The Windows Event log uses the previous name (Office HTML Viewer Service) when referring to the Document Conversions Load Balancer Service.
Use the Services on Server page in Central Administration to repair the configuration information for the of the Document Conversions Load Balancer Service. For example, if the problem is that the load balancer cannot use the specified port number because the port is being used by a different application using .NET remoting, you can specify a different port number to use.
Ensure that the configuration file (Microsoft.Office.Server.Conversions.LoadBalancer.exe.config) has the correct IP address configured. Note that computers with multiple network adapters may be configured to use the wrong IP address.
