Install Group Chat Server


Topic Last Modified: 2012-10-18

The following procedure describes how to install Microsoft Lync Server 2010, Group Chat as either a single-server topology or an additional server instance in a pooled topology. A server instance includes the Lookup service, Channel service, and Web service. If you want to install a Compliance service, you must install it on an additional computer using the same wizard that you use for installation.


Although the setup wizard gives you the option to install Group Chat Server and the Compliance service simultaneously on the same server, Group Chat Server does not support hosting both on the same computer. Make sure that during the installation, you select either Group Chat Server or the Compliance service, not both.

If you are installing an additional Lync Server 2010, Group Chat instance as part of a Group Chat Server pool, the established settings from the server pool are used, and some controls are unavailable for settings that are used by all Group Chat Servers. Shared settings include the following:

  • Microsoft Lync Server 2010   No controls are available.

  • **Lookup service **   Only the Password, Confirm Password, and Pool Communication Port boxes are available.

To install Group Chat Server, your computer must have the following software already installed:

  • Microsoft .NET Framework 3.5 SP1, which is used to run all Group Chat Server services because these services are written in .NET

  • Internet Information Services (IIS), which is used to host the Web service for the purpose of posting files to chat rooms


    Windows Server 2008 users must enable the IIS 6.0 Compatibility feature.

  • ASP.NET 2.0, which is used to build dynamic websites, web applications, and XML web services


    ASP.NET 2.0 is a web application that is part of the .NET Framework.

  • Message Queuing, which is used by the Group Chat Server Compliance service, if the Compliance service deployed.

The following applications are installed automatically if they are not already installed:

  • Lync Server 2010 Core Components

  • Visual C ++ 2008 Redistributable Runtime version 9.0.2102

  • Microsoft Unified Communications Managed API (UCMA) 3.0 Redistributable


For details about uninstalling Lync Server Core Components, see Microsoft Knowledge Base article 2407349, "Description of the cumulative update for Office Communications Server 2007 R2, Core Components: September 2010," at
