Help with domain over vpn
Posted on 2011-03-10
I need some help before I begin my task. Here is the current setup. I have 3 sites all connected over a vpn. They are all using Cisco rvs4000 routers for the site to site tunnels. Currently each site is in a workgroup setting and receiving dhcp and dns by their respective routers. Site 1 has a single windows 2008 server. Each site also lan different local lan ip subnets. Site1: 10.0.0.X, Site2: 192.168.1.X, Site3 192.168.2.X. All clients are running Windows 7.
What I want to do is promote the server to a domain controller so I can centralize everything and invoke mandatory desktops, basically have all users log in and only see one single icon on their desktop. So, here is what I need to know.
If I promote this domain controller, what will be the impact if I leave DHCP and DNS on all the routers as-is?
Will I be able to join the remote clients to the domain without having any issues of finding the domain name?
Or, what should be the proper steps to take to do this correctly?
