nav services started ?

How can I double check if the nas service is started for the job queue on microsoft dynamics nav2016 ?

I wonder if there a command line or option to display running services ?

The NAS is not a separate service in NAV 2016, it’s part of the core NAV service. And here you can either enable or disable it.

This is an old video about NAV 2013 when that was still a beta, but it still applies now:

You can see in ‘Services’ whether the service tier is running itself, but that does not tell you about individual parts of the service tier. Depending on what you configure NAS to do, it would show up as a background type session, which you would see in the sessions screen.
