Facility: WMI: Description: Genetic failure

Hi
While try to access Win32 programs remotely in Windows XP SP3, the following message encounters.
But it happen not with all workstations. About one third of the workstations are encountering such problems.
Is this due to SP3?
Should I go back to SP2?
Please suggest me. Our lab works are hampering.
