Error when adding web service reference in VS2012

Question

I am trying to add a reference to a web service for a new project in VS2012. I keep getting the below error:

There was an error downloading 'ServiceAddress/ConfigurationMgmt.wsdl/_vti_bin/ListData.svc/$metadata'. The request failed with HTTP status 400: Bad Request. Metadata contains a reference that cannot be resolved: 'ServiceAddress/ConfigurationMgmt.wsdl'. The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="CASM"'. The remote server returned an error: (401) Unauthorized. If the service is defined in the current solution, try building the solution and adding the service reference again.

The part that more confusing is that I am able to add and use a reference to the same web service using VS2010. If I open the VS2010 project in VS2012 and try to update the service reference I get the same error.

I have tried adding the service reference to new projects in VS2012, starting VS2012 under admin mode and restarting my pc.

I have also tried adding references to other services in VS2012 project that are available on our intranet and they seem to work fine.

Is there something basic that I am missing here? What else can I try to find out the reason behind this problem?

Change the web.config file in security tag,

<security mode="TransportCredentialOnly">
    <transport clientCredentialType="Anonymous"/>
    <message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>

i think this will hep you. if its not working then there is problem in your service provider deployment ACL
