Installing Group Chat Server

Communications Server 2007 R2

Topic Last Modified: 2009-04-28

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

To install Office Communications Server Group Chat Server, you must have a certificate issued by the same certification authority (CA) as the one used by Office Communications Server 2007 R2 internal servers for each server running Lookup service, Channel service, and Web service. Make sure that you have the required certificate(s) before you start the Group Chat 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. 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 Office Communications Server 2007 R2 Planning and Architecture documentation.

After completing installation, we recommend that you change the database role membership for the Channel service, Web service, 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 and Permissions.
