Installing and Configuring Group Chat Server

 

Topic Last Modified: 2012-10-18

Important

You must uninstall previous versions of the Core Components of Microsoft Lync Server 2010 or Microsoft Office Communications Server, in addition to previous versions of the Microsoft Unified Communications Managed API (UCMA) before installing Microsoft Lync Server 2010, Group Chat. For details about uninstalling Core Components, see Microsoft Knowledge Base article 2407349, "Description of the cumulative update for Microsoft Office Communications Server 2007 R2, Core Components: September 2010" at https://go.microsoft.com/fwlink/p/?linkid=3052&kbid=2407349.

You use two wizards to install Lync Server 2010, Group Chat: the Group Chat Server Setup wizard and the Server Configuration wizard. The Group Chat Server Setup wizard installs the server and services on the computer. The Server Configuration wizard, which automatically opens upon completion of the Group Chat Server wizard, prepares the server and services for use in your environment.

To install Group Chat Server, you must have a certificate issued by the same certification authority (CA) as the one used by Lync Server 2010 internal servers for each server running the Lookup service, Channel service, and Web service. Make sure that you have the required certificate(s) before you start the Group Chat Server installation, especially if you are using an external CA. For details certificates, see Obtaining Certificates for Group Chat Server.

After you install the initial Group Chat Server instance, you can install additional Group Chat Server instances to create a Group Chat Server pool for scalability and failover.

Important

We recommend that you install all additional Group Chat Server instances in the same Lync Server trusted application pool. In this environment, all of the certificates for the Group Chat Servers must use the same pool fully qualified domain name (FQDN) (and not the Group Chat Server FQDN). You can make any entry for the certificate’s subject alternative name (SAN). We recommend that you use the following certificate for all server instances in the Group Chat Server pool: SN = “Group Chat Server Pool Name”; SAN = <any entry>.

These server instances must be installed on computers separate from the original Group Chat Server installation. If you plan to install a Compliance service, you can use the same wizard, but you must install it on a separate computer.

For details about scalability, see Capacity Planning in the Planning documentation.

Note

After completing installation, we recommend that you change the database role membership for the Channel service, Web Services, and Compliance service accounts from db_owner to ChannelServer, WebServer, and ComplianceServer, respectively. These new roles are created during installation. For details about assigning database roles, see Setting Up SQL Server Accounts, Rights, and Permissions.
