How to set up DHCP failover on Windows Server

Redundancy is essential for dealing with both planned and unplanned outages, and that includes having redundant dynamic host-configuration protocol (DHCP) servers to allow uninterrupted dynamic assignment of IP addresses.For those working in Windows environments, there are currently two options for setting up redundant DHCP servers: a failover scenario with a main server paired with another in hot standby; and a load-balancing scenario in which two DHCP servers actively handle client requests.

Microsoft adds resiliency, redundancy, security to Windows Server 2019

With Windows Server 2019, Microsoft is adding resiliency and redundancy enhancements to the Shielded Virtual Machines security controls it introduced with Windows Server 2016.Shielded VMs originally provided a way to protect virtual machine assets by isolating them from the hypervisor infrastructure and could also help prove to auditors that systems were adequately isolated and controlled. Now Shielded VM enhancements in Window Server 2019 provide real-time failback configurations and host- and policy-based security improvements.[ Don’t miss customer reviews of top remote access tools and see the most powerful IoT companies . | Get daily insights by signing up for Network World newsletters. ]
