Server 2008 routing & remote controll

[wishit]

Hello,

I have 3 servers are running Windows Server 2008 Active directory Then I run DHCP and DNS.

Server 1: 192.168.15.1

Server 2: 192.168.16.1

Server 3: 192.168.17.1

subnet 255.255.255.0

Now I want these 3 servers also a router. I know that you do this with routing and remote control. but my question is how you connect these three together. so your server 2 and 3 excisting domain controller can make.

I look forward to hearing from you
