Horizon Help Desk Tool

The Horizon Help Desk Tool provides a troubleshooting interface for the help desk that is installed by default on Connection Servers. To access the Horizon Help Desk Tool, navigate to https://<CS_FQDN>/helpdesk, where <CS_FQDN> is the fully qualified domain name of the Connection Server, or click the Help Desk button in the Horizon Administrator console.

The Help Desk Tool was introduced in Horizon 7.2 and has been greatly expanded upon in the Horizon 7.3 release.

Help Desktop Tool features with Horizon 7.2:

  • Virtual machine metrics
  • Remote assistance
  • Session control (restart, logoff, reset, and disconnect)
  • Sending messages

Additional features with Horizon 7.3:

  • Display application process resources with reset control
  • Role-based access control for help desk staff
  • Activity logging for help desk staff
  • Granular login time metrics
  • Display Horizon Client information

User Session Details

The user session details appear on the Details tab when you click a user name in the Computer Name option on the Sessions tab. You can view details for Horizon Client, the VDI desktop or RDSH-published desktop, CPU and memory stats, and many other details.

  • Client version
  • Unified Access Gateway name and IP address
  • Logon breakdown (client to broker):
    • Brokering
    • GPO load
    • Profile load
    • Interactive
    • Authentication

Blast Extreme Metrics

Blast extreme metrics that have been added include estimated bandwidth (uplink), packet loss, and transmitted and received traffic counters for imaging, audio, and CDR.

Note the following behavior:

  • The text-based counters do not auto-update in the dashboard. Close and reopen the session details to refresh the information.
  • The counters for transmitted and received traffic counters are accumulative from the point the session is queried/polled.

Blast Extreme Metrics for a Windows 10 Virtual Desktop Session

Display and Reset Application Processes and Resources

This new feature provides help desk staff with a granular option to resolve problematic processes without affecting the entire user session, similar to Windows Task Manager. The session processes appear on the Processes tab when you click a user name in the Computer Name option on the Sessions tab. For each user session, you can view additional details about CPU- and memory-related processes to diagnose issues.

Role-based Access Control and Custom Roles

You can assign the following predefined administrator roles to Horizon Help Desk Tool administrators to delegate the troubleshooting tasks between administrator users:

  • Help Desk Administrator
  • Help Desk Administrator (Read Only)

You can also create custom roles by assigning the Manage Help Desk (Read Only) privilege along with any other privileges based on the Help Desk Administrator role or Help Desk Administrator (Read Only) role.

Members of the Help Desk Administrators (Read Only) role do not have access to following controls; in fact, functions such as Log Off and Reset are not presented in the user interface.

Watch this brief demonstration video of the Horizon Help Desk Tool to see it in action:

Horizon Virtualization Pack for Skype for Business

You can now make optimized audio and video calls with Skype for Business inside a virtual desktop without negatively affecting the virtual infrastructure and overloading the network.

All media processing takes place on the client machine instead of in the virtual desktop during a Skype audio and video call.

New support with many expanded features for the Horizon Virtualization Pack for Skype for Business can be found in Horizon 7.3 and Client 4.6.

New Features

Horizon Virtualization Pack for Skype for Business offers the following supported features:

System Requirements

The following table outlines the system requirements for the new release:

Supported Clients

The following table provides the list of support Horizon clients:

Start Menu Shortcuts Configured Through the Admin Console

This feature improves the user experience by adding desktop and application shortcuts to the Start menu of Windows client devices.

You can use Horizon Administrator to create shortcuts for the following types of Horizon 7 resources:

  • Published applications
  • Desktops
  • Global entitlements

Shortcuts appear in the Windows Start menu and are configured by IT. Shortcuts can be categorized into folders.

Users can choose at login whether to have shortcuts added to the Start menu on their Windows endpoint device.

Watch this brief demonstration video of the new Desktop and Apps Shortcuts feature to see it in action:

Dedicated Desktop Support for Instant Clones

Upon the initial release of instant clones in Horizon 7, we supported floating desktop pools and assignments only. Further investments have been made to Instant Clone Technology that add support for dedicated desktop pools. Fixed assignments and entitlements of users to instant-clone machines is now provided as part of Horizon 7.3.

