Adding another windows 2008 dc for dhcp and dns redundancy
Posted on 2010-09-13
I currently have a windows 2008 domain controller that also serves as a dhcp and dns server. I'm considering adding another virtual machine 2008 domain controller to serve as a backup. When I configure new vm, do I just match the total scope and options to match the original domain controller?
Is that the way to go or do I create 2 separate scopes?
i.e. PDC Scope = 10.0.0.11-10.0.0.160 BDC Scope = 10.0.0.161-10.0.0.200
Can I do this while PCs are connected to LAN? How do I switch over ?
Do I just configure it and let it get on with it or do I have to stop
and start DHCP Server services on both machines?
Any other pitfalls to watch for?
