The Group Chat service does not work after you restart a computer that is running Office Communications Server 2007 R2 Group Chat Server

After you restart a computer that is running Microsoft Office Communications Server 2007 R2 Group Chat Server, the Group Chat service does not start. This occurs when the Channel Server (mgcchans) or the Compliance Server (mgccompl) tries to start before Microsoft Message Queuing starts. However, the Channel Server cannot function without Message Queuing. Therefore, the Group Chat service does not start.
