HyWorks Controller Known Issues

  • Last Updated Date: 22-Sep-2022
  • Release: HyWorks v3.4

Note

The Known issues list is updated with every release. This is the current list of known issues.

# Subject
26215 With deployment settings being kept as default, all the cloned VMs are getting cloned on a single host on which gold master is running, even when the gold master is in cluster.
Workaround: Make sure to specify deployment settings to be deployed at the cluster level.
26042 All the cloned VMs are created on the same storage container as the gold master and not on the specified storage container at the time of cloning with Nutanix.
25836 An incomplete and confusing error is logged in HyWork, when user's attempt to change password fails because of complexity requirements.
25659 Even though User initiates the Power operations on VMs, the log is getting generated again system user in the Controller logs.
25346 Controller continues to show old platform for logged in user and does not refreshes the platform information.
24997 Same users from different authentication server can be added, if configurations are changed in auth-domain, e.g. auth-domain configuration is changed from built-in/built-in to LDAP/built-in or vice versa.
Impact: The duplicate entries may confuse administrator and also may result in login or authorization failures sometimes.
Recommendations: The organization configurations should be planned well so that it does not require change. Even if it needed change, clean-up of HyWorks should be done to remove all users from previous auth-domain configurations.
24885
22968
Oracle Data Disk and OS Disk snapshot is not getting deleted in set time and in case of recompose the old snapshot may be used for provisioning causing the changes done on Gold master to be ignored.
24678 Controller creates an error log if user refreshes the app list on client side and previously some virtual apps in remote app mode are opened and then closed. Error log: No App session found to reconnect for User 'Username'.
24527 In some rare cases VM deletion was failed with error "The Object context instance has been disposed and can no longer be used for operations that require a connection", while deleting the desktop pool.
Workaround: Manually remove the VM from HyWorks and respective provider.
24380 Password change may fail with exception, if port 636 is not reachable from HyWorks Controller or appropriate certificate configurations are not done on active directory server and option 6 is used for active directory connection.
Exception: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host
24373 HyWorks Controller does not log VM image creation on AWS. There is no impact of this but eventually can create some confusion as VM image deletion logs are generated after cloning is completed.
24017 Power operations initiated by client may fail with a non-user friendly exception in multi-node cluster deployment of HyWorks Controller and broker nodes are unable to reach to Microsoft Azure.
Exception: Unable to perform 'Power-on' operation on the desktop [VM-name] for the user 'Username'. More info: Invalid Credentials.
23805 Provisioned SHDs published as physical PCs are not responding without showing error displayed.
The issue is because, all the physical VMs added with same IP address are going to have duplicate IP and in that case controller does not show agent status.
23491 HyWorks may leave some residual data of organization during deletion and may cause complete management console to be inaccessible.
Workaround: Remove the details of deleted organization from database.
23463 Controller uses VM-name to unregister from domain for deployed VMs instead of computer name (Fails in all cases where computer name is different than VM name).
Workaround: Administrators should use same name for fields VM name (Deployment screen) and Computer name (On Customization screen).
23376 Cloning fails when Gold master is created from vSphere server instead of vCenter.
Workaround: Create Gold master VM from vCenter Server wizard.
22148 Sometimes exception on HyWorks Controller is logged after service service restart for stopping scheduler service.
Exception: Cannot stop EDCSchedulerService service on computer '.'. -> System.ComponentModel.Win32Exception: The pipe has been ended.
21958 Client entry is not getting updated after updating DN for a user and so multiple client entries are created.
21829 By default for fresh controller installation, with active directory option# 6 for user authentication and authorization, built-in groups and nested groups do not work in HyWorks Controller.
If required it can be changed from HyWorks Controller > Advance Settings.
21731 Controller does not create synchronization logs for a very long period of time when the secondary server with a very large number of records has been added to a controller.
21724 SQL transactions fails on the Controller, when too many devices (100K) are registered.
21287 With small timeouts on HyWorks (< 5 minutes), sessions taken from HyLite may get logged out abruptly though user is working.
This happens because the default sync time between HyLite and Controller is 5 minutes. It is recommended to have timeouts more than 10 minutes, when delivering with HyLite.
21044 Controller access via VIP does not work, if network adapter used for VIP configuration is having space in it.
Workaround: Change network adapter name to have no spaces and same name on both controllers.
20866 Controller sets display name same as username while importing users from LDAP and does not use the actual display name configured on LDAP.
