When it is necessary, you can restart servers from the Group Chat Server Configuration Tool.
When you restart servers from the Group Chat Server Configuration Tool, the Channel, Lookup, and Compliance services are restarted. The Web service is not restarted because it picks up changes automatically. For details about restarting an individual service, see Monitoring, Starting, or Stopping Services.
To restart servers
In the Group Chat Server Configuration Tool, on the Filemenu, click Restart Server.
In the Restart Confirmationdialog box, click Yes.
