  • When a part of the source of an aggregated application is disabled, the application might be unexpectedly hidden from the end user.

    [#LC7675]

  • Attempts to disable the "Account Self-Service" option in StoreFront might not take effect, even though the option appears as disabled.

    [#LC7744]

  • Attempts to remove shared authentication from Stores in StoreFront might result in the following error message while saving the changes:

    "An error occurred while saving your changes."

    [#LC7781]

Universal Print Server

    [#LC7666]

User Experience

  • This fix provides improved support for sounds that play for a short period of time when using high quality audio.

    Note:

    • This fix does not take effect in sessions running on Windows Server 2008 R2.
    • For this fix to work, you must use Citrix Receiver 4.4 for Windows Long Term Service Release (LTSR) CU5 or later versions and the VDA version of XenApp and XenDesktop 7.6 LTSR CU4 or later.

    [#LC5842]

  • When performing an insert operation between two Microsoft Excel 2010 worksheets running on a Version 7.9 VDA, the Excel window might become unresponsive.

    [#LC7481]

  • In a multi-monitor environment, define the external monitor as the "Main Display" of Windows and position it to the right of the secondary laptop or tablet monitor in the display settings of the Control Panel. When you start a published application that appears on the external monitor and move this application to the tablet monitor or a laptop that is attached to the external monitor, opening or closing the lid of the tablet or a laptop can cause the published application to become black.

    To enable the fix, you must set the following registry key value on the VDA:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Ica\Thinwire
    Name: EnableDrvTw2NotifyMonitorOrigin

    [#LC6048]

  • After upgrading to PVS 7.11 from version 7.6, users in other domains might not be able to log on to the console.

    [#LC6216]

  • Server communication time out. In some cases, login times can become excessively long (for example, greater than 2 minutes). This can cause server timeout issues between the PVS Console and the SoapServer. By default, the timeout for such connections is 2 minutes. However, you can increase this value by modifying the registry value HOTKEY_LOCAL_MACHINE\Software\Citrix\ProvisioningServices ConnectionTimeout=<timeout in seconds>. If the login time is greater than approximately 4 minutes, users will also experience timeouts from the Microsoft MMC containing the PVS Console (these timeouts can be dismissed). 

    One cause for this issue is unreachable domains in Active Directory, where there is a 30 second timeout applied each time an attempt to connect to an unreachable domain is made. This can quickly add up to several minutes if there are multiple unreachable domains. In general, unreachable domains are created by adding a test or experimental domain to Active Directory, then removing it at a later time. Although the domain is gone, it is still reported by Active Directory when enumerating domains or authorization groups. 

    Unreachable domains can also be caused by a domain controller being temporarily shut down and disconnected from the network, so not all unreachable domains should be blacklisted.

    The best way to determine whether there are unreachable domains is by looking at the CDF trace for the PVS_DLL_ADSUPPORT module and checking for "Unreachable Domain" and "Server Referral" errors. If any of these are found, check the domains to ensure that they are not in use any more, and if not, add the domain names to the blacklist.

    The blacklist is a JSON format file called "%ProgramData\Citrix\Provisioning Services\blacklist.json". For example:
    {

    "Domains":

    [

    "sub.xs.local",

    "sb.xs.local"

    ]

    }

    where the two domains sub.xs.local and sb.xs.local will be excluded from domain and group enumeration. After the file is updated, you must restart the SoapServer and any running consoles in order to load the updated values.
