DHCP Failover Auto Config Sync (DFACS)
We have already gone through some limitations of DHCP Fail-over in windows server 2012, if you have missed my previous article here is the link
Microsoft provided a solution to overcome some of the limitation, which is a PowerShell script which is detailed below in this article.
Anyway this limitations are not there in the windows server 2016 release
DHCP Failover on windows Server 2012 is a good alternative for DHCP in a Windows failover cluster and Split scope DHCP. But If the user makes any changes in any property/configuration (e.g. add/remove option values, reservation) of a failover scope, he/she needs to ensure that it is replicated to the failover server.
Windows Server 2012 provides functionality for performing this replication using DHCP MMC as well as PowerShell. But these require initiation by the user.
This requirement for explicitly initiating replication of scope configuration can be avoided by using a tool which automates this task of replicating configuration changes on the failover server. DHCP Failover Auto Config Sync (DFACS) is a PowerShell based tool which automates the synchronization of configuration changes. This document is a guide to using DFACS.
