Issues fixed since XenApp and XenDesktop 7.6 LTSR

May 10, 2017

XenApp/XenDesktop 7.6 LTSR Cumulative Update 1 addresses the following issues reported since the release of XenApp and XenDesktop 7.6 LTSR.

For a list of all issues fixed since the release of XenApp and XenDesktop 7.6, see Issues fixed since XenApp and XenDesktop 7.6.

Citrix Director

  • User name searches in Director can experience random delays of up to two minutes.

    [#LC1250]

  • When attempting to export a large amount of data in PDF format, the server’s CPU and memory consumptions can approach 100% and the following error message appears:

    “Action failed. Data source unresponsive or reported an error. View server event logs for further information.”

    This fix introduces a configurable limit for the PDF export and as a result, at least a portion of the report can be obtained.

    After installing this fix, you must configure the web.config file in the wwwroot\Director folder as follows:

    Add the following line to “appSettings” section:

    <add key=”UI.ExportPdfDrilldownLimit” value=”100”/>

    The limit depends on the capability of the server, such as the memory size where the value specifies the count of rows in the PDF report.

    [#LC4108]

  • Attempts to export reports in any file format might fail with the following error message:

    “Action failed. Unexpected server error. View server event logs for further information.”

    [#LC4281]

  • If a XenApp server has two IP addresses and the DNS server cannot resolve the first IP address, attempts to log on to Citrix Director by an administrator might fail with the following error message:

    “The system is currently unavailable. Please try again later or contact your administrator.”

    [#LC4411]

  • When attempting to export a large amount of data in CSV format, a timeout can occur and the export might fail with the following error message:

    “Action failed. Data source unresponsive or reported an error. View Director server event logs for further information.”

    This fix lets you configure the timeout value for exporting data.

    After installing the fix, you must configure the web.config file in the wwwroot\Director folder as follows:

    Add the following line to “appSettings” section: < add key=”Connector.DataServiceContext.Timeout” value=”3600” /> where the value specifies the timeout in seconds.

    [#LC4467]

  • Selecting a user to display that user’s session details can result in the user name that appears in the top left corner to show as “NULL.”

    [#LC4589]

  • If the NetBios domain name contains an ampersand (&), shadowing from the Citrix Director console might fail. This issue occurs because the ampersand character is a reserved character in XML and can cause the parsing for the current logon to fail.

    [#LC4633]

Citrix Policy

  • The Microsoft Management Console (MMC) fails if the “Console Root” is not selected in the navigation pane when closing Desktop Studio.

    [#LC1314]

  • The Citrix Policy Engine might cause the server to become unresponsive. When this occurs, Citrix Receiver and RDP connection requests fail.

    [#LC1817]

  • With this enhancement, modeling reports created by the Citrix Group Policy Modeling wizard appear in Citrix Studio’s middle pane.

    [#LC2189]

  • When adding or creating a Citrix Administrator in Citrix Studio with a user or group that contains an underscore in the name, such as get\dl_lab_group, the first underscore does not appear in the details of the list of administrators. The name appears as dllab_group.

    [#LC2284]

  • When running the Group Policy Modeling wizard on the policies node of AppCenter as a domain user, applied user and computer policies might not be visible.

    [#LC3284]

  • Citrix Director administrators might not be able to view Citrix policies in session details.

    [#LC3941]

  • Attempts to add multiple session printers to a group of user devices under the “Printer assignments” window fails to expand and display the scrollbar. As a result, attempts to add multiple session printers to a group of user devices can fail.

    [#LC4658]

Citrix Studio

  • This fix addresses a security vulnerability. For more information, see Knowledge Center article CTX213045.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC2350]

  • This fix addresses a memory leak in Citrix Studio that occurs while running App-V app discovery.

    [#LC2559]

  • When using the Machine Creation Service to catalog VDAs for Server OS, unavailability of personal vDisk storage can incorrectly set the “CleanOnBoot” property of the catalog to “False.” As a result, the catalog might fail to update.

