Hello, We currently run a flat network with around 600 hosts. We run 10 network switch stacks comprising of three switches each, All stacks are connected to the core stack via direct fibre link in a star formation. All servers are directly connected to the core switches. We are looking to break up the network into 10 subnets, One per stack. Each stack has a switch that will act as a router to other parts of the network. The new setup includes a number of VLAN's.

My question is this, What do I need to do to the DHCP, DNS and Active Directory servers(DC's) to make sure they can handle traffic and requests from workstations sitting in different subnets. I'm aware I need tonforward DHCP requests from each switch stack router and create an IP Scope per subnet. Not so clear on what needs done on the DNS server(Reverse lookup etc, Zones) and DC's. Subnets will look something like this:

192.168.100.0/24 servers 255.255.255.0
192.168.101.0/24 stack 1
192.168.102.0/24 stack 2
192.168.103.0/24 stack 3
192.168.104.0/24 stack 4
192.168.105.0/24 stack 5
.
.
and so on .....

The current network looks like this

192.168.100.1 - 192.168.103.254 with servers sitting on 100.1 - 100.254 IP range
Servers running W2k8 R2, We run 2 DC's, 3 DNS servers, 2 DHCP servers.

Can give me an idea of what needs done on the server side to make sure DHCP requests are processed, DNS resolves in all subnets and Active Directory authentication works as it should.

All servers need to sit within IP range 192.168.100.10 - 192.168.100.20 mask 255.255.255.0
