Fixed issues

The following issues have been fixed since 7.18:

Fixed issues from 1808.1 to 1808.2

Version 1808.2 includes a bug fix for Studio. That fix ensures that you can upgrade Delivery Controllers in multiple batches. For details about upgrading 1808.1 to 1808.2, see CTX237835. [STUD-3339]

Citrix Director

  • Attempts to search for users when assigning them to machines might fail. The selected user is shown as null. [LC8395]

  • When using Citrix Director, Microsoft Internet Explorer 11 might display non-functional scroll bars in the Machine Details section of Filters > Machines > All machines page. [LC9505]

  • The reports generated in CSV format for the logon performance in Citrix Director might use the UTC time zone instead of PST. [LC9854]

  • Some administrators might not be able to access some domains that were added in the web.config domain list. As a result, when you search for a user’s session, an exception occurs and the session details are not displayed. [LC9865]

  • Attempts to set SMPT email alerts in the Email Alert settings page for certain versions of Citrix Director might fail. [LC9869]

Citrix Policy

  • When registry entries are manually pre-populated to session keys under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix, the keys might not be updated upon session start. [LC9977]

Controller

  • Attempts to remove the user assignment from a desktop using Citrix Studio, PowerShell, or Citrix Director by a delegated administrator with a custom role might fail. The issue occurs when custom administrators have permissions to perform the operations on the Delivery Groups but do not have permissions on the Machine Catalogs. [LC8174]

  • The VDAs might intermittently have an invalid power state in Citrix Studio. Studio shows the power state to be OFF even when the VDA is running. [LC8898]

  • You import changes from the principal broker to the Local Host Cache (LHC) database and remove a user or machine from the Active Directory without removing it from Citrix Studio. As a result, errors might occur and the LHC isn’t updated. [LC9054]

  • Deadlocks might occur on XenApp with an application Event ID 2013 during peak connection time. This error message appears: An unexpected exception occurred while the Citrix Broker Service processed an HTTP request. [LC9134]

  • When you upgrade XenApp 7.6 to XenApp 7.15, the permissions for the Licensing folder on the Delivery Controller under C:\Windows\ServiceProfiles\NetworkService\Licensing is overwritten. [LC9445]

  • When you send a reboot command to the target VDA from Citrix Studio, the target VDA might shut down. [LC9479]

  • The Virtual desktop infrastructure (VDI) that is hosted on the ESXi hosts might go into an unknown power state and does not power on automatically. The issue occurs after the virtual machines (VMs) are moved to the ESXi hosts after the ESXi hosts are taken out of maintenance mode. [LC9619]

  • Attempts to create a machine catalog might fail with an exception stating that it cannot create the summary. Additionally, when using the creation catalog wizard and before the exception appears, the drop-down list that is supposed to list the domains is empty. [LC9636]

  • When you add published content to Delivery Groups, the Local Host Cache (LHC) might fail with an Event ID 505. [LC9934]

General

  • In earlier versions, when using Azure Resource Manager on-demand provisioning, all VMs were deleted when powered-off. Now, only pooled VMs are deleted. Persistent (dedicated) VMs are not deleted when powered-off.
  • Multi-stream (with or without multi-port) and session reliability UDP transport information might appear incorrectly as inactive in the HDX monitor or in Director. This might occur when a session is using the multi-stream or multi-port with UDP transport. [HDX-13416]

  • Windows Event Log Error: “Windows is unable to verify the image integrity of the file MfApHook64.dll”. For more information, see CTX226397. [HDX-9063]

Install and upgrade

  • If StoreFront was originally installed using the executable from the installation media, StoreFront does not appear as eligible for upgrade when you use the full-product installer for a later version. As a workaround, upgrade StoreFront using the executable from the installation media. [XAXDINST-43, DNA-47816]

  • XenApp and XenDesktop Site upgrade to version 7.18 fails if the Monitor database is on SQL Server 2008 R2. CTX235820. [DIR-2249]

Universal Print Server

Client

  • The Universal Print Server might cause the Print Spooler service to become unresponsive. [LC9341]

  • The Citrix Print Manager service (cpsvc.exe) and the Print Spooler service might exit unexpectedly. [LC9495]

  • In certain Microsoft Excel files, when you navigate to Excel > Print, and then select any auto-create client printer using the Citrix Universal Printer EMF driver, the characters in the print preview image might appear smaller. [LC9700]

  • The Citrix Print Manager service (cpsvc.exe) might exit unexpectedly. [LC9796]

VDA for Desktop OS

Printing

  • The Citrix Print Manager service (cpsvc.exe) might exit unexpectedly. [LC8804]

  • The default printer might be incorrectly set in a session. The issue occurs when the default printer switches to any other random printer. [LC8999]

Session/Connection

  • Disabling Citrix Hooks might fail to take effect when several executables are added to ExcludedImageNames under the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook. [LC8614]

  • Citrix Director might report Multi-Stream ICA as inactive when using the UDP-based Data Transfer Protocol (UDT). The issue occurs when the HDX WMI provider is not updated to account for EDT or UDT sessions. [LC8960]

  • Inconsistent mouse movement might occur in a multi-monitor environment using H configuration. You start a Microsoft Skype for Business session and start sharing the screen with the other user. The Citrix graphic driver receives an incorrect mouse location from the operating system.

    To enable the fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA

    Name: DisableAppendMouse

    Type: DWORD

    Data: 00000001

    However, when you use the HDX session after setting the registry key, certain features that programmatically set the mouse pointer location might not work as expected. The features are:

    • Mouse Snap To feature.
    • The capability to synchronize mouse location between users with GotoMeeting screen sharing.
    • The capability to synchronize mouse location between users with Skype for Business screen sharing. [LC8976]
  • When you attempt to access a mapped client drive in a session and you don’t respond to a Citrix Workspace Security Warning dialog box, the other user’s session might become unresponsive. [LC9070]

  • The Citrix Audio Service might exit unexpectedly and then restart again. When you reconnect to the same session from the second end point (thin client), the new devices are not mapped correctly to the session. [LC9381]

  • When you disconnect a user session from the first end point and then reconnect to the same session from the second end point (thin client), the client side audio devices might be listed in an incorrect order within the VDA.

    To enable the fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Audio

    Name: CleanMappingWhenDisconnect

    Type: DWORD

    Data: 1 [LC9440]

  • The published application sessions might disconnect and user sessions might not log off correctly from the VDAs. When the issue occurs, you might not be able to reconnect and cannot disconnect from Citrix Studio. To remedy this situation, set the sessions to Hidden using the PowerShell command or restart the VDA. [LC9444]

  • With the Client drive redirection policy disabled, when you start an application for the second time from the user device, the application might take a long time to start. [LC9477]

  • When you attempt to reconnect to an existing session that is active from a different endpoint, this error message appears:

    Connection interrupted; receiver will attempt to reconnect for 5 minutes.

    The issue occurs on Microsoft Windows 7 that has VDA 7.15 installed. [LC9485]

  • A web based application is opened using Microsoft Internet Explorer or Mozilla Firefox browser. When you open certain tabs in the application, the entire desktop might become unresponsive. [LC9508]

  • The Server Total instance performance counter might be missing from the ICA Session counters. [LC9537]

  • File type association with Local App Access enabled might not work when the files are on the distributed file system (DFS) drive. [LC9538]

  • The Event ID 31 Start Listening for Connections might not be passed to the Event Viewer. [LC9556]

  • After upgrading XenApp and XenDesktop from version 7.6 to version 7.15 LTSR Cumulative Update 1, certain services might stop or exit unexpectedly, or become unresponsive intermittently during logon. [LC9679]

  • After you upgrade the VDA that is running on XenApp and XenDesktop to version 7.17, the custom virtual channels might fail to initialize the devices and applications. [LC9916]