    [#LC2959]

  • When two applications have the same ApplicationID, refreshing App-V applications can cause Citrix Studio to set the App-V package name incorrectly.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC2969]

  • Citrix Studio might become unresponsive while closing PowerShell resources.

    [#LC3612]

  • Creating multiple applications in multiple folders under Delivery Groups in Citrix Studio might result in a large folder structure. The first time you open Citrix Studio and click folders or applications, the folders or applications might be dragged instead of being selected. This moves the selected object and causes the folder or application structure to change.

    [#LC3705]

  • The Add-XDController cmdlet does not assign full custom database connection strings to the Controller.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC3860]

  • Attempts to open Citrix Studio by users that are not members of the Database administrators user group can result in permission errors on the SQL Server.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4127]

  • Attempts to provision additional resources to a multi-tenant offering in App Orchestration 2.6 can fail if the offering already contains two or more tenants.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4170]

  • When multiple Citrix Studio sessions are open, policy changes made in one session can be lost and overwritten by those made in another.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4487]

Controller

  • This fix addresses a security vulnerability. For more information, see Knowledge Center article CTX213045.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC0559]

  • When two or more instances of event ID 3012 record in the event log, event IDs 3020 and 3021 also appear in the log and the messages are incorrect. With this fix, if two or more instances of event ID 3012 record, then event IDs 3010 and 3011 correctly appear in the log.

    [#LC1425]

  • The error messages for event IDs 1110 and 1111 are incorrect in the event log. With this fix, the following correct messages appear in the event log:

    • EventID:1110: To avoid excessive event logging, the service is temporarily suppressing related messages (event IDs 1100-1109, 1112-1116).
    • EventID:1111: The service is no longer suppressing related messages (event IDs 1100-1109, 1112-1116).
       

    [#LC1485]

  • If the NetBios domain name contains an ampersand (&), attempts to start Citrix Studio fail with the error “You are not authorized to perform this operation” with the code XDDS:72182E6B.

    [#LC1646]

  • In some Active Directory organizational units (OUs), if the OU name contains a special character, the core services for XenDesktop (such as AD Identity Service or Broker Service) might not be able to bind to the OU. This can cause the CPU usage to be higher than normal. Additionally, Citrix Studio might become inaccessible as the services might close unexpectedly.

    [#LC1979]

  • When using filtering by keywords for published applications, the workspace control might not work.

    [#LC2025]

  • When you consolidate XenApp and XenDesktop licenses that have the same Subscription Advantage expiry dates into a single license file, some XenApp licenses might be missing from the license information visible in Studio.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC2350]

  • A published application name that contains a trailing space can result in several issues. These issues occur when generating browser names from the published name of the application that has truncated names containing a trailing space.

    [#LC2897]

  • When two applications have the same ApplicationID, refreshing App-V applications can cause Citrix Studio to set the App-V package name incorrectly.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC2969]

  • When executing Set-BrokerDBConnection and related commands, the associated configuration logging entries in Citrix Studio list the corresponding “Main Task” with a status of “In Progress,” and the status is not updated when the task completes.

    [#LC3479]

  • After performing an upgrade to XenDesktop 7.6 using the local system account (typically used by Electronic Software Distribution such as SCCM), the Analytics Service fails to start.

    [#LC3493]

  • Performing a scheduled restart of a VDA for Server OS that is connected to a VMware Vsphere Hypervisor can cause the server to shut down and remain in a powered off state.

    • To enable the fix, set the following registry key:
      HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DesktopServer\RebootSchedule Name: ShutdownTimeoutRecovery Type: DWORD Value: 1
    • To disable the fix, set the following registry key:
      HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DesktopServer\RebootSchedule Name: ShutdownTimeoutRecovery Type: DWORD Value: 0

    After setting the value, you must restart the Broker Service.