Dedicated instant-clone desktop assignment means that there is a 1:1 relationship between users and desktops. Once an end user is assigned to a desktop, they will consistently receive access to the same desktop and corresponding virtual machine. This feature is important for apps that require a consistent hostname, IP address, or MAC address to function properly.

Note: Persistent disks are not supported. Fixed assignments to desktops does not mean persistence for changes. Any changes that the user makes to the desktop while in-session will not be preserved after logoff, which is similar to how a floating desktop pool works. With dedicated assignment, when the user logs out, a resync operation on the master image retains the VM name, IP address, and MAC address.

Support for the Tesla P40 Graphics Card from NVIDIA

VMware has expanded NVIDIA GRID support with Tesla P40 GPU cards in Horizon 7.3.

HTML5 Video Redirection

This feature provides the ability to take the HTML5 video from a Chrome (version 58 or higher) browser inside a Windows VDI or RDSH system and redirect it to Windows clients. This feature uses Blast Extreme or PCoIP side channels along with a Chrome extension.

The redirected video is overlaid on the client and is enabled as well as managed using GPO settings.

Benefits include:

  • Supports generic sites such as YouTube, without requiring a server-side plugin.
  • Provides smooth video playback comparable to the native experience of playing video inside a browser on the local client system.
  • Reduces data center network traffic and CPU utilization on the vSphere infrastructure hosts.

Improved USB Redirection with User Environment Manager

The default User Environment Manager timeout value has been increased. This change ensures that the USB redirection Smart Policy takes effect even when the login process takes longer than expected.

With Horizon Client 4.6, the User Environment Manager timeout value is configured only on the agent and is sent from the agent to the client.

You can now bypass User Environment Manager control of USB redirection by setting a registry key on the agent machine (VDI desktop or RDSH server). This change ensures that smart card SSO works on Teradici zero clients. Note: Requires a restart.

HKLM\Software\VMware, Inc.\VMware VDM\Agent\USB uemFlags (REG_DWORD 1)

Blast Extreme Performance Counter Improvements

The Windows Agent PerfMon counters for the Blast Extreme protocol have been improved to update at a constant rate and to be even more accurate.

Counters include:

  • Imaging
  • Audio
  • CDR
  • USB
  • Virtual printing

Linux Virtual Desktops

Features and functions for Horizon 7 for Linux virtual desktops have been expanded:

  • KDE support – Besides RHEL/CentOS 6.x, the KDE GUI is now supported on RHEL/CentOS 7.x, Ubuntu 14.04/16.04, SUSE Linux Enterprise Desktop 11 SP4.
  • Support for the MATE interface on Ubuntu 14.04, Ubuntu 16.04.
  • Blast Extreme Adaptive Transport support.
  • vGPU hardware H.264 encoder support.

USB Redirection Support in Nested Mode

The USB redirection feature is now supported when you use Horizon Client in nested mode. When using nesting–for example, when opening RDSH applications from a VDI desktop–you can now redirect USB devices from the client device to the first virtualization layer and then redirect the same USB device to the second virtualization layer (that is, nested session).

Filtering Redirected Printers

You can now create a filter to specify the printers that should not be redirected with ThinPrint. A new GPO ADMX template (vmd_printing_agent.admx) has been added to enable this functionality.

By default, the rule permits all client printers to be redirected.

  • Supported attributes:
    • PrinterName
    • DriverName
    • VendorName
  • Supported operators:
    • AND
    • OR
    • NOT
  • Supported searching pattern is a regular expression.

Blast Extreme Improvements in CPU Usage

Now even lower CPU usage is achieved with adaptive Forward Error Correction algorithms. This clever mechanism decides how to handle error correction, lowering CPU usage within virtual desktop machines as well as on client endpoint devices.

Blast Extreme Adaptive Transport Side Channel

New support has been added for Blast Extreme Adaptive Transport side channels for USB and CDR communications. Once enabled, TCP port 32111 for USB traffic does not need to be opened, and USB traffic uses a side channel. This feature is supported for both virtual desktops and RDS hosts.

  • Feature is turned off by default.
  • Enable the feature through a registry key: HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Blast\Config\UdpAuxiliaryFlowsEnabled 1

Entitlement Restrictions Based on Machine Name

This feature allows IT administrators to restrict access to published applications and desktops based on both client computer and user. With client restrictions for RDSH, it is now possible to check AD security groups for specific computer names. Users only have access to desktops and apps when both the user and the client machine are entitled. For this release, the feature is supported only for Windows clients and works with global entitlements.

