This issue occurs if the computer that is running Communications Server 2007 or Microsoft Office Communications Server 2007 R2 is located in a domain that is part of a forest.
You can safely ignore this issue if the following conditions are true:
The domain has no Communications Server 2007 or Office Communications Server 2007 R2 users.
The domain has no computers that are running Communications Server 2007.
The Prep Domain step adds access control entries (ACEs) to universal groups. These ACEs grant permissions to host users and to manage users within the domain.
The Prep Domain step is required in all domains in which you want to deploy Communications Server, and it is required in any domains in which Communications Server users may be located. The Prep Domain step runs one time in each domain.
