вот разобрался
X++:
CrmAuthenticationToken token = new CrmAuthenticationToken();
token.AuthenticationType = 0;
token.OrganizationName = "companyName";
CrmService crmService = new CrmService();
crmService.CrmAuthenticationTokenValue = token;
crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;
//crmService.Credentials = new System.Net.NetworkCredential("CRMTest", "123", "office");
//AppSettingsReader appSettings = new AppSettingsReader();
//crmService.Url = appSettings.GetValue("CrmSdk.CrmService", Type.GetType("System.String")).ToString();
crmService.Url = "http://darkstar:5555/MSCRMServices/2007/CrmService.asmx";
всем спасибо
