Dear all, I ran WMIDiag utility on one of our Primay SMS Server. I traced out couple of errors. It says couple of classes missing. We traced this issue, when a third party tool is trying to pull advertisements data from SMS Provider. Is there any way we can get this sorted out without repairing the SCCM. 05:44:57 (0) ** 1 error(s) 0x80041011 - (WBEM_E_PROVIDER_NOT_FOUND) Provider referenced in the schema does not have a corresponding registration.
