Answer 1

Make sure your application pool identity account on your server has permissions to start that service. It works on your ASP.NET Development Server because it runs under your user account (admin) In a default IIS configuration, this account is Network service or ApplicationPoolIdentity (depending on IIS version) and usually cannot manage services.

So, change the pool account in IIS Manager (Application Pools/NameOfYourYourPool/Advanced Settings). You can use a built-in account or use one of your domain.
