  Hi,

  I am getting Sporadic errors of "Access denied" for a custom page accessing CRM 4.0 using SDK.

  Custom page works fine for a while and later starts giving "Access denied" and then all users starts getting the same error on this page. Now if I restart IIS, page again starts working fine for a while  and  later on it again starts giving the same error.

   

   

  The CRM webservice connection details used -

   

  service = new CrmService();

  service.Url = CrmServerURL;

  service.Credentials = CredentialCache.DefaultCredentials;

  service.CrmAuthenticationTokenValue = new CrmAuthenticationToken();

  service.CrmAuthenticationTokenValue.AuthenticationType = 0;

  service.CrmAuthenticationTokenValue.OrganizationName = "XXX";

  //service.UnsafeAuthenticatedConnectionSharing = true;

  if (UserId != Guid.Empty)

  {

  service.CrmAuthenticationTokenValue.CallerId = UserId;

  }

   

  service.PreAuthenticate = true;

   

   

  *** The event viewer log shows following details- ***

   

  System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) +533199
  System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) +204
  

  Help  appreciate

   

  Thanks,

  Vijayendra
