Looking to raise my domain functional level to Windows 2012. We have two domains on our network Domain A comprises only one server. Period. No client computers are joined to the domain. It was setup to handle files and software licensing for engineering team. Domain B is our main domain. Our computers logon to Domain B.
The domains have been setup with a two-way trust. When I setup the two way trust, I was prompted to select the functional level of the trust relationship. Domain A is a Windows Server 2008 R2. Domain B has 2 Windows Server 2012 domain controllers. If I upgrade the domain functional level of Domain B to 2012, will this negatively affect the trust relationship between both domains?
Currently, users logged on to Domain B are able to access shared/network drives on A, even though they are only created as users, on Domain B.
