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.
Note: The operating system running on the domain controllers can be either 32-bit edition or 64-bit edition. - 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.
Note: To change your domain or forest functional level, see “Raising domain and forest functional levels” at http://go.microsoft.com/fwlink/?LinkId=125762 .
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 the management of an Office Communications Server deployment. For example, it is not necessary to add one domain to another to enable an administrator to manage both.