20800 On initiating sync session info action on inactive session provider, controller displays a success status but does not perform any sync operation.
The behavior is also different, when performing the same operation on session team with inactive session provider where appropriate logs will be created.
20733 Active directory server fails to be added into HyWorks, having following policy enabled:
Policy: "Domain controller: LDAP server signing requirements" enabled and configured as "Require signing"
Exception: Additional non-parsable characters are at the end of the string
20616 With too many records for synchronization (more than 100000), cluster configuration fails and primary server may go into fault mode.
Workaround: Create secondary server with backup of primary database and then add to HA, avoiding too much synchronization.
20296 Adding a deployed shared hosted desktop pool creates a team with same name as desktop pool name but updating the desktop pool name does not update the team name.
20202 Network Settings details are not integrated in CSV export from session teams page.
20129
18966
Controller does not support DVM Tools - Lite upgrade.
Provisioned SHDs shown in VMs page can be incorrectly upgraded to DVM tools instead of Lite, because of above issue and may cause functional issues.
20124 Reason of service not responding for Linux session host server is shown as "Feature not available" and may cause little confusion.
20119 If a Windows session host server configured in HyWorks is powered-off, it can create a confusing log.
Log: The Session Provider 'provider name' is not reachable. More Info :Unable to connect to the Session Provider hosted at 'Not Available'. Reason: Unable to parse URI 'http://Not Available, Reason: Invalid URI: The hostname could not be parsed..
20009 In some cases, HyWorks may log an error while deleting desktop pool, though related objects are deleted successfully.
Error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded.
19984 Configuring static IP address on Gold master may result in duplicate IPs in the network post provisioning.
19983 Controller may fail to delete a device having associated session and attempts to register into another organization. Ideally Controller should delete the associated sessions also.
19868 The shutdown operation on Linux VMs is kept on hold, if someone has logged-in to the VM from hypervisor console session.
19664 Controller lists all attached VIPs, while trying to change primary IP for the VM. Ideally VIPs should not be listed as they are not always attached to virtual machines.
19560 Saving a session team with a very long range of VIP may get stuck and cause high resource (memory/CPU) utilization by controller service.
Workaround: Create some small network range and configure it on team.
19091 Controller by default uses the primary or first IP on the network interface added on Azure VM, though VM has multiple IP addresses configured on network interface. Option to choose primary IP will not work for Azure provider VMs.
19038 If a permanent VIP is having issue, the user session will be rejected unless the issue is solved or a new VIP is assigned.
18830 Controller may intermittently show error "Error while getting device software information for EDCA00MAC000", causing some confusion.
18507 With too many users connecting a time (more than 10 users per second)
18327 Controller transactions with SQL may get failed with timeout exception if database diagram is created.
Usually database diagram is created when user clicks on it and it checks with user to create it.
18078 In case of domain controllers are deployed in child-parent configuration and HyWorks is configured with child domain, it does not fetch groups or OUs from parent domain controller.
18015 Changes to management are not forbidden from session nodes, so if any deployment is having management console installed on session nodes, changes can be done from session nodes as well.
18006 Controller displays a confusing error invalid username and password, when SAM Account Name is to be used for logon but truncate is off and user is using username@domain-name or domain-name/username to sign-in.
14404 If special characters %/\" are included in Gold Image (Source VM) name or snapshot name for vCenter, snapshot of replica is getting created every time after increasing the count of VM for Persistent pool of type linked clone
Avoid using special characters in Gold Image (Source VM) name or snapshot name.
14376 Incorrect error message is displayed in Test connection of AD, when configured admin account is locked
14375 If the user has changed password, Auth domain (AD/Built-in) and synchronization as Do not create/ Manual, connection to dedicated desktop fails.
14305 [HA] Removal of controller from HA setup leave Tracking Table in DB.
14256 With CredSSP enabled, sessions from Linux based endpoints will fail because of protocol negotiation.
Workaround: Create a separate connection profile for Linux based endpoints.
14083 Deleting a node from HyWorks Controller active-active setup requires node to be destroyed before removal as on service start the node may again get added.
13923 Controller will fail to authenticate users, who are member of "CNF" group in AD.
Exception: XML parsing: line 1, character 1744, illegal xml character.
How is CNF group created: If an object is created on one domain controller and an object with the same name is created in the same container on another domain controller before replication occurs, it creates an object name conflict. Active Directory automatically changes the relative distinguished name of the object with the earlier timestamp to a unique name.