    [#LC3807]

  • The Add-XDController cmdlet does not assign full custom database connection strings to the Controller.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC3860]

  • Attempts to open Citrix Studio by users that are not members of the Database administrators user group can result in permission errors on the SQL Server.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4127]

  • Attempts to provision additional resources to a multi-tenant offering in App Orchestration 2.6 can fail if the offering already contains two or more tenants.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4170]

  • When the setting “SupportMultipleForest” is enabled on the Controller to allow NTLM authentication, the Linux VDA might fail to complete the registration process as its Service Principal Name (SPN) might not be set in the EndpointReference of the Windows Communication Foundation (WCF).

    [#LC4235]

  • If you create virtual machines (VMs) that are hosted on a VMware hypervisor, initial attempts to update or delete those VMs from Citrix Studio can fail with an “Error ID XDDS:B125B84A,” but subsequent attempts succeed.

    [#LC4436]

  • When multiple Citrix Studio sessions are open, policy changes made in one session can be lost and overwritten by those made in another.

    Note: To enable this fix, you must update both Citrix Studio and the Controller components with 7.6 LTSR Cumulative Update 1.

    [#LC4487]

  • When running the PowerShell command “Get-LogSummary” for a date range that encompasses a switch to or from daylight saving time, the following error message appears:

    “An item with the same key has already been added.”

    The issue occurs when daylight saving time introduces ambiguous local dates or times. As a result, duplicate entries are created in the HashMap and an exception occurs.

    This fix introduces a message to inform users to split the time span to account separately for the point in time when daylight saving time begins or ends.

    [#LC4612]

  • Attempts to update machine catalogs in Amazon Web Services (AWS) environments can fail intermittently. To enable the fix, you must run the command, “Set-ProvServiceConfigurationData –Name ImageManagementPrep_DoImagePreparation –Value $false” for the image preparation phase to be skipped during the machine catalog update.

    [#LC4709]

  • Controllers occasionally lose connectivity with the database when there is a high number of apps and VDA processes running. When that happens, VDAs remain in the initialization state and applications are unavailable.

    [#LC4848]

  • When there are too many hypervisor alerts, the SQL database server’s CPU usage can reach 100%.

    [#LC5277]

  • Under high utilization conditions (more than 5,000 users launching numerous apps on numerous VDAs for Server OS concurrently), the SQL database server’s CPU usage can reach 100%, which causes outages and apps are unable to launch.

    [#LC5315]

HDX MediaStream Flash Redirection

  • If HDX MediaStream Flash Redirection is enabled, opening and closing multiple tabs in Internet Explorer with Flash content can cause Internet Explorer to exit unexpectedly.

    [#LC0375]

  • With HDX MediaStream for Flash enabled, opening and closing multiple tabs in Internet Explorer can cause Internet Explorer to close unexpectedly.

    [#LC1141]

  • When browsing websites with HDX MediaStream Flash Redirection enabled, the Flash redirection feature fails if the registry value of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs is set to just “mfaphook.dll” or “mfaphook64.dll” instead of the full path to “mfaphook.dll” or “mfaphook64.dll.”

    [#LC4388]

Installer

  • If you install version 7.6.300 of the VDA from the command line, the /noreboot switch - depending on its location in the string of switches - is not being honored. As a result, the VDA restarts after the installation completes.

    [#LC4046]

  • When installing a VDA, certain registry keys for performance might be installed even if you disable the “Optimize Performance” option during installation.

    [#LC4330]

Licensing

  • Citrix Studio displays the licensing models in Spanish for license servers set to a French system locale.

    [#LC3450]

Provisioning Services

   
Console Target Device
Server  

Console

  • After installing Provisioning Services Console version 7.1.3, many .NET applications fail on Windows Server 2008 R2 and on Windows 7.

    [#LC1838]

  • The XenDesktop Setup Wizard might fail to create machine when the VMware ESX host is in Maintenance Mode.

    [#LC3401]

  • The XenDesktop Setup Wizard might fail to honor the “Superseded” flag on the Personal vDisk storage of the hosting unit.

