Active Directory Infrastructure Requirements (2007 R2 Beta)

[This is preliminary documentation and is subject to change. Blank topics are included as placeholders.]

Before you start the process of preparing Active Directory Domain Services (AD DS) for Office Communications Server 2007 R2, ensure that your Active Directory infrastructure meets the following prerequisites:

• All domain controllers in the forest where you deploy Office Communications Server run Windows Server® 2003 with SP1, Windows Server 2003 R2, or Windows Server® 2008.
• All global catalog servers in the forest where you deploy Office Communications Server run Windows Server 2003 with SP1, Windows Server 2003 R2, or Windows Server 2008.
• All domains in which you deploy Office Communications Server are raised to a domain functional level of Windows Server 2003 or Windows Server 2008. You cannot deploy Office Communications Server 2007 R2 in a Microsoft Windows® 2000 mixed, Windows 2000 native, or Windows 2003 interim domain.
• The forest in which you deploy Office Communications Server is raised to a forest functional level of Windows Server 2003 or Windows Server 2008. You cannot deploy Office Communications Server 2007 R2 in a Windows 2000 mixed, Windows 2000 native, or Windows 2003 interim forest.

Office Communications Server 2007 R2 supports the universal groups in the Windows Server 2003 and Windows Server 2008 operating systems. Members of universal groups can include other groups and accounts from any domain in the domain tree or forest and can be assigned permissions in any domain in the domain tree or forest. Universal group support, combined with administrator delegation, simplifies managing an Office Communications Server deployment. For example, it is not necessary to add one domain to another to enable an administrator to manage both.
