L-series Windows logon screen disconnects after 2 minutes

Symptom:

Windows has a default setting that forces the logon screen to time out and disconnects from the server after 2 minutes. If the L-device has auto-connect enabled, the device can repetitively cycle between the NComputing server selection screen and the Windows logon screen every 2 minutes, if an L-series user does not manually log into a Windows session. This excess cycling activity can lead to much higher than normal network activity and spiral into a network or host failure.

Cause:

Windows implements a 2 minutes timeout to prevent many login screens begin active for a long period.

Solution:

To work around this timeout, you can activate the default logon screen screensaver for less than 2 minutes. If the screen saver launches before this 2-minute timeout, there will not be a premature disconnect.

The default setting in the registry "ScreenSaveTimeOut" under" ([HKEY_USERS.DEFAULTControl PanelDesktop]) for the logon screen screensaver is 600 seconds. Change this setting to 119 seconds or less and the problem should be resolved. Also note that changing this setting will not affect personal profile settings related to any screen savers. This will only affect the logon screen.
