I'm having the following problem. I'm installing SharePoint 2010 Beta so I need to activate the windows feature "Windows Communication Foundation Non-HTTP Activation". The problem is I cannot activate it, i get the message: "An error has occurred. Not all features were successfully changed"
When i look at the log (C:\Windows\Logs\CBS\CBS.log) I found this error:
Process output: [l:186 "SMConfigInstaller[Error]: Failed in calling 'StartService' for service 'NetTcpActivator'. Error code: 0x8007042c
Anyone can give me a clue of what is happening here?