    [#LC3573]

  • When the Streamed VM Setup Wizard is running, enumerating templates on the VMware ESX cluster that contain many hosts and data stores can take a long time to complete.

    [#LC3674]

    [#LC3723]

  • The following error message can appear while creating machines using the Streamed VM Setup Wizard:

    “Object reference not set to an instance of an object.”

    [#LC3811]

  • When a help desk administrator creates new virtual machines (VMs) from a standalone Provisioning Services Console through the XenDesktop Setup wizard, attempts to start a target device from a BDM partition can fail and cause an incorrect IP address for the logon server to appear.

    [#LC3911]

  • Installing the Provisioning Services Console sets the following registry key to “ 1.” This can cause other .NET applications to try to use the wrong version of the Framework and possibly fail:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework Name: OnlyUseLatestCLR Type: REG_DWORD Data: 1

    [#LC4197]

  • Attempts to create virtual machines (VMs) by using the XenDesktop Setup wizard or the Streamed VM Setup wizard might fail in a Microsoft System Center Virtual Machine Manager (SCVMM) environment. With this fix, the fully qualified domain name (FQDN) of the host is used in the commands instead of short name.

    [#LC4230]

  • The XenDesktop Setup wizard might fail to create Provisioning Services target devices in System Center Virtual Machine Manager (SCVMM) 2012 environments.

    [#LC4256]

  • Attempts to connect to VMware Vsphere Hypervisor 5.1 by using the Streamed VM Setup wizard or the XenDesktop Setup wizard fail if User1 and User2 are configured to use different ports.

    To use a different port to connect to the VMware ESX server, you must create the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ProvisioningServices\PlatformEsx Name: Port Type: DWORD Value: <port_number>

    [#LC4283]

  • SSL connections between the XenDesktop Setup wizard and XenServer fail.

    [#LC4377]

  • This is an enhancement to facilitate NIC teaming with the latest Mellanox NICs and firmware used in HP Moonshot systems.

    [#LC4646]

  • If the template created in System Center Virtual Machine Manager (SCVMM) has NICs on two different networks - for example, NIC1 on network xxx and NIC2 on network yyy - the XenDesktop Setup wizard default behavior is to change both NICs to the network of the host record (network zzz). For the NIC2 network to remain unchanged, after installing this fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ProvisioningServices\PlatformScvmm Name: RequireMatchingNetworks Type: REG_DWORD Value: 1

    [#LC4650]

  • Pressing “Ctrl+C” without any items selected, the Provisioning Services Console might exit unexpectedly with the following error message:

    “MMC has detected an error in a snap-in and will unload it.”

    Additionally, the issue can occur if the “Ctrl+C” key combination is automatically injected by certain third-party software.

    [#LC4909]

Server

  • When using a BDM partition, target devices running on VMware do no attempt to log on to all servers in the list if the top-most server is unreachable.

    [#LC3805]

  • Attempts to mount a vDisk on a Provisioning Server fail unless the server has logical access to the vDisk.

    [#LC3835]

  • When a help desk administrator creates new virtual machines (VMs) from a standalone Provisioning Services Console through the XenDesktop Setup wizard, attempts to start a target device from a BDM partition can fail and cause an incorrect IP address for the logon server to appear.

    [#LC3911]

  • When exporting a vDisk by running the PowerShell command “Mcli-Run ExportDisk -p DiskLocatorName=”DISK_NAME”, StoreName=”STORE_NAME”, SiteName=”SITE_NAME,”” a manifest file with multiple entries for each version of the vDisk might be created. The issue occurs when a vDisk with the same name is present in multiple Sites. The number of duplicate entries per version corresponds to the number of sites that have the vDisk.

    [#LC4225]

  • Machine creation fails with the XenDesktop Setup wizard in SCVMM environments if there is a trailing backslash (\) at the end of the VM storage path.

    [#LC4418]

  • This is an enhancement to facilitate NIC teaming with the latest Mellanox NICs and firmware used in HP Moonshot systems.

