Citrix Director

  • User name searches in Citrix Director might return a list of users listed in Citrix Director unrelated to the search.

    [#LC5415]

  • When using Firefox 41 or later, user names are displayed with a percent-encoded space (i.e. User%20Name).

    [#LC6240] 

Citrix Studio

  • If a user logs onto a physical Remote PC console within 30 seconds after booting up, the “Current User” becomes a dash within Citrix Studio and the user cannot connect to the Remote PC ICA session.

    [#LC5408]

  • The XenDesktop console consumes high amounts of CPU when searching for users.

    [#LC5691]

Controller

  • When attempting to create network resources that contain a pipe symbol (“ ”), connections to the hypervisor might fail with the following error message:

    “Cannot connect to server”

    [#LC4933]

  • If there is any failure in storage repository when copying over to a Machine Creation Services virtual machine, the copy displays as successful despite the copy failing.

    [#LC5430]

  • Machine Creation Services does not recognize the “Allow migration to a Virtual Machine Host with a different processor version” setting during set up.

    [#LC5885]

  • VDAs might get stuck in initializing state after the DDCs are rebooted.

    [#LC6264]

    [#LC6275]

  • When a high number of anonymous users attempt to launch apps/VDAs concurrently, the broker service loses connectivity with the database server.

    [#LC6320]

  • When you set the working directory for a published application, the setting might not be reflected in the published application that is launched in Connection Leasing mode.

    [#LC6397]

    [#LC6616]

Provisioning Services

Console

  • When using a virtual machine to provision virtual machines from a template using a SCVMM cluster, the wizard fails to create the virtual machines after clicking Finish.

    [#LC5871]

  • The XenDesktop Setup Wizard might not perform a full permission check, causing errors in permissions.

    [#LC6190]

Server

  • PVS servers occasionally appear with the status “Server Unreachable” in the Replication Status window.

    [#LC5683]

  • When using a virtual machine to provision virtual machines from a template using a SCVMM cluster, the wizard fails to create the virtual machines after clicking Finish.

    [#LC5871]

  • When the target device’s boot.iso code receives an ARP request that has been sent with a broadcast destination, the target device’s boot.iso code sends an invalid ARP reply.

    [#LC6099]

  • The XenDesktop Setup Wizard might not perform a full permission check, causing errors in permissions.

    [#LC6190]

  • Soapserver might consume more than 13GB of RAM during usage.

    [#LC6199]

  • The bnistack error “[MIoWorkerThread] I/O Stream Socket UNAVAILABLE - not counting retry,” event ID 85, floods the event viewer while the connection to the PVS server is lost.

    [#LC6449]

Session Recording (Player)

  • When you try to play back a recording made with a version of Citrix Receiver that is newer than the version of Session Recording, a message appears, indicating that the file cannot be played back. With this fix, even files recorded with a newer version of Citrix Receiver can be played back.

    [#LC6503]

StoreFront

  • StoreFront does not recognize the correct client IP address even though the proxy server sends the “x-forwarded-for” header in the request.

    [#LC5797]

    [#LC6471]

  • Upgrading StoreFront to version 3.0.2000 from version 2.5 fails with Error 1603. For more information, see Knowledge Center article CTX220411.

    [#LC6816]

Universal Print Server

  • Attempts to print from Microsoft Internet Explorer might fail with the following error message when using the Citrix Universal Print Driver:

    “There was an internal error and Internet Explorer is unable to print this document.”

    [#LC4472]

VDA for Desktop OS

Printing

  • The Citrix Printer Manager Service (Cpsvc.exe) might exit unexpectedly with an access violation error.

    [#LC4665]

  • The XenApp session printers might not be mapped correctly. For example, create two printers on a print server with identical names and add one additional character at the end of any one of the printer name. If you create a session printer policy with these two printers and log on to a VDA, only one printer might be mapped.

    [#LC6385]

Seamless Windows

  • With Excelhook enabled, minimizing and then restoring an Excel workbook can cause the Excel window to lose focus.

    [#LC6637]

Server/Site Administration

  • The link to \Device\MUP on VDA for Desktop OS for 32-bit systems might be missing. As a result, the anti-virus software working as a mini driver might not scan the files on the mapped drive.

    [#LC6041]

Session/Connection

  • Attempts to append data to files on a mapped client drive might fail when the files are opened by users with write-only permissions. The issue occurs when running the PowerShell command “get-process out-file -filepath “\\client\c$\temp\proclist.txt” -Append” for the second time.

    [#LC3895]

  • If another process holds the same lock as picadm.sys, users cannot log off from the session and the session remains in a disconnected state.

    [#LC4415]

  • When transitioning from a user to console session on a remote PC, certain connection properties might not get updated.

    [#LC5139]

  • Client Drive Mapping returns corrupted file path information when an application attempts to enumerate files.

    [#LC5163]

  • When sessions connected through the Cisco WAAS Gateway attempt to transfer files of large size due to buffer overflow on the VDA side, the VDA might exit unexpectedly.

