Configure IIS for Office Communications Server 2007 R2

Communications Server 2007 R2

Topic Last Modified: 2009-03-26

Before you install Office Communications Server 2007 R2 Enterprise Edition in a consolidated configuration or Office Communications Server 2007 R2 Standard Edition, you must deploy Internet Information Services (IIS). For Enterprise pools in a consolidated configuration, you must deploy IIS before you can add servers to the pool. Web Components Server requires that IIS is installed.

If you install Office Communications Server 2007 R2 on a computer running IIS 7.0 on Windows Server 2008, you must configure IIS to run in IIS 6.0 compatibility mode, as described later in this topic.

For both Standard Edition servers and Enterprise pools, the Office Communications Server 2007 R2 installer creates virtual directories in IIS. For details, see IIS Requirements for Enterprise Pools and Standard Edition Servers.

If you install Office Communications Server 2007 R2 on a computer running IIS 6.0 on Windows Server 2003, you need to install only the following IIS services:

  • ASP.NET
  • World Wide Web Service

If you install Office Communications Server 2007 R2 on a computer running IIS 7.0 on Windows Server 2008, you need to configure IIS to run in IIS 6.0 compatibility mode. You need to install all of the following IIS services:

  • ASP.NET

    You must manually select this role on Windows Server 2008 Standard Edition.
  • Windows Authentication
  • IIS 6 Management Compatibility
    This group of services includes the following:
    • IIS 6 Metabase Compatibility
    • IIS 6 WMI Compatibility
    • IIS 6 Scripting Tools
    • IIS 6 Management Console

When you install and activate Office Communications Server 2007 R2 on a computer running Windows Server 2008, Setup disables kernel mode authentication in IIS to support Kerberos. As an alternative to disabling kernel mode authentication, you can configure IIS to use the Web application pool’s identity for internal virtual directories used by Office Communications Server. For details, see Internet Information Services (IIS) 7.0 Kernel Mode Authentication Settings.