    [#LC4646]

  • If the template created in System Center Virtual Machine Manager (SCVMM) has NICs on two different networks - for example, NIC1 on network xxx and NIC2 on network yyy - the XenDesktop Setup wizard default behavior is to change both NICs to the network of the host record (network zzz). For the NIC2 network to remain unchanged, after installing this fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ProvisioningServices\PlatformScvmm Name: RequireMatchingNetworks Type: REG_DWORD Value: 1

    [#LC4650]

Target Device

  • Provisioning Services Target device installation on systems with ESX VMXNET3 Nics requires Microsoft hotfix https://support.microsoft.com/en-us/kb/2550978 or a superseding hotfix to be installed. With this fix, rather than requiring KB2550978 explicitly, a warning message appears, advising administrators to make sure KB2550978 or a superseding hotfix is installed.

    [#LC3016]

  • The PVS Device Service (BNDevice.exe) might not start successfully when the service logon account is set to “Local System,” which is the default value.

    [#LC3209]

  • The logging level of some critical error logs that are related to Active Directory password change might not be set correctly and as a result, the logs are not sent to the server for Citrix Diagnostic Facility tracing.

    [#LC3803]

  • Automatic vDisk Updates do not run inventory updates on PvD enabled vDisks.

    [#LC3997]

  • ESX target devices utilizing a VMXnet3 network driver can experience a fatal exception, displaying a blue screen when using jumbo frames (frames with more than 1500 bytes of payload per frame).

    [#LC4238]

  • Provisioned target devices have a 96 hour license grace period after which they shut down if no valid licenses are available. With this enhancement, the licensing grace period for target devices is extended to 30 days (720 hours).

    [#LC4645]

Session Recording

   
Agent Player

Agent

  • With “Allow third party applications to record custom data on this VDA machine” enabled in the Session Recording Agent properties, the Session Recording Agent Service running on a Japanese language Windows operating system might fail to start and client sessions cannot be recorded.

    [#LC3861]

Player

  • Recordings of Microsoft Paint sessions do not play back correctly in the Session Recording Player.

    [#LC4389]

  • An error occurs when you play back a session that was recorded on a multiple-monitor user device.

    [#LC4391]

StoreFront

  • This fix addresses inconsistencies in the Japanese translation of the term “Classic” in the Management Console user interface.

    [#LC3607]

  • When you click to launch a second or subsequent application, one or more instances of the first application you started can launch. The issue occurs when using a version of Receiver other than Citrix Receiver for Web when multiple-site aggregation is configured. An additional instance of the first application launches from each aggregated Site.

    [#LC4278]

  • Customizations for published desktops you make in the default.ica file might not be honored. For example, you might not be able to see the connection bar inside certain desktops even if you set “ConnectionBar=1.”

    [#LC4688]

  • In certain scenarios, StoreFront generates enumeration responses that contain duplicate resources. This can cause Receiver for Web to report a failure and the apps might fail to appear. The issue occurs with one or more of the following conditions:

    • A farm is referenced by more than one UserFarmMapping in a multi-Site configuration.
    • The user belongs to Active Directory Groups wherein multiple UserFarmMapping are applied.
    • The EquvalentFarmSets that contain farms have no aggregation group, or there is a Delivery Group with multiple assignments for the user.
       

    [#LC4863]

Universal Print Server

   
Client Server

Client

  • Attempts to manage ports or printers on the remote print server from the Microsoft Print Management console on a VDA for Server OS might fail with the following error message: “Failed to complete the operation. This operation is not supported.” Also, when navigating to the Ports tab, ports might not be listed.

    Additionally, when you right-click any printer and select “Open Printer Queue,” the following error message might appear:

    “Windows can’t find the printer. Make sure the network is working and you’ve entered the name of the printer and print server correctly.”

    To address this issue, delete the following registry key “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Providers\Universal Printer” from the registry of the VDA and restart the Print Spooler Service. The ports are enumerated correctly in the Microsoft Print Management Console and you can configure the ports and printers.

