Env:

One Domain Controller (DC1).
Server2 Just a member didn't promote it to a DC.

Case:
—-
I'm trying to setup a DHCP Failover (Hot Standby)

CMDLET:
——
Add-DhcpServerv4Failover -ComputerName Server2 -Name "StandbyFilover" -PartnerServer "DC1" -ScopeId "$SopeID" -ServerRole Standby -AutoStateTransition:$True -StateSwitchInterval 00:05:00

Result:
——
when I stopped the DHCP server on DC1 didn't switch over to Server2.
Is there something wrong with my PS Command let ?

I'd use the GUI (MMC) to verify that it's all set up correctly. There's a lot of pre-requisites beyond just running the command.

Here's the result from 2 types of configurations (1st) from PowerShell, Second from GUI
Using Get-DhcpServerv4Failover | select *

Strangely with PowerShell CMDLET shows the partner server and Primary Servers as the Partner Server (Server2)
