Citrix aplication failed to start (progress bar disappearred)

Iff the Citrix server is behind a RODC, and there is a slow wan connection between user’s computer and RODC. Sometimes, the Citrix application can’t start:

    The session initially begins to connect as normal. After the loading dialog box disappears, the explorer application fails to appear.
    If the session is viewed in the Delivery Services console while the application is loading, it first shows as connecting, and later shows as disconnected until finally the session disappears.

Use the following registry key that allows you to configure the time-out as follows:

Name: ApplicationLaunchWaitTimeoutMS
Data: 99990 in dec
Note: Specifying a value of less than 10000 reverts to 10000 because 10 seconds is the minimum override.
