In the server manager I have found the following error also, have tried the microsoft steps edit in component services management tool. but all the security options are greyed out - any ideas? I've also checked the settings in my iis application pool and they match with my test server.
The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
{A9E69610-B80D-11D0-B9B9-00A0C922E750}
and APPID
{A9E69610-B80D-11D0-B9B9-00A0C922E750}
to the user IIS APPPOOL\Classic .NET AppPool SID (S-1-5-82-1036420768-1044797643-1061213386-2937092688-4282445334) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
