At a minimum,
Microsoft recommends using Windows Server 2003 SP1R, but you should consider going
ahead with Windows Server 2003 R2. The minimum supported confi guration for Active
Directory is Windows 2000 SP4 in Native Mode. Version 2 of the .NET Framework is
required by OCS 2007, and any server running IIS must be running Version 6. The minimum
version of SQL Server is SQL Server 2000 SP4 or SQL Server 2005 SP1. The recommended
version is SQL Server 2005 SP2.
Planning an OCS 2007 Installation
We all know that planning is essential to successful deployment. In fact, it is always good
to keep in mind the Seven Ps: Prior Planning and Practice Prevent Pretty Poor
Performance. (For those of you familiar with the Seven Ps, I??™ve modifi ed the fi fth P to
make it suitable for a general audience.) The new OCS 2007 deployment tool, combined
with new wizards for many of the more common, everyday tasks such as confi guring
pools and obtaining certifi cates, greatly simplifi es the process of installing, confi guring, and
activating OCS 2007. But the deployment tool and wizards don??™t take the place of planning
(keep in mind those Seven Ps); they simply make it much easier to carry out your plans.
Microsoft??™s OCS Planning Guide suggests that you follow these steps when planning your
installation:
1. Determine key planning decisions The fi rst thing you and your staff need to
consider before choosing your topology is your main decision points.
2. Select your topology You should probably consider several different sample
deployments based on the size and functionality you??™re seeking.
