Note

Known issues list is being updated and accordingly release notes will also be updated.

Installation and Upgrade Issues

# Subject
15006 Controller installation with SQL 2008 is not supported.
15213 On upgrading to v3.3-GA (12803), incorrrect RDP port is configured in desktop pool configuration. Incorrect port - 3889; Correct port - 3389.
Impact: The bug can cause connection failures to shared hosted desktops post upgrade.
14599 After upgrading to 3.3 GA, authentication server is not reachable.
Impact: User login failures. HyWorks deployments having AD group as super-administrator, admin login will also fail and whole system may become unaccessible.
Workaround:
Change Active Directory option value to 2 or 3 in database - Table Name: ClusterServerSettingsDbo, Field Name: ADGroupAccess Type, Set Value: 2 or 3 Recommended
Repair HyWorks Controller after upgrade and set super-administrator as local HyWorks user. Login into Management console with new super admin, update Active directory options value to 3 from 6 in System - Advanced Config and save or update authentication server configurations to have base DN and other new mandatory fields.

Controller Known Issues

# Subject
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 will require node to be destroyed before removal as on service start the node may again get added
13889 Internal configuration is displayed in the error message when user is not able to connect to the AD server.
13767 When user select user setting from connection profile and from Endpoint select single monitor. Still user able to use multi monitor.
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 which makes it difficult for Administrator to understand the issue
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 behaviour 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 associated objects from database and then try 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 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 deallocation and because power-off is equivalent to stop with deallocation, 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: Requires Skip attribute verification to be enabled
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 **Controller (it can be default 38866 or non-default port)
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 other reasons such as licensing or SQL connection issues
11334 Current weighted round robin does not work in true round robin method 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.
11324 Role using SQL must be done every time Session manager node is added in the configuration
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 doesn't 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: Need to clean-up everything from database as per table references mentioned in logs
5729 In some rare 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 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
