How to read successfully a web app service in the browser

I am not a web developer, i am sys admins and i am trying to assist the web apps support dpt.

We have to environments:
UAT and PROD

In UAT if i browse to this URL:
http://pe01.uat.lcl/EWS-DEV/EngineService.svc I get the following on the browser

EngineService Service

You have created a service.

To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:

svcutil.exe http://pe01.uat.lcl/EWS-DEV/EngineService.svc?wsdl

You can also access the service description as a single file:

http://pe01.uat.lcl/EWS-DEV/EngineService.svc?singleWsdl

This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:

C#
class Test
{
    static void Main()
    {
        EngineServiceClient client = new EngineServiceClient();
        // Use the 'client' variable to call operations on the service.
        // Always close the client.
        client.Close();
    }
}

Visual Basic
Class Test
    Shared Sub Main()
        Dim client As EngineServiceClient = New EngineServiceClient()
        ' Use the 'client' variable to call operations on the service.
        ' Always close the client.
        client.Close()
    End Sub
End Class

Select allOpen in new window

But if I go to PROD and browse
http://pe01.prod.lcl/EWS-PROD/EngineService.svc I get the following:

Server Error
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable
