  • When logging off, Profile Management occasionally locks files/folders on the server, causing applications to fail to launch. Locally cached profiles also do not get deleted. [LC5266]

  • Profile Management occasionally locks files in user profiles. When this happens, users receive a temporary profile while trying to reconnect until the lock on their profile is released. [LC5278]

  • Locally cached profiles might not delete when users log off. [LC5470]

  • When the license server is offline, files using the user redirection folder on the server are lost. [LC5595]

  • Users’ files are lost when the license trial period ends without renewal. [LC5775]

  • Profile Management might incorrectly raise a “NetworkDetection” flag indicating that the network might be lost. This fix introduces an extra check to ensure that the network is not available instead of temporarily being unavailable. [LC5943]

  • Occasionally, the user logon screen becomes unresponsive on Windows Server 2012 R2. [LC6149]

  • Attempts to migrate roaming profiles into Profile Management might fail. The issue occurs when an incorrect version number is added to the profile. [LC6150]

  • The application icons might appear as grayed out when you attempt to copy the icons from the Profile Management user profile store through a WAN connection. [LC6152]

  • File type associations might fail to roam in Profile Management enabled sessions running on Microsoft Windows 10 and Windows Server 2016. [LC6736]

  • With the “Delete local cache at logoff” policy enabled on Microsoft Windows 10 or Windows Server 2016, the NTUSER.DAT file might fail to be deleted at logoff, causing another local profile to be created at the next logon. [LC6765]

  • When using Profile Management on Microsoft Windows Server 2016 and usrclass.dat is included, the Start menu might not work. [LC6914]

  • When you attempt to open files in a profile with Profile Streaming enabled, the file might appear empty after you log on. [LC6996]

  • Profile Management can cause a black screen to appear when you attempt to launch a Microsoft Windows 10 session. With this fix, you must configure the policy “Directories to synchronize” and add the folder “*AppData\Local\Microsoft\Windows\Caches*.” [LC7596]

Provisioning Services

Console Issues

  • With this fix, the “Schedule the next vDisk update to occur on” option and “Apply vDisk updates as soon as they are directed by the server” option are no longer available for Provisioning Services. [LA4166]

  • Attempts to create virtual machines through the XenDesktop setup wizard might fail in a non-English Microsoft System Center Virtual Machine Manager (SCVMM) environment. [LC5451]

  • Attempts to create an ISO with the New-BootDeviceManager PowerShell script can fail and the following error message appears: “ISOFileName must be called with the name of the new ISO file to create.” [LC5559]

  • When using clustered volume storage, the Streamed VM Setup wizard does not honor the volume selection and can create target devices on random volumes. [LC5890]

  • Attempts to close the Provisioning Services Console after running the XenDesktop Setup wizard or the Streamed VM Setup wizard can result in an exception. [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"
    
     ]
    
     }
     <!--NeedCopy-->
    

    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. [LC6249]

  • After configuring the Provisioning Services Console, the label names might be missing in the target device properties. [LC6864]

Server Issues

  • In VMware ESX deployments, the XenDesktop Setup wizard can throw an exception, preventing users from setting up templates and machines properly. [LA2499]

  • Two PVS servers might not be able to see the replication status of a vDisk on the opposite server, but each server shows the status of its own vDisks properly. [LC4317]

  • The Citrix PXE service might ignore the entries in the BOOTPTAB file. [#LC4600]

  • When using a BDM partition, target devices running on VMware do not attempt to log on to all servers in the list if the top-most server is unreachable. [LC4736]

  • Attempts to create virtual machines through the XenDesktop setup wizard might fail in a non-English Microsoft System Center Virtual Machine Manager (SCVMM) environment. [LC5451]

  • If not all partitions on a hard drive are being cloned, the final partitions that are being cloned might fail. [LC5452]

  • When running replication status for two PVS servers from the PVS console, the status for both servers is shown as incomplete. [LC5700]

  • When using clustered volume storage, the Streamed VM Setup wizard does not honor the volume selection and can create target devices on random volumes. [LC5890]

  • 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]

     \]
    
     }
     <!--NeedCopy-->
    

    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. [LC6249]

Target Issues

  • The auto update feature of the Provisioning Services Target device generates the following application error message (Event ID: 0) in the target’s Event Viewer if the update is not available. “No update server found. Stopping client service.” [LC0450]

  • The target device software does not recognize the AppDisk drive and uses the AppDisk drive for write cache, which can cause conflicts. [LC5409]

  • When you configure a vDisk to use “Write Cache on RAM” and set the RAM cache size to 4,096 MB or 4,097 MB, booting from a Hyper-V GEN-2 virtual machine can cause target devices to experience a fatal exception, displaying a blue screen. [LC6707]

StoreFront

  • If the Administrator changes the group policy setting, MaxPasswordAge, the StoreFront default domain service does not reload the new value. In StoreFront, the user may be shown the incorrect “number of days until password expiry”.

    Note: This issue is fixed, however it can take up to an hour for the new value to load. [DNA-41380]

  • With StoreFront 3.5 installed, the folder color in the categories view might no longer use the custom color defined in the StoreFront management console. It reverts to the default color. [LC5001]

  • Enabling Federated Authentication Service on StoreFront might cause logon errors. [LC5708]

  • Even with Citrix Receiver for HTML5 enabled in Citrix StoreFront, the StoreFront console might display “Not Used” instead of displaying the HTML version. [LC6626]

  • When you select a configured Site during the setup of XenDesktop, a default store might be created in StoreFront that uses the default Authentication Service. If you remove this store, users of Citrix Receiver for Windows cannot add any other stores and the following error message might appear:

    “A protocol error occurred while communicating with the Authentication Service.” [LC6664]

  • If you configure Self-Service Password Reset (SSPR) for a specific store from the StoreFront console, the configuration applies to all stores, not just to the specific store you selected. [LC6987]

  • Attempts to reconnect to disconnected sessions might fail within a multi-Site aggregation deployment. As a result, you might receive a second instance of the same resource. [LC7453]

  • When any of the sources of an aggregated application are 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]
