I've read through what feels like Gigabytes of webpages addressing the cause and resolution of these errors yet they still persist. I'll provide all the info I know about our setup in the hopes that someone can help. I have 2 web front ends that run the Launcher service and 1 server that runs the Load Balancer service. The WFE's do not run the Load balancer Service and the server running the Load balancer service does not run the Launcher Service. The Launcher Service Settings in Central Admin Show the correct Load Balancer Server. Port number is listed as 8082 (I'm assuming this is what the launcher communicates to the Balancer on but couldn't find any info on it). The registry LauncherSettings on the web front ends AND the Load Balancer server for LoadBalanceUrl point to http://domainname:8093/HtmlTrLoadBalancer. The port entry reads 8082 The registry LoadBalancerSettings only show the Port key set to 8093. The Load Balancer Settings in Central Admin for the Comunication scheme is https. It says this should match what is in the config xml file for the load balancer server, however, I do not see any entry in the log for this. here is the contents of that file: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <sectionGroup name="HtmlTransform"> <section name="LoadBalancerSettings" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> </sectionGroup> </configSections> <HtmlTransform> <LoadBalancerSettings> <add key="keyPort" value="8093"/> <add key="keyMyURL" value=""/> <!-- can be "RoundRobin" or "ShortestQueue" --> <add key="keyBalanceScheme" value="ShortestQueue"/> </LoadBalancerSettings> </HtmlTransform> <system.runtime.remoting> <application> <service> <wellknown mode="Singleton" type="Microsoft.Office.HtmlTrans.HtmlTrLoadBalancer,Microsoft.Office.Server.Conversions.LoadBalancer" objectUri="HtmlTrLoadBalancer"/> </service> </application> </system.runtime.remoting> </configuration> The Config for the Launcher is: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <sectionGroup name="HtmlTransform"> <section name="LauncherSettings" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <section name="ExtensionToAppMappings" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> </sectionGroup> </configSections> <HtmlTransform> <LauncherSettings> <add key="keyUseSinglecall" value="false"/> <add key="keyLoadBalancerURI" value=""/> <add key="keyTransAppFolder" value=""/> <add key="keyOutputFolder" value=""/> <add key="keyAllowedCrashesBeforeBlacklisting" value="2"/> <add key="keyNumMultiCallsBeforeReboot" value="20"/> <add key="keyPort" value="8082"/> <!-- add key="keyIPExclude" value="192\.168\.\d{1,3}\.\d{1,3}" / --> </LauncherSettings> <ExtensionToAppMappings> <add key="doc" value="wwxlate.exe"/> <add key="xls" value="xlxlate.exe"/> <add key="ppt" value="pptxlate.exe"/> <add key="pps" value="pptxlate.exe"/> </ExtensionToAppMappings> </HtmlTransform> <system.runtime.remoting> <application> <service> <wellknown mode="Singleton" type="Microsoft.Office.HtmlTrans.HtmlTrLauncher,Microsoft.Office.Server.Conversions.Launcher" objectUri="HtmlTrLauncher"/> </service> </application> </system.runtime.remoting> </configuration> The port number is set to 8093 (for Load Balancer Service Settings in Central Admin) The Launcher Service runs under the Local System Account and is allowed to interact with the desktop. The Load Balancer runs under the Network Service Account. When anything is done to a setting we restart Balancer and then the launchers utilizing the stsadm command. Our SharePoint logs show the following 2 errors: 12/20/2010 12:34:56.33 Microsoft.Office.Server.Convers (0x1AFC) 0x1B20 Document Conversions Launcher Service 6102 Critical LoadBalancer.RegisterLauncher failed: Unable to connect to the remote server 12/20/2010 12:34:56.33 Microsoft.Office.Server.Convers (0x1AFC) 0x1B20 Document Conversions Launcher Service 7jgs Medium Loadbalancer not running or available to launcher id 1 The servers are all pingable from each other so Im not sure if that is the issue. I also checked the host files on each machine to insure that they were looking in the right place. The HVU_machineName user has logon locally rights. It is a member of the Guest account which I thought was odd but I'm assuming that is the default. The last bit of info I can report is that at C:\Program Files\Microsoft Office Servers\12.0\Bin on one of our launchers (it is not on the other launcher server) there is a folder called HtmlTrLauncher. When I click on this directory (whether logged in with my SA account or as the CA user) I get a popup error that reads "C:\Program Files\Microsoft Office Servers\12.0\Bin\HtmlTrLauncher is not accessible. \n Access is denied." I do not know if this is by design or is an issue I should try to resolve (not sure how though). Right-Click property shows that HVU has full control as does the system account. Thanks for taking the time to look at this!