13889 Internal configuration is displayed in the error message when user is not able to connect to the AD server.
13767 Even when the single Monitor usage is set in the Endpoint, user is able to use multiple monitors.
13667 User's are not notified about the destruction of desktops they are working on.
13256 Enable DVM reset option is not working for SHD desktop pool due to which snapshot is not created.
13189 User friendly logs are not displayed when controller tries to get the weight of SHD servers which is not in a reachable state.
12972 While performing power operation, internal configuration is displayed in the Controller logs. Due to this, Administrator may not understand which desktop is affected.
12971 Connect desktop logs are not user friendly.
12942 It is not possible to delete vCenter server with 6000 or more VMs.
12871 AD User is not able to log in to client with 256 character length password.
12792 Unpredictable behavior when Round robin load balancing is used with multiple teams.
12564 With UPN as logon attribute, following special characters do not work in username “|\@”`
12561 User, Group or OU with pipe | character is not supported in HyWorks so user logon fails
12547 Fetching OU in entitlements fails if search string includes bracket ( ). Workaround: Search without bracket
12539 If backslash() is included in username, user might have login issues while logging from client using UPN.
12518 Secondary controller hangs and is not able to sync if primary controller is having a large amount of data (1L rows).
12517 Authorization with built-in and nested AD group does not work when Group retrieval type is set to 6 Workaround: Add entitlement using groups created manually and specific groups only.
12458 Desktop provisioning continues even when enough resources are not available on desktop provider (VMware, Nutanix, Azure, Hyper-V).
12439 Unable to delete the AD when reservations created by AD user exists in RMS Workaround: Delete all the associated objects from database before removing AD.
12436 User friendly errors are not logged when cloning fails and Administrator has to check respective Hypervisor or cloud logs.
12434 In many cases, test connection failure may not give detailed exception and thus more analysis of controller/ AD server is required.
12432 Controller fails to fetch OU details if domain name provided in AD configuration is not same as NetBIOS name.
12406 Desktop status is shown incorrectly as Not synced instead of Missing if configured DVM is deleted from the session provider.
12403 Misleading status of desktop VM, when user initiates shutdown internally. HyWorks does not support stop with de-allocation and because power-off is equivalent to stop with de-allocation, incorrect status is displayed.
12402 Status of Desktop agent is Not Responding, when multiple VMs with different IP addresses are present in HyWorks with same IP address.
12399 HyWorks Controller Logs : Username and APPS name is not appearing in Log Details.
12384 Controller Installation on WVD: 1. IIS installation externally (Class not registered) 2. MSMQ installation externally ([RMSBackgroundWorker] while monitoring import events).
12371 [Azure] Log message incorrectly states that recreation of Desktop VM is supported when it is possible to recreate Desktop VMs
12341 Large deployments with 10000 users might fail due to application connection issues.
13334 In User Details, primary AD server details are displayed even when user is authorized from the secondary server.
12328 AD server configuration fails with error "The specified forest does not exist or cannot be contacted." Workaround: Enable Skip attribute verification.
12319 Skip Login Attribute Verification settings is not retained after updating AD server Workaround: Check this configuration every time active directory configuration is updated.
12317 Session nodes logs provide misleading information when management nodes get switched ON.
12187 Incorrect error message shown to user when user account has expired in AD and Group retrieval type is set as '3'
11950 When the Controllers in HA cluster are configured with different ports than information about different ports is not visible on client
Workaround: Use same port for both the Controllers.
11884 Controller installation on other than default port does not get updated in management console configuration. Workaround: Update Management console configuration file to point to modified ports.
11784 [Azure] FQDN of cloned VM not reflecting on desktop VM page.
11780 On user session reconnection (re-login by user), controller may give reconnect of disconnected RDS session with no app running in some rare case, where user has closed the remote app before the disconnection.
11635 Session host server resource data does not get updated in real time and thus with adaptive load balancing server score will be updated after 30 second duration and may cause session from same server for some time until score gets updated.
- Deleting a node from HyWorks Controller active-active setup will require node to be destroyed before removal as on service start the node may again get added.
11349 External load balancers must use HyWorks health probe service to detect node health, using port reachability may cause failure in detection of node down due to reasons such as licensing or SQL connection issues.
