WCF Service client problem - wcf

Question

I'm trying to create a client for a WCF service that I have hosted on IIS 5.1.I'm getting a strange problem: I can access the service through a browser just fine, I see the "You have created a service" page, but whenever I try running svcutil (as suggested by the same page)
svcutil.exe http://my.host.name/SampleService/SampleService.svc?wsdl
I get the following error:
Error: Cannot obtain Metadata from http://localhost.ms.com/SampleService/SampleS
ervice.svc?wsdl
If this is a Windows (R) Communication Foundation service to which you have acce
ss, please check that you have enabled metadata publishing at the specified addr
ess. For help enabling metadata publishing, please refer to the MSDN documentat
ion at http://go.microsoft.com/fwlink/?LinkId=65455.
WS-Metadata Exchange Error
URI: http://localhost.ms.com/SampleService/SampleService.svc?wsdl
Metadata contains a reference that cannot be resolved: 'http://localhost.ms.
com/SampleService/SampleService.svc?wsdl'.
The HTTP request is unauthorized with client authentication scheme 'Anonymou
s'. The authentication header received from the server was 'Negotiate'.
The remote server returned an error: (401) Unauthorized.
HTTP GET Error
URI: http://localhost.ms.com/SampleService/SampleService.svc?wsdl
There was an error downloading 'http://localhost.ms.com/SampleService/Sample
Service.svc?wsdl'.
The request failed with an empty response.
If you would like more help, type "svcutil /?"
What could be causing this problem?
EDIT: Could it be a problem with IIS itself? Incorrectly set permissions for example?

Answer 1

I think that this is the relevant error:
The HTTP request is unauthorized with client authentication scheme 'Anonymous'.
The authentication header received from the server was 'Negotiate'.
Is the web service password protected or using integrated Windows authentication? If I remember correctly, svcutil can't log on with integrated authentication to a web service. When you use a browser it works just fine, becuase it handles the authentication in the background for intranet environments.
One option is to download and save the wsdl manually and then point svcutil to use the downloaded wsdl file to generate the classes. You probably have to download some files that are referenced by the wsdl too and edit the references.
