I have setup an Active Directory on a server and with two client PCs. Now I want to setup another Active Directory (new domain name and new DNS server) on another server and connect a couple of new PCs to the new domain. All are virtual machines pretty much and all use the same network with the same IP addresses 192.168.1.x Will I have any problems? Obviously I am going to keep them isolated, i.e. the ones part of the new domain won't even know about the old domain with a different name and clients lurking around on the same network with similar IP addresses. And of course this will be temporary until the new domain is all tested and up and running. Then the old domain server and clients will be put to death Thanks.