Pre-Launch Improvements

Pre-launch provides the ability to launch an empty (application-less) session when connecting to the Connection Server. The feature is now also available to Windows clients, in addition to macOS.

Also, it is no longer necessary to manually make changes to the client settings. You can configure automatic reconnection.

Blast Extreme Adaptive Transport Mode for iOS and macOS

With prior client releases, users were required to configure their Blast Extreme settings before they connected to the Connection Server. After a connection was established, the options to change the Blast Extreme setting—which included H.264, Poor, Typical, and Excellent—were unavailable.

With this release, users can change the network condition setting from Excellent to Typical or the reverse while inflight to sessions. Doing so also changes the protocol connection type between TCP (for Excellent) and UDP (for Typical).

Note: End users will not be able to change the network condition setting if Poor is selected before establishing a session connection.

Horizon Client for Windows

Horizon Client 4.6 updates include:

  • Additional command-line options for the new client installer – When silently installing the Windows client, using the /s flag, you can now also set:
    • REMOVE-SerialPort,Scanner – Removes the serial port, scanner, or both.
    • DESKTOP_SHORTCUT-0 – Installs without a desktop shortcut.
    • STARTMENU_SHORTCUT-0 – Installs without a Start menu shortcut.

  • Support for UNC paths with client drive redirection (CDR):
    • Allows remote applications to access files from a network location on the client machine. Each location gets its own drive letter inside the remote application or VDI desktop.
    • Folders residing on UNC paths can now be redirected with CDR, and get their own drive letter inside the session, just as any other shared folder.

Horizon Client for macOS

Horizon Client 4.6 updates include:

  • Apple macOS High Sierra day 0 support.
  • Users can select which monitors to use for VDI sessions and which to use for the local system.
  • Norwegian keyboard support and mappings are now available

Horizon Client for iOS

Horizon Client 4.6 updates include:

  • iOS 11 support
  • iOS split keyboard update – Removes the middle area in the split keyboard for a better view of the desktop
  • New dialog box for easy connection to a Swiftpoint Mouse

Horizon Client for Android

Horizon Client 4.6 updates include:

  • Android 8.0 Oreo support.
  • Server URL configuration – Allows administrators to configure a list of Connection Servers and a default Connection Server on Android devices managed by VMware AirWatch.

Android and Chrome OS Client Updates

Horizon Client 4.6 for Android and Horizon Client 4.6 for Chrome OS updates include:

  • Simple shortcuts – Users can right-click any application or desktop to add a shortcut to the home screen.
  • Webcam redirection – Integrated webcams on an Android device or a Chromebook are now available for redirection using the Real-Time Audio-Video (RTAV) feature.

HTML Access

HTML Access 4.6 updates include:

  • HTML Access on Android devices – Though HTML Access has fewer features than the native Horizon Client, it allows you to use remote desktops and published applications without installing software.
  • HTML Access page customization – Administrators can customize graphics and text and have those customizations persist through future upgrades.

Horizon Client for Linux

Horizon Client 4.6 updates include:

  • Support for Raspberry Pi 3 Model B devices:
    • ThinLinx operating system (TLXOS) or Stratodesk NoTouch operating system
    • Supported Horizon Client features include:
  • Blast Extreme
  • USB redirection
  • 264 decoding
  • 8000Hz and 16000Hz audio-in sample rate
  • RHEL/CentOS 7.4 support

Horizon Client for Windows 10 UWP

Horizon Client 4.6 updates include:

  • Network recovery improvements – Clients can recover from temporary network loss (up to 2 minutes). This feature was already available for Windows, macOS, Linux, iOS, and Android, and is now available for Windows 10 UWP.
    • Automatically reconnects Blast Extreme sessions
    • Reduces re-authentication prompts

We are excited about these new features in Horizon 7.3.1 and the Horizon Client 4.6.  We hope that you will give them a try.

If you can‘t send an email with iOS 11 and an Outlook.com or Exchange mail account

You might not be able to send email with an Outlook.com, Office 365, or Exchange account until you update to iOS 11.0.1.

