This topic describes the prerequisites and requirements for the deployment of Office Communications Server 2007 R2 Standard Edition.

You can deploy Standard Edition in your network after your Active Directory Domain Services (AD DS) has been prepared for Office Communications Server 2007 R2. We recommend that you deploy at least one Office Communications Server 2007 R2 pool or server in your internal network before you deploy any other servers in an Office Communications Server 2007 R2 topology. At any time, you can deploy new Standard Edition servers in your environment by creating a new pool for each new server.

In this release, unified communications applications are automatically installed. The applications can be activated when you deploy Standard Edition, but you can also deploy unified communications applications later.

If you plan to deploy Office Communications Server 2007 R2 Archiving Server or Office Communications Server 2007 R2 Monitoring Server to enable archiving or monitoring, you can deploy either server before you deploy Standard Edition. If you deploy Archiving Server or Monitoring Server before you configure your server, you can configure the archiving and monitoring settings during server configuration.

You can deploy unified communications clients and devices in your environment before or after you deploy Office Communications Server, but we recommend that you deploy clients after you deploy at least one Office Communications Server or pool to host users. Clients cannot be used until servers are configured and running and user accounts have been enabled for Office Communications Server.

Prerequisites for Standard Edition

Office Communications Server 2007 R2 is available only in a 64-bit edition, which requires 64-bit hardware and the 64-bit edition of Windows Server. A 32-bit edition is not available with this release. The exception is Office Communications Server Administrative Tools, which is available both in a 64-bit and a 32-bit edition.

The following operating system updates are prerequisites for deploying Office Communications Server 2007 R2:

  • Microsoft Knowledge Base article 953582, "You may be unable to install a program that tries to register extensions under the IQueryForm registry entry in Windows Server 2008 or in Windows Vista" at http://go.microsoft.com/fwlink/?LinkId=131392 .

    This update must be installed before you install Office Communications Server 2007 R2 Administrative Tools onlyin the following situations:

    • On computers running Windows Vista, on which you install Remote Server Administration Tools (RSAT).

    • On computers running Windows Server 2008, if the server role Active Directory Domain Services role is added.

  • Microsoft Knowledge Base article 953990, “AV at mscorwks!SetAsyncResultProperties” at http://go.microsoft.com/fwlink/?LinkId=131394 .

    This update applies to Windows Server 2003 SP2 and Windows Server 2008.

For details about Standard Edition operating system and hardware requirements, see Office Communications Server Infrastructure Requirements.

AD DS must be prepared for Office Communications Server 2007 R2 before you can deploy Office Communications Server 2007 R2 Standard Edition. Standard Edition also requires that the following be deployed in your environment:

  • Domain Name System (DNS)

  • Public key infrastructure (PKI)

  • Microsoft .NET Framework 3.5 (64-bit)

  • Microsoft Visual C++ 2008 redistributable

  • IPv4 addresses and networking protocols

You must prepare certificates using the PKI so that you can configure mutual TLS (MTLS) between Office Communications Server servers. Setup prompts you to install the .NET Framework and the Visual C++ 2008 redistributable, and it automatically installs them if they are not already installed on the computer.

For details about these prerequisites, see Environmental Requirements.

Best Practices

We strongly recommend that you read Planning and Architectureto determine the features, functionality, and topology required by your organization before you begin deploying Standard Edition.
