Microsoft releases Windows Server 2019 Insider build 17709

Another fresh Windows Server 2019 Insider preview build is now available.

Microsoft has shipped out another new Windows Server 2019 Insider preview build for testers to check out. Today’s release moves things up to build number 17709 and includes a couple of new features to check out, along with several known issues to be aware of.

What’s new

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
