Создание карточки через консольное приложение

[moskalevas]

Добрый день!
Пытаюсь создать консольное приложение.При его запуске должна создаваться карточка ПРЕДЛОЖЕНИЯ с заполненными обязательными полями.
Написал небольшой код.Выдаётся ошибка: The request failed with HTTP status 401: Unauthorized.
Подскажите в чём может быть ошибка.

static void Main(string[] args)
{
// Create and configure the CrmDiscoveryService Web service proxy.
CrmDiscoveryService discoveryService = new CrmDiscoveryService();
discoveryService.UseDefaultCredentials = true;
discoveryService.Url = "http://[адр_серв]/MSCRMServices/2007/AD/CrmDiscoveryService.asmx";
// Retrieve the list of organizations that the logged on user belongs to.
RetrieveOrganizationsRequest orgRequest = new RetrieveOrganizationsRequest();
//orgRequest.UserId = args[0];
//orgRequest.Password = args[1];
RetrieveOrganizationsResponse orgResponse = (RetrieveOrganizationsResponse)discoveryService.Execute(orgRequest);
// Locate the target organization in the list and Decalre the Security Token to Access CrmService.
CrmService service = new CrmService();
CrmAuthenticationToken token = new CrmAuthenticationToken();
foreach (OrganizationDetail orgDetail in orgResponse.OrganizationDetails) // It is only One organization in our case ..
{
Console.WriteLine("*Organization : " + orgDetail.OrganizationName);
token.OrganizationName = orgDetail.OrganizationName;
Console.WriteLine("*Organization Url : " + orgDetail.CrmServiceUrl);
service.Url = orgDetail.CrmServiceUrl;
}