11334 Current weighted round robin does not work in the expected manner and may end up giving more session than expected.
11330 HyWorks uses Least connection load mechanism to serve the session when multiple sessions are requested at the same time. Due to this it might happen that multiple sessions may get served by the same server.
11263 Database gets deleted incorrectly if it is pointed at the time of installing new node and the installation fails. Workaround: Installation should be done using dummy database and node should be configured in the cluster post installation.
- Database gets deleted after session node is uninstalled. This happens because by default database is removed after uninstalling node. Workaround: Uncheck Post installation database removal permission.
10992 When LDAP server is configured over SSL, it takes time to authorize/authenticate as Controller tries to resolve additional hosts. Workaround: Add appropriate host entry to reduce host resolution interval.
10575 Sometimes power off operation does not work with Nutanix dedicated session provider.
10327 Nutanix may keep old IP cache for some time and thus may result giving two IPs to HyWorks Controller causing issues.
Workaround: Configure controller to use appropriate IP filtering.
9569 HyWorks may not fail to authorize from configuration using AD for authentication and built-in for authorization but using UPN as logon attribute.
9519 HyWorks sends logs to Accops Reporting Server or Syslog only once. Due to this, if it fails to send logs, these logs are lost and reports does not show data points of that duration.
9493 HyWorks database restore fails if the parameters - Username, password, SQL server version, location; configured in the new SQL server and the one which is to be restored are same.
8555 HyWorks may not work correctly with proxy authentication server e.g. Accops directory server.
8439 Shadow sessions are created using the connection profile of the actual user session. Due to this, it might happen that Shadow session may not have features it actually requires. E.g. In user session, connection bar is disabled but in shadow session it will be needed.
- Base DN and User DN is mandatory for configuring directory searcher option as LDAP searcher from advance config.
- As Controller requires FQDN to communicate with AD over SSL, if Controller needs to point to a specific AD instance, its host entries must be created otherwise Controller will continue to use first resolved AD. With multiple session manager nodes, this is required for all the nodes.
- DVM Power Policies in DVM Pool may conflict with Auto-login (Auto-login will keep the machine powered-on whereas power policy may try to power-off the DVMs). Administrators are required to keep power policies as default or disabled in DVM pools if intending to have auto login on registered devices.
7478 Power off, Reset or suspend events are not known to DVM agent and thus controller will not be notified immediately. Power status will be updated as per timeouts in HyWorks Controller.
7466 DVM Push will not work with SQL installed in Windows authentication mode only.
7082 Virtual IP for HA script does not support Ethernet name with space.
6380 Sometimes error log 'Object reference not set to an instance of an object' are generated, while restarting session host server.
6330 Logs are not generated, when desktop is not assigned to users if they are in maintenance mode on desktop pool.
6114 HyWorks Controller requires restart to refresh time zone details.
6101 Unable to delete organization though all visible objects in organizations are deleted.
Workaround: Before deleting organization, remove all the table references mentioned in logs.
5729 In some cases, HyWorks Controller installer is unable to detect correct OS type & previous installation of controller.
5698 Sometimes, select checkpoint in desktop pool wizard does not work in single click and may require reselection.
5681 With large deployments Hyper-V connector may stop responding and communication issues may occur due to timeouts or SSL errors.
5375 No desktop VM's are seen in Desktop VM tab of management console with zoomed in browser settings.
5279 Unable to authorize using built-in group Domain Users, when controller is not in same domain as configured AD (Both as authentication and authorization server).
5278 In Desktop pools - OU with special character is shown with garbage characters and after saving changes to "on" string
5273 HyWorks Controller does not support provisioning using templates with vCenter Server dedicated session provider.
5171 Pervious entitlements with authorization AD can login into client when authorization is changed to built-in when removal of entitlements.
5105 Some threads continue to connect to dedicated session provider though it’s made inactive.
5083 Updated AD group membership change is not getting fetched and thus failing to assign the desktops/apps runtime.
Workaround: Use advanced settings to use alternate methods of fetching groups.
5026 Desktop pools and reservations become accessible once associated client groups are deleted.
4840 Gold master concurrent access is not restricted, and hence multiple users can access desktops which supports multi-user sessions e.g. Linux desktops.

