When you install Office Communications Server 2007 R2 Group Chat Server, the Group Chat Server Configuration Tool is automatically installed on the same computer. If your deployment includes multiple Group Chat servers, Lookup services, Channel services, and Web services, you must use the Group Chat Server Configuration Tool that is installed on the same computer as the service or server that you want to manage. However, you can configure pool-wide settings from any Group Chat Server.
To open the Server Configuration Tool
On the Group Chat Server, sign in using an account that is a member of the RTCUniversalServerAdmins group or an account that was specified as a super user during setup.
Click Start, point to All Programs, point to Administrative Tools, and then click Office Communications Server 2007 R2 Group Chat Server.
