name and the user's Horizon Client and HTML Access portal displays the VM name for subsequent desktop launches.
    • When the toggle Enable Dedicated Desktop Assignment Name is turned off, the end user's client displays the name of the virtual desktop's underlying VM. Displaying the VM name is the legacy behavior.
    • When the toggle Enable Dedicated Desktop Assignment Name is enabled, the end user's client continues to display the name of the dedicated VDI desktop assignment that provisions the virtual desktop, even for subsequent desktop launches.
    Outbound Proxy Options Use Proxy - Allows you to configure an outbound proxy to access Internet services. To configure a proxy:
    1. Click Edit.
    2. Select Yes.

      Proxy configuration text boxes display.

    3. Enter information as follows.
      • Proxy - Hostname or IP address for your proxy server.
      • Port - Port number specified in your proxy server configuration.
      • Username - [Optional] Proxy authentication user name. Only required if the proxy requires authentication. Basic authentication is supported.
      • Password/Verify Password - [Optional] Proxy authentication user password. Only required if the proxy requires authentication. Basic authentication is supported.
      • Proxy Validation URL - URL to validate that the URL can be reached through the configured proxy. By default, is used.
    4. Click Test Proxy Status to verify that the validation URL can be reached through the configured proxy setting.
    Agent Updates Failure Threshold - The number of VMs for which automated agent update is allowed to fail before the update process is stopped. This prevents mass failures from occurring. The default value is 30. For more information, see Updating Agent-Related Software.
    Domain Security Settings Use these settings to prevent communication of Active Directory domain names to unauthenticated users using the various Horizon clients. These settings govern whether the Active Directory domain information is sent to the client and, if sent, how it is displayed in the end-user clients' login screens. For details, see #GUID-FE87529D-CF7F-464D-B74F-A21F19A22F54.
    Important: The combination of options selected here changes the user experience in the clients. Certain combinations can set requirements on how your end users specify their domain information in the client login screen, especially when using older clients, command-line clients, and when your environment is configured with multiple Active Directory domains. How these settings affect the client user experience depends on the client. You might need to balance your desired end-user experience according to your organization's security policies. For more information, see #GUID-FE87529D-CF7F-464D-B74F-A21F19A22F54.
