Server limits policy settings
The Server Limits section contains the policy setting for controlling idle connections.
Server idle timer interval
This setting determines, in milliseconds, how long an uninterrupted user session is maintained if there is no input from the user.
By default, idle connections are not disconnected (server idle timer interval = 0). Citrix recommends setting this value to a minimum of 60000 milliseconds (60 seconds).
To display the policy, select Multiple Versions, clear the Desktop OS versions, and then select Server Limits.
When this policy setting is used, an “Idle timer expired” dialog box might appear to users when the session has been idle for the specified time. Citrix policy settings don’t control this Microsoft dialog box message. For more information, see http://support.citrix.com/article/CTX118618.
