Our firm is starting a small subsidiary company that must remain separate from our current company for compliance reasons. There will only be 5 users in this new company. They will be employees of our Firm (We will call this domain A and company A) and also employees of this separate entity (domain B and company B) and will split their time between the two.
My thought process was to create a new domain for company B and also create virtual workstations for each of the 5 employees. These virtual workstations will be in Domain B. Staff will RPD into these virtual workstations from their machines in domain A to do work for company B. For the most part they will be using e-mail, Internet and creating office documents on the company B virtual machines. They will keep these RDP sessions minimized while working on Company A items and then switch to the RDP session for the company B virtual machine when they need to perform work for company B.
I built a new Windows 2012 server for company B and created a new domain, domain B. This DC for company B is on the same subnet as the servers for company A. We will not be using DHCP for any of the Company B machines. Server or workstations. We will keep all of this static.
My question is how to configure DNS on domain A to allow name resolution to domain B? Can I create a new zone on the domain A DNS server for Domain B and add static entries for each of the virtual machines in domain B? This is really only needed to allow friendly names for the RDP sessions. should this be completed with forwarders on the domain A DNS server and if so how is this configured? I only want requests on domain A for domain B to be forwarded to the Domain B DNS server. I obviously don't want all DNS requests from domain A forwarded to domain B.
Thanks for your advice.
Have them on separate subnets and setup a trust between the two domains.
