Default Behavior

Net.Tcp Port Sharing Service is a Win32 service. In Windows 8 it is disabled and therefore it won't start under any conditions. When the Net.Tcp Port Sharing Service is started, it runs as NT AUTHORITY\LocalService in a process of SMSvcHost.exe, sharing it with other services. If Net.Tcp Port Sharing Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the NetTcpPortSharing service hasn't been started.
