Windows DHCP servers in HA does not replicate scope options?
Hi,
I have two Windows Server 2019 with DHCP configured running in failover/HA mode. The status of failover is normal. However, I notice if I add a scope option in one of the scopes on one DHCP server, it won't populate to the other DHCP server. Is this expected behavior? I thought the HA relationship should replicate everything at the scope level including scope options. Please advise. Thanks.
Yes, this is expected behavior. You can use PowerShell for this purpose.

Thanks, Dave Patrick!
Do you by any chance know the reason behind it? It does not quite make sense scope changes have to be replicated manually, considering replicating scope configs/data is part of Failover/HA relationship establishment in the first place. Keeping both servers in sync including the scope configurations should be the primary objective of the HA. Thanks.
Sorry but configuration changes are not automatically replicated.
