I have a question about creating a forest in a Windows Server 2008 R2 environment. Currently, we have our own domain which is part of another forest and our domain has a trust relationship with a second domain in that forest. We want to create a new forest for our needs and make our existing domain a member of the new forest. The other domain will be in its current forest. I want to know on how to proceed with creating a new forest and have/establish a trust relationship with the existing forest already in place in our organization. What are the things/steps I need to do to create new forest and establish the trust relationship with other forest. If there is a particular order to start then please let us know how we should proceed?
