Fixes from Replaced Hotfixes

  1. At times of heavy logon/logoff activity, one or more of the following can be observed:

    • Applications can exit unexpectedly.
    • During logon attempts, an Error 1030 appears on the endpoint.
    • During logoff attempts, the Virtual Desktop Agent returns to the Logon screen and the endpoint continues to display the Desktop Viewer.

  2. Accessing certain Web sites with Internet Explorer and HDX MediaStream for Flash enabled can cause the Web page to become unresponsive, displaying only a cyan background.

  1. Server-side content fetching can exhibit poor performance in restrictive WAN conditions due to the lack of flow control in the Flash Virtual Channel. This fix corrects the flow control for the Flash Virtual Channel and provides smooth playback of Flash objects. For information about configuring server-side content fetching, see http://support.citrix.com/proddocs/topic/xendesktop-als/hd-flash-configure-server-ad.html.

    Note : To address this issue in its entirety, you must install hotfixes that contain Fix #LA0686 for each of the following:

    • Citrix Receiver
    • Virtual Desktop Agent
    • HDX MediaStream for Flash

    [From HDXFlash200WX64001][#LA0686]

  2. With server-side content fetching enabled, Flash content can take unexpectedly long (up to six minutes) to start rendering in the session.

    [From HDXFlash200WX64001][#LA1149]

  3. With HDX Mediastream for Flash enabled, opening and closing multiple tabs in Internet Explorer with Flash content can cause Internet Explorer to become unresponsive.
