publishing web service on 3 different IIS gets different result,Metadata publishing for this service is currently disabled

Question

I am programming a web service . When I publish the web service on Server1 (Windows 2012 With IIS 8),it works fine,but if I publish on Server2 (Windows 2012 With IIS 8), it gives following error

Metadata publishing for this service is currently disabled.

I have tested on Server3 (Windows 2019 With IIS 10), I get the above error

it seems that it might be the IIS setting , because in server1 it is working fine.

This is the web.Config of the service

   <?xml version="1.0"?>
 <configuration>

  <connectionStrings>

<add name="ECartContext" connectionString="metadata=res://*/ECartModel.csdl|res://*/ECartModel.ssdl|res://*/ECartModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=databaseServer;initial catalog=ECart;integrated security=True;Connection Timeout=30;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

          type="System.Diagnostics.XmlWriterTraceListener"
          initializeData= "c:\log\Traces.svclog" />
    </listeners>
  </source>
</sources>
</system.diagnostics>
 </configuration>

with this config the service works on Server1 only, not Server2 and Server3

how can I check the problem?

You need to add the endpoint in the servicemodel:

    <services>
        <service name="WcfService2.Service1" behaviorConfiguration="ManagementServiceBehaviour">
            <endpoint address="" contract="WcfService2.IService1" binding="basicHttpBinding"></endpoint>
        </service>
    </services>

I suspect that you have an endpoint in server1 but there is no endpoint in serve2 and server3.
