Windows Server 2016 Features

  • Active Directory Federation Services: It is possible to configure AD FS to authenticate users stored in non-AD directories, such as X.500 compliant Lightweight Directory Access Protocol (LDAP) directories and SQL databases.
  • Windows Defender: Windows Server Antimalware is installed and enabled by default without the GUI, which is an installable Windows feature.
  • Remote Desktop Services: support for OpenGL 4.4 and OpenCL 1.1, performance and stability improvements; MultiPoint Services role (see Windows MultiPoint Server)
  • Storage Services: central Storage QoS Policies; Storage Replicas (storage-agnostic, block-level, volume-based, synchronous and asynchronous replication using SMB3 between servers for disaster recovery). Storage Replica replicates blocks instead of files; files can be in use. It’s not multi-master, not one-to-many and not transitive. It periodically replicates snapshots, and the replication direction can be changed.
  • Failover Clustering: cluster operating system rolling upgrade, Storage Replicas
  • Web Application Proxy: preauthentication for HTTP Basic application publishing, wildcard domain publishing of applications, HTTP to HTTPS redirection, Propagation of client IP address to backend applications
  • IIS 10: Support for HTTP/2
  • Windows PowerShell 5.0
  • Soft Restart, a Windows feature to speed up the booting process by skipping hardware initialization, and resetting software only.
  • Telnet server is not included.

Networking features

  • DHCP: as Network Access Protection was deprecated in Windows Server 2012 R2, in Windows Server 2016 the DHCP role no longer supports NAP
  • DNS:
    • DNS client: service binding – enhanced support for computers with more than one network interface
    • DNS Server: DNS policies, new DDS record types (TLSA, SPF, and unknown records), new PowerShell cmdlets and parameters
  • Windows Server Gateway now supports Generic Routing Encapsulation (GRE) tunnels
  • IP address management (IPAM): support for /31, /32, and /128 subnets; discovery of file-based, domain-joined DNS servers; new DNS functions; better integration of DNS, DHCP, and IP Address (DDI) Management
  • Network Controller, a new server role to configure, manage, monitor, and troubleshoot virtual and physical network devices and services in the datacenter
  • Hyper-V Network Virtualization: programmable Hyper-V switch (a new building block of Microsoft’s software-defined networking solution); VXLAN encapsulation support; Microsoft Software Load Balancer interoperability; better IEEE Ethernet standard compliancy

Hyper-V

  • Rolling Hyper-V cluster update: unlike upgrading clusters from Windows 2008 R2 to 2012 level, Windows Server Technical Preview cluster nodes can be added to a Hyper-V Cluster with nodes running Windows Server 2012 R2. The cluster continues to function at a Windows Server 2012 R2 feature level until all of the nodes in the cluster have been upgraded and the cluster functional level has been upgraded.
  • Storage quality of service (QoS) to centrally monitor end-to-end storage performance and create policies using Hyper-V and Scale-Out File Servers
  • New, more efficient binary virtual machine configuration format (.VMCX extension for virtual machine configuration data and the .VMRS extension for runtime state data)
  • Production checkpoints
  • Hyper-V Manager: alternate credentials support, down-level management, WS-Management protocol
  • Integration services for Windows guests distributed through Windows Update
  • Hot add and remove for network adapters (for generation 2 virtual machines) and memory (for generation 1 and generation 2 virtual machines)
  • Linux secure boot
  • Connected Standby compatibility

Nano Server

Microsoft announced a new installation option, Nano Server, a minimal footprint installation option of Windows Server. It excludes the graphical user interface, WoW64 (support for 32-bit software) and Windows Installer. It does not support console logon, neither locally nor via Remote Desktop Connection. All management is performed remotely via Windows Management Instrumentation (WMI) and PowerShell.
