I think "NET START W3SVC" doesn´t start all the stopped services:
C:\>NET STOP WAS /Y && NET START W3SVC
The following services are dependent on the Windows Process Activation Service service.
Stopping the Windows Process Activation Service service will also stop these services.
World Wide Web Publishing Service
Net.Tcp Listener Adapter
Net.Pipe Listener Adapter
Net.Msmq Listener Adapter
