Announcing Windows Admin Center Preview 1902

Hello Windows Insiders,

Thank you for your continued interest in Windows Admin Center! This preview release builds on the previous 1812 version and adds new functionality including all-new software defined networking tools in the HCI solution, and one of the top-requested customer features: shared connection lists. For folks that use RDCman, we have published a small script that you may use to export your saved RDCman connections to a .CSV file which you can then import with PowerShell to maintain all your RDCman grouping hierarchy using tags.

Shared connections

We’re excited to release a highly-requested feature: a single connection list that can be shared across all users of a WAC gateway.

To add servers, clusters, and PCs as shared connections, you must be a WAC gateway administrator. Go to WAC Gateway Settings > Shared Connections, and then add servers, clusters, and PC as you normally would. You can tag servers in this pane as well, and these tags will appear for all users. The tags are immutable from the home “All Connections” page, meaning WAC users cannot change tags on shared server connections.

Software Defined Networking (SDN)

New Tool – Access Control List management (SDN)

With SDN, you can use access control lists (ACLs) to manage data traffic flow using Datacenter Firewall and ACLs on virtual subnets. You can enable and configure Datacenter Firewall rules by creating ACLs that get applied to a virtual subnet.

New Tool – Gateway Connection (SDN)

SDN Gateway is a software-based, multitenant, Border Gateway Protocol (BGP) capable router designed for Cloud Service Providers (CSPs) and Enterprises that host multiple tenant virtual networks using Hyper-V Network Virtualization.

In the Gateway Connection tool, you can manage and monitor your gateway connections in an SDN environment. It supports all three types of gateway connections – IPSEC, GRE and L3.

New Tool – Logical Network Management (SDN)

VM networks are abstract objects that act as an interface to logical networks. In a virtualized network environment, by using the VM networks, you can abstract virtual machines from the underlying logical network.

In the Logical Network tool, you can manage and monitor your logical network.

SDN Feature enhancement – Connect VM to VLAN or Virtual Network

Based on customer feedback, now you can choose to connect a VM to a VLAN or a Virtual Network in your SDN environment.

Known issues

Virtual machines – When adding a new VHD to a VM, and selecting the option to add a new, empty disk, you can’t save your changes. [20420660]

Network – If you have configured an Azure Network Adapter, the value under Microsoft Azure Virtual Network Gateway Address will be formatted as a hyperlink but leads to an invalid address. [20420185]