Controller Management Console Known Issues

# Subject
26323 A misleading error "There is no authentication server configured" is shown while searching for a user with dot and auth-domain configuration is using built-in users.
26295 Login with HySecure link becomes visible though not enabled while trying to login with invalid credentials into management Console.
25963 Option to enable DVM Reset is disabled, while adding new persistent desktop pool with dynamic provisioning.
The issue is affecting all connectors: Nutanix, vCenter, SCVMM etc.

24866 A misleading error "One or more error occurred" is shown when administrator tries to add Oracle as connector in HyWorks with any of the incorrect details.
24804 Management Console fails to open, where its installed on Windows 2012R2 or lower with internal error 500.19.
Workaround: Delete the following flag from web.config:


22523 HyLite does not use the portal settings of HyWorks - Organization and thus all the customization have to be run via HySecure management console or HyLite configurations.
21121 HyWorks management console UI gets distorted while searching the groups or OUs with special characters e.g. pipe "|".
20961 Saving a session team after assigning more than 2.5K applications, management console becomes inaccessible.
20959 Server page in Management console displays list of configured servers without IP address, if the ethernet card, holding the primary IP address used to configured server on HyWorks is deleted from the provider.
20051 Incorrect VIP is shown in dialog box while removing the Permanent VIP assignment for user from User details page.
18827 To play session recording using HyWorks management console, either appropriate certificate must be configured on the SRMS server or exception should be added on user's machine.
To add exception: Get the complete recording URL by inspecting recording icon, open it in browser, when warning is displayed, accept it to proceed. Now the media or recordings can be played.
18524 Files deleted from SRMS server by administrator, will not be removed from Management console list and will fail to play.
18502 Deleting a recording profile assigned to connection profile fails but displays a success message and thus causes a confusion and also functional issues.
14424 It is not possible to exit the Desktop pool wizard if the Administrator has specified VM name prefix with unsupported chars and later corrected it
14405 Fetching Gold Master at the time of recompose results in exception if Gold Master name includes special characters.

14384 Change mode reflects with quite delayed response on UI and requires manual refresh.
14371 DVM Reset option is getting enabled and editable on selecting recompose for a non-persistent pool though no function impact even when unchecked.
14368 on Re-editing the Dedicated Desktop pool, section shown below Assign Desktop "on connect" is not getting displayed.
14365 On enabling Unassign User on VDI Logoff during Desktop pool creation, it is showing warning that Hybrid mode is not enabled even when the Hybrid mode is enabled.
14324 Adaptive load balancing type option should not visible for Linux session team, as monitoring service is not implemented in Linux SHD
14314 [Licensing] License is getting allocated to child Organization after 100% utilization in parent organization if License are all shared.
14313 [Licensing] Unable update license if all the license is used (Reserved +Shared) with 100% utilized license to (all Reserved with unlimited check).

14228 At times when user launchs app, SHD session is launched instead application.
14079 'Get icon automatically' option for application getting failed for Windows 2k19 server.
14060 Desktop removal on editing desktop pool is not working for Managed SHD pools.
13808 [3.2sp2+hf5/3.3 ]: Scrolling issue on left side tabs when using laptop touch pad.
13510 Select source VM test call fails in case of multiple IPs.
13235 It is possible to decrease the configured count of Maximum capacity than already deployed desktop count for SHD cloning pool. Ideally it should not possible to decrease.
13207 Controller is truncating the LDAP user, whose having leading and trailing space in it hence unable to login into Linux SHD.
12977 Manual assignment does not work when user select Group in Desktop Pool.
12874 Password field value visible, inspect and then by replacing password with text.
11861 Some labels or column values are different than their actual value in database and thus search on those columns may not work as expected.
7764 Dashboard - License section graph gets refreshed with abrupt flickering.
7439 Dedicated providers are added when they are unreachable with active flag.
7431 HyWorks management console session persists so user is able to access Console even without password by using previous and next button of the browser. .
6712 'Limit Single Instance per user' should be enabled and non-editable for Linux application.
6614 Existing Custom URL's doesn't have edit option.

3142 Download logs fails with Management Console in Japanese with error-61 (Japanese OS).

Upgrade Service Known Issues

# Subject
5027 High memory consumption by Upgrade Service with too many upgrades initiated for DVM tools.
