For security purposes, a Horizon administrator can set timeouts that log you off a server and lock a published application after some period of inactivity.

By default, you must log in again if you have Horizon Client open and are connected to a particular server for more than 10 hours. This timeout applies to both remote desktop and published application connections. You receive a warning prompt 30 seconds before a published application is locked automatically. If you do not respond, the published application is locked. By default, the timeout occurs after 15 minutes of inactivity, but a Horizon administrator can change the timeout period. For example, if you have one or more published applications open and you walk away from your computer, the published application windows might no longer be open when you return an hour later. Instead, you might see a dialog box that prompts you to click OK to re-authenticate to the server so that the published applications windows appear again.

You can configure the warning to be displayed before a user is forcibly disconnected and set the timer at which the warning is displayed. You can also configure the message that is displayed when the user is forcibly disconnected.

To configure these timeout settings in Horizon Console, select Settings > Global Settings, click the General Settings tab, and click Edit.

You can configure how running published applications behave when you reconnect to the server in Horizon Client.

For administrators - you can disable the published application reconnection behavior settings in Horizon Client, either from the command line, or by configuring a group policy setting. The group policy setting takes precedence over the command-line setting. For more information, see the -appSessionReconnectionBehavior option in Install Horizon Client From the Command Line, or the Disconnected application session resumption behavior group policy setting in Using Group Policy Settings to Configure Horizon Client.

For end users - an administrator can disable the published application reconnection behavior settings in Horizon Client.
  1. In the Horizon Client desktop and application selector window, right-click a published application and select Settings.
  2. In the Applications pane, select an application reconnection behavior setting.
