I've got a WCF service that's using file-less activation:

```
  <bindings>
     <basicHttpBinding>
        <binding transferMode="Streamed">
           <security mode="Transport"/>
        </binding>
     </basicHttpBinding>
  </bindings>

  <serviceHostingEnvironment multipleSiteBindingsEnabled="true">
     <serviceActivations>
        <add relativeAddress="RulesService.svc"
             service="Big.Company.RulesService.Service, RulesService" />
     </serviceActivations>
  </serviceHostingEnvironment>

```

On some machines, I see the following exception:

> 
> Service
>  'Big.Company.RulesService.Service' has
>  zero application (non-infrastructure)
>  endpoints. This might be because no
>  configuration file was found for your
>  application, or because no service
>  element matching the service name
>  could be found in the configuration
>  file, or because no endpoints were
>  defined in the service element.
> 
> 
> 

As far as I can tell, `.svc` is correctly mapped to the .NET 4.0 activation module. The application is in the "ASP.NET v4.0" application pool, which is configured for .NET v4.0, using the integrated pipeline.

If I remove the Web.config file, I get a 404 error. If I rename the bin\RulesService.dll file, I get a 'service not found' exception.

What's wrong with it?

**Update:** It appears to be a problem when turning on SSL. If I connect using HTTPS, it's fine, *until I turn on 'Require SSL' in IIS*.
