You should use Credentials property to pass the windows credentials to the web service. If you wish to pass current windows user’s credentials to the service then request.Credentials = CredentialCache.DefaultCredentials; should do the trick.

Therefore, authentication fails if the FQDN or the custom host header that you use does not match the local computer … Read more
