Updated ouut-of-band (OOB) updates are released for March 2024 for Windows Server Domain Controllers

Microsoft has identified an issue that affects Windows Server domain controllers (DCs), and has expedited a resolution that can be applied to affected devices. Out-of-band (OOB) updates have been released for some versions of Windows today, March 22, 2024, to addresses this issue related to a memory leak in the Local Security Authority Subsystem Service (LSASS). This occurs when on-premises and cloud-based Active Directory domain controllers service Kerberos authentication requests.

This issue is not expected to impact Home users, as it is only observed in some versions of Windows Server. Domain controllers are not commonly used in personal and home devices.

Updates are available on the Microsoft Update Catalog only. These are cumulative updates, so you do not need to apply any previous update before installing them, and they supersede all previous updates for affected versions. If your organization uses the affected server platforms as DCs and you haven’t deployed the March 2024 security updated yet, we recommend you apply this OOB update instead. For more information and instructions on how to install this update on your device, consult the below resources for your version of Windows:

  • Windows Server 2022: KB5037422
  • Windows Server 2019: Available soon
  • Windows Server 2016: KB5037423
  • Windows Server 2012 R2: KB5037426

Note: The OOB release for Windows Server 2019 will be released in near term.

Upcoming change (March 2020) – Microsoft to disable use of unsigned LDAP port 389

In March 2020, Microsoft is going to release a update which will essentially disable the use of unsigned LDAP which will be the default. This means that you can no longer use bindings or services which binds to domain controllers over unsigned ldap on port 389. You can either use LDAPS over port 636 or using StartTLS on port 389 but it still requires that you addd a certificate to your domain controllers. This hardening can be done manually until the release of the security update that will enable these settings by default.

How to add signed LDAPS to your domain controllers

You can read more about the specific change here –> https://support.microsoft.com/en-us/help/4520412/2020-ldap-channel-binding-and-ldap-signing-requirement-for-windows you can also read more here –> https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/ldap-channel-binding-and-ldap-signing-requirements-update-now/ba-p/921536

After the change the following features will be supported against Active Directory.

clipboard_image_0.png

How will this affect my enviroment?

Clients that rely on unsigned SASL (Negotiate, Kerberos, NTLM, or Digest) LDAP binds or on LDAP simple binds over a non-SSL/TLS connection stop working after you make this configuration change. This also applies for 3.party solutions which rely on LDAP such as Citrix NetScaler/ADC or other Network appliances, Vault and or authentication mechanisms also rely on LDAP. If you haven’t fixed this it will stop working. This update will apply for all versions.

Windows Server 2008 SP2,
Windows 7 SP1,
Windows Server 2008 R2 SP1,
Windows Server 2012,
Windows 8.1,
Windows Server 2012 R2,
Windows 10 1507,
Windows Server 2016,
Windows 10 1607,
Windows 10 1703,
Windows 10 1709,
Windows 10 1803,
Windows 10 1809,
Windows Server 2019,
Windows 10 1903,
Windows 10 1909

How to check if something is using unsigned LDAP?

If the directory server is configured to reject unsigned SASL LDAP binds or LDAP simple binds over a non-SSL/TLS connection, the directory server will log a summary under eventid 2888 one time every 24 hours when such bind attempts occur. Microsoft advises administrators to enable LDAP channel binding and LDAP signing as soon as possible before March 2020 to find and fix any operating systems, applications or intermediate device compatibility issues in their environment.

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.

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.

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 2016/2013/2010 Updates March 2017

Today, the Exchange Team released the March updates for Exchange Server 2013 and 2016, as well as Exchange Server 2010 and 2007. The latter will receive its last update, as Exchange 2007 will reach end-of-life April 11, 2017.

As announced in December updates, Exchange 2013 CU16 and Exchange 2016 CU5 require .NET 4.6.2. The recommended upgrade paths:

  • If you are still on .NET 4.6.1, you can upgrade to .NET 4.6.2 prior of after installing the latest Cumulative Update.
  • If you are on .NET 4.52, upgrade to Exchange 2016 CU4 or Exchange 2013 CU15 if you are not already on that level, then upgrade to .NET 4.6.2, and finally upgrade to the the latest Cumulative Update.

The Cumulative Updates also include DST changes, which is also contained in the latest Rollups published for Exchange 2010 and 2007.

Exchange 2013 CU16 fixes:

  • KB4013606 Search fails on Exchange Server 2016 or Exchange Server 2013

Notes:

Exchange 2016 CU5 doesn’t include schema changes, however, Exchange 2016 CU5 as well as Exchange 2013 CU16 may introduce RBAC changes in your environment. Where applicable, use setup /PrepareSchema to update the schema or /PrepareAD to apply RBAC changes, before deploying or updating Exchange servers. To verify this step has been performed, consult the Exchange schema overview.

When upgrading your Exchange 2013 or 2016 installation, don’t forget to put the server in maintenance mode when required. Do note that upgrading, before installing the Exchange binaries, setup will put the server in server-wide offline-mode.

Using Windows Management Framework (WMF)/PowerShell version 5 on anything earlier than Windows Server 2016 is not supported. Don’t install WMF5 on your Exchange servers running on Windows Server 2012 R2 or earlier.

When using Exchange hybrid deployments or Exchange Online Archiving (EOA), you are allowed to stay at least one version behind (n-1).

  • If you want to speed up the update process for systems without internet access, you can follow the procedure described here to disable publisher’s certificate revocation checking.
  • Cumulative Updates can be installed directly, i.e. no need to install RTM prior to installing Cumulative Updates.
  • Once installed, you can’t uninstall a Cumulative Update nor any of the installed Exchange server roles.
  • The order of upgrading servers with Cumulative Updates is irrelevant.

Caution: As for any update, I recommend to thoroughly test updates in a test environment prior to implementing them in production. When you lack such facilities, hold out a few days and monitor the comments on the original publication or forums for any issues.

Don’t Deploy Exchange Server 2016 on Windows Server 2016 For Now Due to Stability Issues

Since the release of Exchange Server 2016 Cumulative Update 3 (CU3), which added support for installing Exchange 2016 onto Windows Server 2016 servers, there’s been a series of reports in support forums and blog comments about errors that customers are seeing.

Now Microsoft has acknowledged that there is in fact a known issue, and there is no current workaround for it.

If you attempt to run Microsoft Exchange 2016 CU3 on Windows Server 2016, you will experience errors in the IIS host process W3WP.exe. There is no workaround at this time. You should postpone deployment of Exchange 2016 CU3 on Windows Server 2016 until a supported fix is available.

That’s all the detail that has been publicly released by Microsoft at this time, but the guidance is clear. You should deploy Exchange 2016 only on Windows Server 2012 R2 until further notice.
