Microsoft release new Windows Server 2019 Insider Preview Build 17709

Microsoft today released a new build of the Windows Server vNext Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience and Server Core in all 18 server languages, as well as a new build of the next Windows Server Semi-Annual Channel release in English. In addition, the first preview of Microsoft Hyper-V Server is included with the build.

Microsoft would like Insiders to try out In-place OS Upgrade and Application compatibility:

In-place OS Upgrade: (from Windows Server 2012 R2, Windows Server 2016 or a previous preview build). Build-to-Build upgrade is also supported.

Application compatibility: Microsoft would like to know if any server roles or applications stops working or fails to function as it used to.

Containers

Group Managed Service Accounts Microsoft improved the scalability and reliability of containers that use group managed service accounts (gMSA) to access network resources. You should see fewer authentication errors when using a single gMSA with multiple container instances. Additionally, you no longer need to set the container’s host name to be the same as the gMSA. Microsoft also fixed a bug that prevented testers from using gMSAs with Hyper-V isolated containers.

New base image: Windows

Microsoft adding a new base image to the Windows Server container collection. In addition to NanoServer and WindowsServerCore container images, the new Windows image is now available. This image carries even more components than its NanoServer and ServerCore siblings, meaning it can support applications that have additional API dependencies.

Known Issues

• [NEW] If a system is upgraded from preview release build 17692 to a more recent preview release, System Insights encounters errors when parsing or visualizing the prediction results. To resolve this issue, follow the instructions on System Insights known issues, or clean install a newer preview release.
• [NEW] Get-HgsAttestationBaselinePolicy, PowerShell cmdlet that generates an attestation baseline policy, fails with an error: “Failed to retrieve TPM information.”
• [NEW] On a recent preview release of Server Core, the Advanced Query Syntax (AQS) parser may fail if the default language and locale are changed to something other than US English. If the AQS parser is not working, search functionality in Exchange does not work.
• Creating or modifying environment variables by using setx on a system running NanoServer container fails. On an affected system, setx requires a specific path in the registry, HKCU\Environment\, to exist by default. You can work around this issue by changing where the variable is stored in the registry, or you can add the expected registry path before executing setx commands. To specify that the variable be set for system-wide use in HKLM rather than in HKCU, the default, add the /M switch to a setx command. To instead add the expected registry path, run reg add HKCU\Environment before executing setx commands.
• The Virtual Machine Management Service (VMMS) may experience an error, APPLICATION_FAULT_INVALID_POINTER_READ, in Cluster Manager.
• Editing or creating policies for AppLocker can cause the MMC snap-in to crash when generated rules for a packaged app.
