What is exciting in Windows vNext 1906 Preview Copy

The first preview version published after the public release in April, the Windows 1906 Administration Center preview includes several new preview features

Update tool

You can now choose individual Windows updates to install, depending on user requests.

Windows Management Center connectivity settings

Users in very disconnected environments indicate that they prefer to set parameters in the Windows Administration Center that will allow them to determine that they are offline. There are no notifications about Azure Hybrid features, update extensions, etc. Actions that require public access to the Internet.

To try this, enter msft.sme.shell.connectivity as the test key in Settings -> Development -> Advanced, and then visit the new Connectivity Configuration item. You can choose a gateway to restrict online access, or Azure and Gateway if you want to access only Azure features, but nothing else on the public Internet. In the upcoming version, this menu item will also give you a complete list of URLs so that you can configure your firewall to block all default traffic and explicitly only allow certain traffic to known services.

Virtual machine tool:

• Import / Export virtual machines: add the Import / Export button to the Virtual Machine tool to import and exchange virtual machines from virtual machines to local volumes or to share files remotely. When importing virtual machines, you have the option to create a new virtual machine ID and copy virtual machine files or use them in the field.
• [Known problem] When importing a virtual machine and copying files from a virtual machine, if you choose local volume or volume with the cluster as the destination, it will be stored in the root volume folder instead of "Hyper-V". folder. This will be fixed in the next version. For now, you can use the Browse button to manually access the folder where you want to import the virtual machine.
• Mark virtual machines: Similar to the user interface to mark connections in the Windows Administration Center, you can now tag virtual machines on the Hyper-V server! On the Inventory tab of the virtual machine tool, the "Edit label" button is added to manage the label. This tag is stored on the Hyper-V host server and can be seen by other administrators.
• [Known Issues] Mapping of virtual machine labels has not been supported in cluster failover or hyper-converged cluster user interfaces. Tags will not appear in clustered virtual machine views, and tag management in this view can overwrite or accidentally delete existing tags.
• Performance improvements: significant improvements in performance have been made to reduce page load times in virtual machine tools.

Azure Integrations Improvements and New Development

When you add a Windows server or computer to your connection list, you have a new option to access Azure and explore your Azure source in searching for a particular server or computer.
[Known Issues] Currently, Windows Administration Center only mentions Azure resources, but cannot guarantee connectivity.

Windows Administration Center for ecosystem developers: You will find a new menu item: The Performance Profile in the Windows Administration Center configuration under the Development heading. This new tool will record your browsing session, this will track the time of each page request and each loading, so you can identify opportunities to improve performance.

Known issues - Preview Windows Administration Center 1906

• Network: If you configure an Azure network adapter, the value below the Microsoft Gateway virtual network gateway address will be formatted as a hyperlink, but will result in an invalid address. [20420185]
• Azure Onboarding Management Update: If you have installed an agent or MMA agent with new integration for the Azure Monitor, you cannot integrate the server with Azure Update Management through the Windows Administration Center user interface. If you have configured Azure Update Management (through an Administration Center or other methods), you can still connect to the server for the Azure Insight Monitor VM VM solution through the Center user interface. Windows Administration.
• Chrome users can see 403 WAC responses blocked after an update. The solution is to close all open the Chrome tab (make sure the chrome.exe process is not running). After restarting Chrome, everything will work normally. Windows forums have an error message explaining it, but Chrome users with multiple tabs in the Windows Management Center open during the update will not see the message.

Windows Server Bug Fixes and Patches

• Resolve problems when the last "out username" local users cannot be registered, even when the user has accessed a shared network server.
• Fixed an issue when trying to update the default server to Datacenter Server, resulting in the error "Error: 1168. An error occurred while applying the configuration to the target edition component." An update cannot continue.
• The problem is solved when the domain trust is damaged when the trash basket is configured in a trusted domain.

Windows Server Known Problems

• The use of ntdsutil.exe to move files in an Active Directory database may fail with the following error message: "File transfer failed with the <original_full_path_db> source and the destination <new_db_db> with error 5 (Access denied".
• Automatic connections that are configured by the login script might not work correctly
• The status /online/offline file icon status bar may not indicate a certain status. OfflineFiles event controller registration shows the current file status.
• PowerShell can report incorrect NdisPhysicalMedium results on an IPO adapter
• Only applies to FOD MMC.exe FOD applications: Some Active Directory user add-ons and computers added to the same instance of MMC.exe can display inconsistent or missing add-on data after adding additional columns to the display user interface. Workaround: for user interface user administration, use a separate MMC for each additional ADUC (DSA.MSC).
• Scheduled startup tasks may fail. An event is recorded, ID 101 with an ERROR_LOGON_FAILURE error code if an error occurs.
• DCPromo fails if the physical interface metrics in the NIC are greater than the loopback interface
• Domain controllers rename the wrong attribute update in AD and let the data become orphaned (ValidateSPNsAndDNSHostNameActual). This can be replicated by adding a new domain name that fully meets the requirements, sets it as main, restarts the domain controller and then deletes the current full domain name. When checking the MSDS-AdditionalDnsHostName attribute, the MSDS-AdditionalSamAccountName and servicePrincipalName will be incorrect.
• After disabling and reactivating the SR-IOV function on a Linux virtual machine network adapter, Windows can report "Failed to apply changes to the network adapter". The details will say "The Hyper-V VM management service experienced an unexpected error: the call was canceled by the Message Filter. (0x80010002)". The secondary effect of this failure is that the virtual machine will remain dead when the virtual machine is turned off and cannot be restarted without restarting the power supply.
• When the VM driver is used, after the last restart, the VM Controller deployment process is not visible.

In the next patch or release all the issues should get fixed, we hope. You can Tweet on your feed.
