Cannot locate wdsl

Hi everyone,

We have an IIS that redirects to our portal. Our wsdl is deployed on the Portal and we have a requirement to access the wsdl(through an application) but only through the IIS. The problem is when the user tries to access the application which uses the wsdl through the IIS url, he is not able to run the application. Whereas when the user tries to access the application by using the portal URL directly , he is able to do that sucessfully.Could you please tell us how do we rectify this problem

Regards,

Melwyn
