I have a concern of creating a new AD forest, let me explain what I need.
We have a forest with a domain with aa.co.uk with both forest and domain functional levels are Windows 2003. In this forest we have two domain controllers in two sites of 192.168.3.x and 192.168.4.x. At the head office we have a firewall with truested network of 192.168.3.x (One domain controller in this site) and the branch office has a firewall with 192.168.4.x trusted network (Other domain controller in this site). These two sites are connected though a Branch Office VPN connection.
Recently I have created a optional network at the branch office with 192.168.5.x IP range and it has only one server wich will be hosting an application. This server directly connected to the firewall optional port.
I am planning to create a new domain controller in a new forest in the optional network (192.168.5.x) with a new domain bb.co.uk, when I do so I can select new forest option through DCPROMO command.
At the moment I can access each trusted networks from the new optional network, so if I raised a new forest in the optional network, would this be affected the functionality of the existing forest?
Can any expert help me please?
Thanks in advance.