  • The Kana language input key on the Japanese Input Method Editor (IME) might be automatically enabled when you log on to a VDA. [LC9932]

System Exceptions

  • Servers might experience a fatal exception on picadm.sys and display a blue screen with bug check code 0x22 (FILE_SYSTEM). [LC7726]

  • Servers might experience a fatal exception on picadm.sys and display a blue screen with bug check code 0x000000D1(DRIVER_IRQL_NOT_LESS_OR_EQUAL). [LC8830]

  • The VDA for Server OS might experience a fatal exception on wdica.sys and display a blue screen. [LC9695]

  • The wfshell.exe process might exit unexpectedly when attempting to start a published application. The issue occurs when the bidirectional content redirection policy is enabled, while no URLs are provided. [LC9705]

User Experience

  • When you change the resolution of the screen and reconnect to the published application from a VDA for Desktop OS, the application window might be truncated. [LC9947]

VDA for Server OS

Printing

  • The Citrix Print Manager service (cpsvc.exe) might exit unexpectedly. [LC8804]

  • The default printer might be incorrectly set in a session. The issue occurs when the default printer switches to any other random printer. [LC8999]

  • File type association with Local App Access enabled might not work when the files are on the distributed file system (DFS) drive. [LC9538]

  • In multiple domains or multi-forest environments, you might not be able to start the second application when the local groups are configured for limited visibility. [LC9665]

  • After upgrading XenApp and XenDesktop from version 7.6 to version 7.15 LTSR Cumulative Update 1, certain services might stop or exit unexpectedly, or become unresponsive intermittently during logon. [LC9679]

  • You plug in a USB storage device during session logon and redirect with generic mode. The drive might still exist after you unplug the USB device. [LC9783]

  • After you upgrade the VDA that is running on XenApp and XenDesktop to version 7.17, the custom virtual channels might fail to initialize the devices and applications. [LC9916]

  • The Kana language input key on the Japanese Input Method Editor (IME) might be automatically enabled when you log on to a VDA. [LC9932]

  • When you resize the window or right-click to bring up the context menu of a published application that is running on the VDA, the performance of the application might be slow. [LD0174]

Smart Cards

  • You set the registry value DisableLogonUISuppression to 0 under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Citrix Virtual Desktop Agent. When you start a published application, the VDA might require you to type the smart card pin. The message Please wait for the local session manager appears in Citrix Receiver for Windows and eventually times out because the DisableLogonUISuppression value 0 suppresses the LogonUI PIN prompt. As a result, the PIN prompt never appears.

    To enable the fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Citrix Virtual Desktop Agent

    Name: DisableLogonUISuppressionForSmartCardPublishedApps

    Type: DWORD

    Data: 1 [LC9059]

System Exceptions

  • Servers might experience a fatal exception on picadm.sys and display a blue screen with bug check code 0x22 (FILE_SYSTEM). [LC7726]

  • The VDA for Server OS might experience a fatal exception on wdica.sys and display a blue screen. [LC9695]

  • The wfshell.exe process might exit unexpectedly when attempting to start a published application. The issue occurs when the bidirectional content redirection policy is enabled, while no URLs are provided. [LC9705]

  • When you start an application, the wfshell.exe process might exit unexpectedly. The issue occurs because of the faulting module, icaendpoint.dll. [LC9737]

User Interface

  • A legal notice appears at the start of the logon screen in a user session. With Local App Access enabled, when you click Ok on the logon screen to continue, the screen might show the legal notice for several seconds before proceeding with the logon. [LC9408]

Virtual Desktop Components - Other

  • Citrix Director might report Multi-Stream ICA as inactive when using the UDP-based Data Transfer Protocol (UDT). The issue occurs when the HDX WMI provider is not updated to account for EDT or UDT sessions. [LC8960]

  • Started applications might not appear in the Activity Manager in Citrix Director in a double hop scenario. [LC8985]
