On all internal server roles, you must also make sure that Windows PowerShell command-line interface 3.0 and Microsoft .NET Framework 4.5, are installed.

Important:
Edge Servers and Edge pools have different requirements from servers deployed on the internal network. The requirements for the Edge Servers and Edge pools are listed later in this topic under Additional Software for Edge Servers.

Additionally, Microsoft .NET Framework 4.5 is required on any computer where you will run the Lync Server administrative tools or Microsoft Lync Server 2013, Planning Tool.

Windows PowerShell 3.0

Microsoft .NET Framework 4.5

Windows Identity Foundation in Lync Server 2013 requires the installation of Windows Identity Foundation in order to support server to server authentication scenarios. Windows Server 2008 R2 and Windows Server 2012 require different procedures to install the Windows Identify Foundation. Select your server operating system from the following list:

• Windows Server 2008 R2   For Windows Server 2008 R2, you check to see if it has already been installed on your computer. To do this, go to Add/Remove Programs, View Installed Updates, and look under Windows for the entry Windows Identity Foundation (KB974405). For details about installing Windows Identity Foundation, see http://go.microsoft.com/fwlink/p/?linkId=204657.

• Windows Server 2012   For Windows Server 2012, you use Server Manager to install the Windows Identity Foundation. In the Server Manager Add Roles and Features Wizard, select Features. Select Windows Identity Foundation 3.5 from the list. Click Next, then click Install.

All Front End Servers and Standard Edition servers must also run Internet Information Services (IIS) with certain modules. Additionally, all Front End Servers and Standard Edition servers where conferencing, Call Park application, Announcement, or Response Groups are deployed must run Windows Media Format Runtime.

Internet Information Services (IIS)

Windows Desktop Experience

Front End Servers require .NET 3.5, which is not installed by default on Windows Server 2012. To install it, put your Windows Server 2012 installation media in Drive D and type the following:

Copy Code

Add-WindowsFeature RSAT-ADDS, Web-Server, Web-Static-Content, Web-Default-Doc, Web-Http-Errors, Web-Asp-Net, Web-Net-Ext, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Http-Logging, Web-Log-Libraries, Web-Request-Monitor, Web-Http-Tracing, Web-Basic-Auth, Web-Windows-Auth, Web-Client-Auth, Web-Filtering, Web-Stat-Compression, Web-Dyn-Compression, NET-WCF-HTTP-Activation45, Web-Asp-Net45, Web-Mgmt-Tools, Web-Scripting-Tools, Web-Mgmt-Compat, Desktop-Experience, Telnet-Client, BITS -Source D:\sources\sxs

For details about installing .NET 3.5 on servers running Windows Server 2012, see "Microsoft .NET Framework 3.5 Deployment Considerations" at http://go.microsoft.com/fwlink/p/?linkid=275032.

Directors must run Internet Information Services (IIS), with the following modules:

• Static Content

• Default Document

• HTTP Errors

• ASP.NET

• .NET Extensibility

• Internet Server API (ISAPI) Extensions

• ISAPI Filters

• HTTP Logging

• Logging Tools

• Tracing

• Windows Authentication

• Request Filtering

• Static Content Compression

• IIS Management Console

• IIS Management Scripts and Tools

• Anonymous Authentication (This is installed by default when IIS is installed.)

• Client Certificate Mapping Authentication

Persistent Chat Front End Servers must run Message Queuing (also known as MSMQ), which is a component of Windows Server.

Edge Servers require the following software:

• Each server running Lync Server 2013 must have the correct release of Windows PowerShell 3.0 installed. For details, see Installing Windows PowerShell 3.0.

• Lync Server requires Microsoft .NET Framework 4.5. For Lync Server 2013 installed on Windows Server 2008 R2, you must manually install the 64-bit edition of Microsoft .NET Framework 4.5 on the server prior to installing Lync Server 2013. To manually install it, download the Microsoft .NET 4.5 Framework from the Microsoft Download Center at http://go.microsoft.com/fwlink/p/?LinkId=268529

• Windows Identity Foundation in Lync Server 2013 requires the installation of Windows Identity Foundation in order to support server to server authentication scenarios. Windows Server 2008 R2 and Windows Server 2012 require different procedures to install the Windows Identify Foundation. Select your server operating system from the following list:

  • Windows Server 2008 R2   For Windows Server 2008 R2, you check to see if it has already been installed on your computer. To do this, go to Add/Remove Programs, View Installed Updates, and look under Windows for the entry Windows Identity Foundation (KB974405). For details about installing Windows Identity Foundation, see http://go.microsoft.com/fwlink/p/?linkId=204657.

  • Windows Server 2012   For Windows Server 2012, you use Server Manager to install the Windows Identity Foundation. In the Server Manager Add Roles and Features Wizard, select Features. Select Windows Identity Foundation 3.5 from the list. Click Next, then click Install.

Do not install any Microsoft Internet Security and Acceleration (ISA) Server client software, or any other Winsock Layered Service Providers (LSP) software, on any Front End Servers or stand-alone Mediation Servers. Installing this software could cause poor media traffic performance.
