Dell Warranty Information

Hello,

I am attemting to configure our SCCM to report on warranty status of all our Dell systems but having little problem getting the sms_def.mof to work with the insert mentioned inScott Keiffer's blog:

//  <:[-<>>>>>>>>>>>>>>>>>>>>>>Begin>>-Warranty Info-<<Begin<<<<<<<<<<<<<<<<<<<<<<>=]:>
#pragma namespace ("\\\\.\\root\\cimv2\\SMS")
[ SMS_Report (TRUE), SMS_Group_Name ("Warranty Info"), SMS_Class_ID ("CUSTOM|Warranty_Info|4.0") ]
class Warranty_Info : SMS_Class_Template
{
  [SMS_Report(TRUE)] datetime DateScriptRan;
  [SMS_Report(TRUE)] string ServiceTag;
  [SMS_Report(TRUE)] string SystemType;
  [SMS_Report(TRUE)] datetime ShipDate;
  [SMS_Report(TRUE)] string DellIBU;
  [SMS_Report(TRUE), Key] string Description;
  [SMS_Report(TRUE)] string Provider;
  [SMS_Report(TRUE)] datetime StartDate;
  [SMS_Report(TRUE)] datetime EndDate;
  [SMS_Report(TRUE)] uint32 DaysLeft;
  [SMS_Report(TRUE)] boolean WarrantyExtended;
};
//  <:[-<>>>>>>>>>>>>>>>>>>>>>>End>>-Warranty Info-<<END<<<<<<<<<<<<<<<<<<<<<<>=]:>

When I look in to the inventoryagent.log on the physical server, I keep seeing an error:

Unknown error encountered processing an instance of class Warranty_Info: 80041017

Am I missing something?