If your email account is hosted by Microsoft on Outlook.com or Office 365, or an Exchange Server 2016 running on Windows Server 2016, you might see this error message when you try to send an email with iOS 11: “Cannot Send Mail. The message was rejected by the server.”

To fix the issue, update to iOS 11.0.1 or later.

Exchange Server 2016 Cumulative Update 7 (KB4018115) and Exchange Server 2013 Cumulative Update 18 (KB4022631)

The latest set of Cumulative Updates for Exchange Server 2016 and Exchange Server 2013 are now available on the download center.  These releases include fixes to customer reported issues, all previously reported security/quality issues and updated functionality.

Minimum supported Forest Functional Level is now 2008R2

In our blog post, Active Directory Forest Functional Levels for Exchange Server 2016, we informed customers that Exchange Server 2016 would enforce a minimum 2008R2 Forest Functional Level requirement for Active Directory.  Cumulative Update 7 for Exchange Server 2016 will now enforce this requirement.  This change will require all domain controllers in a forest where Exchange is installed to be running Windows Server 2008R2 or higher.  Active Directory support for Exchange Server 2013 remains unchanged at this time.

Support for latest .NET Framework

The .NET team is preparing to release a new update to the framework, .NET Framework 4.7.1.  The Exchange Team will include support for .NET Framework 4.7.1 in our December Quarterly updates for Exchange Server 2013 and 2016, at which point it will be optional.  .NET Framework 4.7.1 will be required on Exchange Server 2013 and 2016 installations starting with our June 2018 quarterly releases.  Customers should plan to upgrade to .NET Framework 4.7.1 between the December 2017 and June 2018 quarterly releases.

The Exchange team has decided to skip supporting .NET 4.7.0 with Exchange Server.  We have done this not because of problems with the 4.7.0 version of the Framework, rather as an optimization to encourage adoption of the latest version.

Known unresolved issues in these releases

The following known issues exist in these releases and will be resolved in a future update:

  • Online Archive Folders created in O365 will not appear in the Outlook on the Web UI
  • Information protected e-Mails may show hyperlinks which are not fully translated to a supported, local language

Release Details

KB articles that describe the fixes in each release are available as follows:

Exchange Server 2016 Cumulative Update 7 does not include new updates to Active Directory Schema.  If upgrading from an older Exchange version or installing a new server, Active Directory updates may still be required.  These updates will apply automatically during setup if the logged on user has the required permissions.  If the Exchange Administrator lacks permissions to update Active Directory Schema, a Schema Admin must execute SETUP /PrepareSchema prior to the first Exchange Server installation or upgrade.  The Exchange Administrator should execute SETUP /PrepareAD to ensure RBAC roles are current.

Exchange Server 2013 Cumulative Update 18 does not include updates to Active Directory, but may add additional RBAC definitions to your existing configuration. PrepareAD should be executed prior to upgrading any servers to Cumulative Update 18. PrepareAD will run automatically during the first server upgrade if Exchange Setup detects this is required and the logged on user has sufficient permission.

Additional Information

Microsoft recommends all customers test the deployment of any update in their lab environment to determine the proper installation process for your production environment. For information on extending the schema and configuring Active Directory, please review the appropriate TechNet documentation.

Also, to prevent installation issues you should ensure that the Windows PowerShell Script Execution Policy is set to “Unrestricted” on the server being upgraded or installed. To verify the policy settings, run the Get-ExecutionPolicy cmdlet from PowerShell on the machine being upgraded. If the policies are NOT set to Unrestricted you should use the resolution steps in KB981474 to adjust the settings.

Reminder: Customers in hybrid deployments where Exchange is deployed on-premises and in the cloud, or who are using Exchange Online Archiving (EOA) with their on-premises Exchange deployment are required to deploy the most current (e.g., 2013 CU18, 2016 CU7) or the prior (e.g., 2013 CU17, 2016 CU6) Cumulative Update release.

For the latest information on Exchange Server and product announcements please see What’s New in Exchange Server 2016 and Exchange Server 2016 Release Notes.  You can also find updated information on Exchange Server 2013 in What’s New in Exchange Server 2013, Release Notes and product documentation available on TechNet.

Exchange Server 2016 online training courses now available

Microsoft announced the release of four new edX online training courses for Microsoft Exchange Server 2016. If you plan to implement Exchange Server 2016 or Exchange Online, or if you want to make sure that your implementation was done right, the Exchange Server 2016 online training courses are for you.