    [#LC5371]

  • If the Client USB device redirection rules policy contains more than 1,000 characters, all USB drives are redirected, even if there is a deny rule for the device.

    [#LC5457]

  • Attempts to open a file might fail when there is an open handle that is overwritten. As a result, the file gets locked by the process.

    [#LC5657]

  • When switching between full-screen and windowed mode in published seamless applications, the applications might become unresponsive if any one of the applications is in the unresponsive state.

    [#LC5774]

  • If you power off or force a remote PC to restart while in a user session, all audio drivers might be disabled when the restart completes.

    [#LC6009]

  • With the Citrix policy “Auto Client Reconnect” set to “Prohibited,” attempts to launch VM Hosted Apps might fail.

    [#LC6103]

  • After upgrading to XenApp and XenDesktop 7.6 Long Term Service Release, copy and paste functionality might not work.

    [#LC6114]

  • When you attempt to download a file by using Citrix Receiver for HTML5, the download window might not be correctly focused. As a result, you cannot select the file that is to be downloaded. As a workaround, minimize the main application window to view the download window from Citrix Receiver for HTML5.

    [#LC6167]

  • This enhancement enables the Citrix Device Redirector service to write event logs related to USB rules and activities.

    [#LC6243]

  • If you power off or force a remote PC to restart while in a user session, all audio drivers might be disabled when the restart completes.

    [#LC6322]

Smart Cards

  • In a configuration where Citrix Receiver for iOS is used to launch desktop sessions to a remote PC, when you log on to StoreFront using an explicit username and password and then attempt to log on locally with a smart card to the physical remote PC, the logon attempt might fail in one of the following two ways:

    • Microsoft Windows recognizes that there is a smart card logon option, but the “Insert a smart card” prompt does not disappear even though the smart card is properly inserted.
    • Microsoft Windows does not list a smart card logon option, even though the smart card reader is attached and the smart card is properly inserted.
       

    [#LC5997]

System Exceptions

  • XenApp servers can experience a fatal exception, displaying a blue screen with stop check code 0x0000000A.

    [#LC5917]

  • VDAs can experience a fatal exception on wdica.sys, displaying a blue screen.

    [#LC5938]

  • Citrix Audio Service (CtxAudioService.exe) might exit unexpectedly.

    [#LC6323]

VDA for Server OS

Printing

  • The Citrix Printer Manager Service (Cpsvc.exe) might exit unexpectedly with an access violation error.

    [#LC4665]

  • The XenApp session printers might not be mapped correctly. For example, create two printers on a print server with identical names and add one additional character at the end of any one of the printer name.

    [#LC6385]

Seamless Windows

  • With Excelhook enabled, minimizing and then restoring an Excel workbook can cause the Excel window to lose focus.

    [#LC6637]

Session/Connection

  • This fix addresses the improper handling of command line parameters from within published desktops as in the following example:

    If you run “C:\Program Files (x86)\Citrix\system32\iexplore.exe” -noframemerging http://www.google.com, Internet Explorer misinterprets the parameter and resolves the URL as http://-noframemerging%20http//www.google.com.

    [#LC3660]

  • Attempts to append data to files on a mapped client drive might fail when the files are opened by users with write-only permissions. The issue occurs when running the PowerShell command “get-process out-file -filepath “\\client\c$\temp\proclist.txt” -Append” for the second time.

    [#LC3895]

  • In XenApp 7.6.300, users with limited visibility to apps in a multi-forest environment might not be able to launch apps.

    [#LC5274]

  • When sessions connected through the Cisco WAAS Gateway attempt to transfer files of large size due to buffer overflow on the VDA side, the VDA might exit unexpectedly.

    [#LC5371]

  • If the Client USB device redirection rules policy contains more than 1,000 characters, all USB drives are redirected, even if there is a deny rule for the device.

    [#LC5457]

  • The VDAs for Server OS might display the VDA’s status as “initializing” rather than “registered.” During that time, no new sessions are brokered for that VDA.

    [#LC5621]

  • Attempts to open a file might fail when there is an open handle that is overwritten. As a result, the file gets locked by the process.

    [#LC5657]

  • When switching between full-screen and windowed mode in published seamless applications, the applications might become unresponsive if any one of the applications is in the unresponsive state.

    [#LC5774]

  • After upgrading to Hotfix Rollup Pack 7, copy and paste functionality might not work.

    [#LC6114]

As a workaround, minimize the main application window to view the download window from Citrix Receiver for HTML5.

    [#LC6167]

  • This enhancement enables the Citrix Device Redirector service to write event logs related to USB rules and activities.

    [#LC6243]

  • The following warning message might appear in the system event log when launching XenApp 7.6 Long Term Service Release Cumulative Update 2 VDA for Server OS or the previous versions:

    “An attempt to connect to the SemsService has failed with error code 0x2.”

    [#LC6311]

  • After upgrading to XenApp 7.6 Long Term Service Release Cumulative Update 1 or Cumulative Update 2, the “/appvve” switch for App-V application might not take effect.

    [#LC6398]