    [#LC3740]

Server

  • Batch printing using the Microsoft GDI Print API can fail to where the last page does not print, and the following error message appears:

    “Dispatch::CDriverTripSummary::PrintReport, Error Occured While Printing….Check Printer”

    [#LC3920]

  • This fix introduces support for Citrix UPS Print Driver Certification Tool for Universal Print Server 7.6.300. For more information, see Knowledge Center article CTX142119.

    “Could not perform this operation because the default mail client is not properly installed.”

    The issue does not occur in console or Remote Desktop sessions.

    [#LC3701]

HDX 3D Pro

  • In HDX 3D Pro dual-monitor configurations, locking Windows on one monitor can fail to blank the screen on the second monitor. The issue occurs after disconnecting from a dual-monitor client session, then reconnecting from a single monitor client, then disconnecting from the session, then reconnecting from the dual-monitor client.

    [#LC3934]

  • The mouse pointer might not assume the proper shape when the mouse is positioned at the edge of a Microsoft Notepad application window.

    To enable this fix, you must set the following registry key:

    • On 32-bit Windows:
      HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HDX3D Name: EnableUnknownCursorHandling Type: REG_DWORD Value: 1
    • On 64-bit Windows:
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HDX3D Name: EnableUnknownCursorHandling Type: REG_DWORD Value: 1  

    [#LC4160]

  • Attempts to resize the session screen resolution can fail intermittently, leaving the DesktopViewer window grayed out.

    [#LC4261]

  • With HDX 3D Pro enabled, customized mouse pointers in 3D graphics rendering applications might appear incorrectly.

    [#LC4713]

    [#LC0375]

  • With HDX Mediastream for Flash enabled, opening and closing multiple tabs in Internet Explorer can cause Internet Explorer to close unexpectedly.

    [#LC1141]

  • When browsing websites with HDX MediaStream Flash Redirection enabled, the Flash redirection feature fails if the registry value of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs is set to just “mfaphook.dll” or “mfaphook64.dll” instead of the full path to “mfaphook.dll” or “mfaphook64.dll.”

    [#LC4388]

HDX MediaStream Windows Media Redirection

  • In Receiver sessions, seeking forward in Windows Media Player while playing .MOD, ac3, and mpeg files might cause the video to play without audio.

    [#LC2768]

  • If you play an .avi file with Windows Media Player within an ICA session (or published desktop session) and then start playing another .avi file without stopping the first one, the video frames might not be properly directed to the user device. As a result, the CPU usage of the mmvdhost.exe process can be higher than normal and the video might not render properly on the user device.

    [#LC4260]

Keyboard

  • If you are in a Citrix GoToMeeting running inside a VDA session and are made presenter, your mouse pointer might start to flicker. This occurs when the “Legacy graphics mode” policy setting is disabled for the session.

    [#LC3033]

Logon/Authentication

  • If the Windows Remote Desktop Session Host Configuration policy setting “Always prompt for password upon connection” is enabled, when users log on to VDA 7.x by using the ICA protocol, users receive a prompt to enter their credentials again.

    To enable this fix, set the following registry key:

    HKEY_LOCAL_MACHINE\Software\Citrix\Portica Name: AutoLogon Type: DWORD Data: 0x00000001 (value must be between 1 and 2147483647)

    Note: The Citrix Display Drive can be marked for deletion if there are multiple attempts to run the MSP file. This causes the installation of the hotfix to fail. In addition, the display resolution of the VDA might not work. To allow this to work, restart the VDA and then install the hotfix again.

HDX MediaStream Windows Media Redirection Session/Connection
Keyboard Smart Cards
Printing System Exceptions
Seamless Windows User Experience

Content Redirection

  • Server to client content redirection fails for VDAs other than those running on Windows Server 2008 R2. As a result, when you click a URL in a VDA session, the link opens in a browser running in the session rather than in a local browser.

