Missing processor class

Hello

I have a problem with processor data gathering process. The issue concerns 15 machines (VMs) with OS Windows Server 2003. I can find missing data regarding CLN HW Processor.bak file:

       <data>

              <resource>

<row c6="9" />

             </resource>

      </data>

also CLN HW Processor Name Windows file is empty.

Below you can find the steps I have already performed in order to fix the issue:

• reinstall altiris agent
• reinstall inventory plugin
• install Microsoft Hotfix for Windows Server 2003 - KB932370
• check WMI: Win32_Processor and Win32_ComputerSystem
• agent logging (trace level enabled): I found the following messages:  
  • The data class does not have condition specified
  • CXMLDOMNodePtr::GetAttributeValue() error

Please could you give any hints in order to find source which causing this problem?
