Announcing Windows Server Insider Preview Build 17035

By / Software Engineer, Windows and Devices Group

Hello Windows Insiders!

Today we are releasing Windows Server Insider Preview Build 17035 to Windows Server Insiders. This build is the first preview build of the next Semi-Annual Channel release of Windows Server. For more information on the Semi-Annual channel, please see the Windows Server Semi-Annual Channel overview

New content available

Server Insiders now have your choice of ISO format or VHDX format. The images are pre-keyed –  no need to enter a key during setup.

Also new to Insiders, an early update to the Technical Preview of Project Honolulu. Project Honolulu is a flexible, lightweight browser-based customer-deployed platform and solution for Windows Server management scenarios for troubleshooting, configuration and maintenance. Project Honolulu Technical Preview 1711 Build 01003 is now available to Insiders before the public and is our first update since our initial Technical Preview 1709 released for Ignite.

Symbols are available on the public symbol server – see Update on Microsoft’s Symbol Server blog post and Using the Microsoft Symbol Server. As before, matching Windows Server container images will be available via Docker Hub. For more information about Windows Server containers and Insider builds, click here.

This Server Insider pre-release build will expire on July 2nd, 2018. For the best experience, the Windows Server team recommends a clean install.

What’s New in Build 17035 for Windows Server

  • Storage Spaces Direct (S2D) is enabled. Storage Spaces Direct is the foundation of our hyper-converged solution and we’re continuing to evolve it. In this preview build we not only brought it back, but we’re adding some new and important updates to it – such as support for Data Deduplication, a commonly requested feature for Storage Spaces Direct and ReFS. Starting with this build, Data Deduplication will reduce the data footprint by up to 50%.
  • Developers can now use localhost or loopback (127.0.0.1) to access services running in containers on the host

What’s New in Project Honolulu Technical Preview 1711 Build 01003

NOTE: Please manually Refresh your browser (F5) on first launch if upgrading from version 1709.

Remote Desktop

With the remote desktop tool in the Server Manager solution, you can connect to your machine to complete scenarios that are not yet supported natively in Honolulu. If you want to configure a feature that has no GUI tool, connect with Remote Desktop and open PowerShell!

Windows 10 Client Management

You can now add Windows 10 client machines as connections in Honolulu, and manage them with a subset of tools in the “Computer Management” Solution

Switch Embedded Teaming (SET)

Short of SCVMM, there was previously no GUI experience to configure Switch Embedded Teaming (SET), a new feature released in Windows Server 2016. You will find this feature in the Virtual Switches tool.

Data grid performance improvements

We have updated the grid in the Certificates and Events tools to a more performant control which is able to handle large datasets without a loss in performance. In the next release, it will be updated across all tools. In the Events tool, the data is streamed in as it loads, which can lead to a shorter loading time than the in-box tool when working with channels that contain many events.

Removed: LAPS in Service mode

We have removed the ability to use LAPS when Project Honolulu is deployed as a Server service.  You may still use LAPS when you install Honolulu on Windows 10.

How to Download 

To obtain the Insider software downloads, registered Insiders may navigate directly to the Windows Server Insider Preview download page.  If you have not yet registered as an Insider, see GETTING STARTED WITH SERVER on the Windows Insiders for Business portal.

It’s all about your feedback! 

The most important part of a frequent release cycle is to hear what’s working and what needs to be improved, so your feedback is extremely valued. Use your registered Windows 10 Insider device and use the Feedback Hub application. In the app, choose the Server category and then the appropriate subcategory for your feedback. Please indicate what build number you are providing feedback on.

Known issues with Windows Server build 17035

  • [NEW] The base filtering engine (BFE) service may fail to start, which prevents the Windows Defender firewall (MpsSvc service) from starting.
  • A system crash may occur because of a kernel security check failure (bug check 0x139) from a corrupt list entry in a deferred free pool.
  • An application may crash because of a heap entry corruption error (0xC0000374) in the health attestation configuration service provider (CSP) library (Hascsp.dll).
  • Testing of the Windows core may fail because of a timeout while attempting to load the test libraries.

Known Issues with Project Honolulu Technical Preview 1711 Build 01003

This list captures issues in the new features only. You can find the complete list of known issues here.

If you encounter bugs (in the new features only) that are not captured here, please post on the Project Honolulu space on Windows Server Tech Community.

Remote Desktop

  • The Remote Desktop tool does not currently support any text, image, or file copy/paste between the local desktop and the remote session.
  • To do any copy/paste within the remote session, you can copy as normal (right click + copy or Ctrl+C), but paste requires right click + paste (Ctrl+V does NOT work)
  • Opening the web browser’s debugger while a Remote Desktop session is active may cause your computer to crash. Don’t do it.
  • You cannot send the following key commands to the remote session:
    • Ctrl+Alt+End / Ctrl+Alt+Del
    • Alt+Tab
    • Function keys
    • Windows Key
    • PrtScn

Windows 10 Client Management

  • If you try to add a Windows PC connection, but the add connection dialog tries to add it as a server, refresh your browser. If the problem persists, clear your browser cache.
  • When you try to manage the localhost, you will be prompted to elevate the gateway process. If you click no in the User Account Control popup that follows, Honolulu won’t be able to display it again. In this case, exit the gateway process by right-clicking the Project Honolulu icon in the system tray and choosing exit, then relaunch Project Honolulu from the Start Menu.
  • Windows 10 does not have WinRM/PowerShell remoting on by default.

To enable management of the Windows 10 Client, you must issue the command Enable-PSRemoting from an elevated PowerShell prompt.

You may need to update your firewall to allow connections from outside the local subnet:

Set-NetFirewallRule -Name WINRM-HTTP-In-TCP –RemoteAddress Any

For more restrictive networks scenarios, please refer to this documentation.

Switch Embedded Teaming (SET)

  • When adding NICs to a team, they must be on the same subnet.

As with all networking configuration options in Project Honolulu, configuring this feature will cause a temporary loss in connectivity as the server’s networking stack restarts. This will generate errors that can safely be ignored.

Terms of Use: All pre-release software made available to you via the Windows Server Insider program are governed by the Insider Terms of Use, which takes precedence over any license agreement that may be in the product.

No downtime for Hustle-As-A-Service,