    [#LC2221]

  • With content redirection enabled for Mailto links, Mailto links that contain commas fail to launch and the following error message appears:

    “Could not perform this operation because the default mail client is not properly installed.”

    The issue does not occur in console or Remote Desktop sessions.

    [#LC3701]

HDX MediaStream Windows Media Redirection

  • In Receiver sessions, seeking forward in Windows Media Player while playing .MOD, ac3, and mpeg files might cause the video to play without audio.

    [#LC2768]

  • If you play an .avi file with Windows Media Player within an ICA session (or published desktop session) and then start playing another .avi file without stopping the first one, the video frames might not be properly directed to the user device. As a result, the CPU usage of the mmvdhost.exe process can be higher than normal and the video might not render properly on the user device.

    [#LC4260]

Keyboard

  • If you are in a Citrix GoToMeeting running inside a VDA session and are made presenter, your mouse pointer might start to flicker. This occurs when the “Legacy graphics mode” policy setting is disabled for the session.

    [#LC3828]

  • Attempts to use the attrib command to change file attributes of files on mapped client drives might fail.

    [#LC3958]

  • Multiple, concurrent attempts to establish a Remote Desktop (RDP) connection to a VDA from separate user devices can cause the VDA to unregister.

    [#LC4014]

  • The Output Session Bandwidth Performance Monitoring counter might report inconsistent values upon recording for a long period of time.

    [#LC4151]

  • When a VDA for Server OS is unregistered or the Citrix Desktop Service is disabled, even domain administrators cannot log on to that VDA through a Remote Desktop (RDP) connection. While that behavior is as designed for non-administrator roles, administrators are expected to be able to log on.

    [#LC4290]

  • If you are logging on to a Version 7.6.300 VDA with explicit credentials (username/password) and User Account Control (UAC) enabled, and then attempt to authenticate to an application running in the session using a smart card, the following error message might appear:

    “An authentication error has occurred. No credentials are available in the security package.”

    [#LC4486]

  • Live scrolling (the synced state of page scrolling and scrollbar motion) does not work in Excel spreadsheets. Version 7.6.300 of the VDA introduced Fix #LC2965, intended to address the issue. However, Fix #LC2965 does not fully resolve the issue in all cases. This Fix, #LC4579, ensures that the issue is corrected even on systems where Fix #LC2965 does not work.

    From the description of #LC2965:

    Live scrolling (the synced state of page scrolling and scrollbar motion) does not work in Excel spreadsheets. The issue occurs because the key and value in registry location HKEY_CURRENT_USER\Control Panel\Desktop\UserPreferencesMask on the VDA are overwritten by the wfshell.exe process each time a user logs on to the VDA. To prevent this, create the following registry key on the VDA and set the value to 1:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix Name: EnableVisualEffect Type: REG_DWORD Value: 1

    [#LC4579]

  • After installing Hotfix ICATS760WX64022 (or its replacements), any new custom registry configuration under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Graphics\ might not be retained when you restart the system.

    [#LC4931]

Session/Connection

  • The Source Network Address displays an incorrect IP address for remote user devices in the server’s Windows Security Log with EVENT ID 4624.

  • With the Client audio redirection or Windows Media Redirection policies disabled, the Volume control (Speaker) icon in the notification area of a published desktop session can display an incorrect audio state.

    [#LC2538]

  • In Citrix Receiver for Android published desktop sessions, attempts to open a Microsoft Outlook calendar invitation can fail with the following error message:

    “Cannot open item”

    The issue occurs with calendar invitation created by other users; invitations created by the same user are not affected.

    [#LC2828]

  • In certain scenarios, the Client Printer Redirection and Citrix Group Policies’ Access Control filters might fail to work while logging on or reconnecting to a disconnected session.

    [#LC3083]

  • In sessions for which you enable Local App Access, the screensaver fails to get activated.

    [#LC3182]

  • The WFICA32.exe process might keep a file locked even after the file was closed by the associated published application. As a result, the file cannot be edited for a while.
