After you have set up the hardware and system infrastructure, you need to install the appropriate Windows operating systems and updates, in addition to all other prerequisite software on each server that you are deploying. This includes each Lync Server 2013 server role and any additional infrastructure servers or servers running SQL Server that are required for your deployment.

Note:
This section describes installation of operating systems and prerequisite software for internal servers. If you are deploying Edge Servers to support external user access, you also need to install operating systems and prerequisite software for those servers, including Edge Servers and reverse proxy servers. For details about preparing servers to support external user access, see Preparing for Installation of Servers in the Perimeter Network in the Deployment documentation.

Install Windows Operating Systems on Servers

On each server that you are deploying, install the appropriate Windows operating system as follows:

  • Servers running Lync Server 2013   For details about the operating system requirements for servers running Lync Server 2013, see Server and tools operating system support in the Supportability documentation.

  • Database servers   For details about operating system requirements for database servers, including the back-end database, Archiving database, and Monitoring database, see the SQL Server documentation. For SQL Server 2012, see the SQL Server 2012 Books Online at http://go.microsoft.com/fwlink/p/?linkId=218015.

Note:
If you are installing Lync Server 2013 on Windows Server 2008 R2 with SP1, you must first install the update described in the Microsoft Knowledge Based article 2646886, “FIX: Heap corruption occurs when a module calls the InsertEntityBody method in IIS 7.5”, at http://go.microsoft.com/fwlink/p/?linkid=3052&kbid=2646886.

Install Windows Update on Servers

Install the following updates from Windows Update on each server:

  • Windows Update for servers running Lync Server 2013   For details about the updates from Windows Update that are required for servers running Lync Server 2013, see Additional software requirements in the Planning documentation.

  • Database servers   For details about the updates from Windows Update that are required for database servers, including the back-end database, Archiving database, and Monitoring database, see the SQL Server 2012 documentation. For SQL Server 2012, see the SQL Server 2012 Books Online at http://go.microsoft.com/fwlink/p/?linkId=218015.

Install Other Prerequisite Software on Servers

Lync Server 2013 requires the installation of the following additional software on servers:

  • Prerequisite software for servers running Lync Server 2013   The additional software prerequisites for servers running Lync Server 2013 depend on the server role being deployed. For details about the specific software requirements for each server, see Additional software requirements in the Planning documentation.

  • Windows Identity Foundation   Lync Server 2013 requires the installation of Windows Identity Foundation in order to support server-to-server authentication scenarios. To verify that it has already been installed on your computer, go to Control Panel, click Programs and Features, View installed updates, and look under Microsoft Windows. For details about installing Windows Identity Foundation, see http://go.microsoft.com/fwlink/p/?linkId=204657.

  • Microsoft .NET Framework 4.5   The 64-bit edition of Microsoft .NET Framework 4.5 is required for Lync Server 2013.

  • Prerequisite software for database servers   For details about the Windows Update required for database servers, including the back-end database, Archiving database, and Monitoring database, see the SQL Server 2012 documentation at http://go.microsoft.com/fwlink/p/?linkId=218015.

    Note:
    Lync Server 2013 automatically installs Microsoft SQL Server 2012 Express on each Standard Edition server and each server running Lync Server 2013 on which the local configuration store is located.

  • Windows Media Format Runtime   All Front End Servers and Standard Edition servers where conferencing will be deployed must have the Windows Media Format Runtime installed. The Windows Media Format Runtime is required to run the Windows Media Audio (.wma) files that the Call Park, Announcement, and Response Group applications play for announcements and music.

    Note:
    For Windows Server 2012 and Windows Server 2012 R2 the Windows Media Format Runtime installs with Microsoft Media Foundation.
    Note:
    For Windows Server 2008 and Windows Server 2008 R2 the Windows Media Format Runtime installs as part of the Windows Desktop Experience. It is recommended that you install Windows Desktop Experience before you install Lync Server 2013. If Lync Server 2013 does not find this software on the server, it will prompt you to install it, and then you must restart the server to complete installation.