Course offerings include:

Each Exchange course is targeted to the IT professional audience, with hands-on labs that reinforce student learning. Students are graded on completing each module, as well as on module assessment exams and a final course exam. A Certificate can be earned by completing each course with a passing grade. Courses are self-paced, allowing IT professionals to build Exchange skills at their own pace as their schedules permit.

The first course, CLD208.1x: Microsoft Exchange Server 2016 Infrastructure, is free. The remaining three courses are for-fee courses at $49 USD per course.

edX is a massive open online course (MOOC) provider that was developed by MIT and Harvard University. The Microsoft Learning Experiences team has created a wide range of online training courses for edX, and these four Exchange courses are the team’s latest Office releases. They are the first of seven courses that cover the core skills an Exchange administrator needs to proficiently design, implement and manage an Exchange 2016 and Exchange Online implementation.

CPU usage is high when you use RPC over HTTP protocol in Windows 8.1 or Windows Server 2012 R2

Consider the following scenario that takes Microsoft Exchange Server 2013 as an example:

  • The Mailbox server role is enabled in Exchange Server 2013.
  • Exchange mailboxes use extended MAPI to communicate with the Exchange Server.
  • The extended MAPI uses Microsoft RPC over HTTP (remote procedure call over HTTP) protocol.
  • Many clients (such as mobile devices) are dropping connections to the Exchange Server.

In this scenario, the CPU usage on the Exchange server may reach 100 percent.\

EXCHANGE 2013 CU17 AND EXCHANGE 2016 CU6

On June 27, 2017 Microsoft has released its quarterly updates for Exchange 2013 and Exchange 2016. The current version is now at Exchange 2013 CU17 (15.0.1320.4) and Exchange 2016 CU6(15.1.1034.26) . But this time there are some interesting things I’d like to point out.

A couple of days before the release of Exchange 2016 CU6 (15.1.1034.26)
Microsoft blogged about Sent Items Behavior Control and Original Folder Item Recovery. With the Sent Items Behavior Control, a message that’s sent using the Send As or Send on behalf of permission is not only stored in the mailbox of the user that actually sent the message, but a copy is also stored in the delegator mailbox sent items. This was already possible for shared mailboxes, but now it’s also possible for regular mailboxes (like manager/assistant scenarios).

The Original Folder Item Recovery feature is I guess on of the most requested features. In the past (before Exchange 2010) when items were restored after they were deleted, they were restored to their original location. With the Dumpster 2.0 that was introduced with Exchange 2010 this was no longer possible, and items were restored to the deleted items folder. In this case the items had to be moved manually to their original location. With the introduction of the Original Folder Item Recovery the restore of deleted items again takes place in the original folder.

Unfortunately, both Sent Items Behavior Control and Original Folder Item Recovery are only available in Exchange 2016 CU6 (and NOT in Exchange 2013 CU17).

When it comes to security TLS 1.2 is a hot topic. Microsoft is aware of this and working hard towards an Exchange environment that only uses TLS 1.2 (so that TLS 1.1 and TLS 1.0 can be disabled). We are not yet at that stage. Exchange 2016 CU6 does have improved support for TLS 1.2, but Microsoft is not encouraging customers to move to a TLS 1.2 environment only.

.NET Framework and Exchange server continues to be a difficult scenario. This is understandable, Exchange is just a consumer of Windows and .NET so the Exchange Product Group does not have much influence on the .NET (and Windows) Product Group.

Exchange 2016 CU6 does NOT support.NET Framework 4.7 at this moment, and you should NOT install .NET Framework on a server running Exchange 2016. Not before and not after the installation of Exchange 2016 CU6. This is also true for Exchange Server 2013 CU17. More information regarding .NET Framework and Exchange server can be found here: https://blogs.technet.microsoft.com/exchange/2017/06/13/net-framework-4-7-and-exchange-server/.

The .NET Framework 4.6.2 is supported by Exchange 2016 CU3 and higher and Exchange 2013 CU15 and higher. For a complete overview of which scenarios are supported, navigate to the Exchange Server Supportability Matrix on https://technet.microsoft.com/en-us/library/ff728623(v=exchg.150).aspx.
