Windows Server 2019 gets a new Insider build as 17709 is released

Microsoft has just released new preview builds for Windows Server 2019 and Windows Server version 1809, the two upcoming releases in the Long-Term Servicing Channel (LTSC) and Semi-Annual Channel. The build number for this latest release is 17709, and it brings two new features related to Containers.

As usual, Windows Server Insiders can download the new bits from the Windows Server Insider Preview download page, and learn more about the new features below:

Group Managed Service Accounts

We’ve 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. We also fixed a bug that prevented you from using gMSAs with Hyper-V isolated containers.

New base image: Windows

We’re 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. To learn more and get started, go to https://aka.ms/windowscontainer.

As a reminder, the previous Insider release introduced the first version of Microsoft Hyper-V 2019, and this feature is still available in this latest preview build of the server OS. You can check this page to see the full list of new features introduced in earlier builds of Windows Server 2019.
