For security purposes, administrators set timeouts that log you off of a server after a certain number of hours and that lock a remote application after a certain number of minutes of inactivity.
With the View 6.0 remote applications feature, if you have not used a remote application for a certain amount of time, then 30 seconds before the application is automatically locked, you receive a warning prompt. If you do not respond, the application is locked. By default the timeout occurs after 15 minutes of inactivity, but your administrator can change the time period.
For example, if you have one or more applications open and you walk away from your computer, when you return an hour later, the application windows might no longer be open. Instead you might see a dialog box prompting you to click the OK button so that the application windows appear again.
The server timeout period is typically set for a certain number of hours of inactivity. By default, if you have Horizon Client open and connected to a particular server for more than 10 hours, you will be required to log in again. This timeout applies regardless of whether you are connected to a remote application or a remote desktop.
To configure these timeout settings, in View Administrator, go to Global Settings and edit the general settings.
