Domain Controller with multiple network interfaces
I have two DCs which have network interfaces on two or three different VLANs. I only need a response on the corporate LAN, but the other VLAN is for VOIP and one server has a third network for VLANed...

Sounds good, just don't multi-home your domain controllers.

Multi-homing a domain controller will always cause no end to grief for active directory domain DNS. Better option is to install the viop software on another instance of windows.

- TimGowenJul 06, 2021Copper ContributorThank you... The other networks are on the DC because it's also doing DHCP. Should I have a separate DHCP server in the VOIP VLAN to provide addressing to the phones?

Better option is to use layer 3 routing hardware for this purpose. If you must do it on windows then use another member server for this role.
- TimGowenJul 06, 2021Copper ContributorThanks. We have L3 switches so I'm not sure what has been done. Can you refer me to any best practice?
